Criminalistics is a branch of forensic science focused on collecting, examining, and interpreting physical evidence. Criminology studies crime, lawbreaking, justice institutions, and society’s responses to crime through social science theories and research methods.
The fields overlap in their interest in crime, but they prepare students for substantially different work. A California student targeting chemical analysis, DNA testing, toxicology, trace evidence, firearms examination, or another crime-laboratory specialty needs a science-intensive education. A student interested in crime research, policy, policing, corrections, victim services, program evaluation, or social inequality will usually find a closer match in criminology.
This is not a directory of every California program. The program examples below illustrate how the two fields differ in curriculum, prerequisites, practical training, and career alignment.
Criminalistics and criminology compared
| Comparison point | Criminalistics | Criminology |
|---|---|---|
| Central question | What does the physical evidence show? | Why does crime occur, how is it measured, and how do institutions and communities respond? |
| Academic foundation | Chemistry, biology, physics, mathematics, laboratory methods, and forensic science | Sociology, law, public policy, psychology, statistics, research methods, and related social sciences |
| Evidence or data studied | DNA, biological material, drugs, toxicology samples, fibers, glass, firearms evidence, documents, fingerprints, digital evidence, and other physical evidence | Crime statistics, surveys, interviews, policies, institutions, neighborhoods, legal decisions, correctional systems, and social behavior |
| Common coursework | General and organic chemistry, quantitative analysis, biology, genetics, biochemistry, instrumental analysis, microscopy, toxicology, forensic biology, and evidence interpretation | Criminological theory, crime measurement, policing, punishment, law and society, inequality, research design, statistics, public policy, and qualitative methods |
| Typical practical preparation | Laboratory exercises, evidence handling, instrumentation, mock crime scenes, technical reporting, quality procedures, and testimony | Research projects, statistical analysis, interviews, surveys, policy analysis, internships, community projects, and program evaluation |
| California career examples | Criminalist, forensic scientist, forensic science technician, crime-lab analyst, forensic chemist, forensic biologist, and some crime-scene positions | Crime analyst, research assistant, policy analyst, victim-services professional, correctional program employee, justice-program evaluator, and graduate-level criminologist |
| Laboratory science requirement | Usually substantial for laboratory careers | Usually limited or absent unless added separately |
| Typical degree path | A bachelor’s degree in forensic science, chemistry, biology, biochemistry, or another qualifying natural science; graduate study for advanced specialization | A bachelor’s degree for many justice, policy, service, or research-support positions; a master’s degree or doctorate for many professional sociologist and academic research roles |
| Relevant specialized accreditation | FEPAC may apply to eligible forensic science programs | FEPAC does not evaluate criminology programs as a category |
The California Department of Justice’s California Criminalistics Institute draws the line clearly. It defines criminalistics as the forensic science area concerned with collecting, preserving, examining, and interpreting physical evidence. It distinguishes that work from criminology, which addresses the social issues and effects associated with crime.
What criminalistics covers
Criminalistics applies scientific methods to evidence that could help answer a legal or investigative question. The work can begin at a scene, continue in a laboratory, and end with a technical report or courtroom testimony.
The physical evidence involved varies by assignment and laboratory. California criminalists may work with DNA and other biological material, controlled substances, toxicology samples, trace evidence, firearms, questioned documents, or related evidence. The broader forensic field also encompasses fingerprints, digital evidence, biometrics, and quality assurance, although agencies often organize those specialties into separate units or job classifications.
A laboratory criminalist needs more than familiarity with criminal investigations. The person must be able to perform scientific measurements, use appropriate controls, operate or understand laboratory instruments, evaluate uncertainty, document methods, interpret results, and explain conclusions within the limits of the evidence. Chemistry, biology, statistics, and laboratory practice are therefore central rather than peripheral parts of the education.
The term also extends beyond bench analysis. California’s entry-level state Criminalist classification includes technical laboratory analysis and may include assistance with crime-scene examinations and scientific investigations. Sacramento County likewise describes criminalists as forensic caseworkers who may conduct scene investigations.
Even so, criminalist is not a universal synonym for crime scene investigator. One department may send laboratory criminalists to major scenes. Another may use civilian crime scene technicians, evidence technicians, latent print personnel, forensic photographers, or sworn police officers. Job titles must be read in the context of the employing agency.
What criminology covers
Criminology treats crime as a social phenomenon. It examines why crime occurs, how crime is defined and measured, how laws and institutions influence behavior, and how communities respond to offending and victimization.
The field draws heavily from sociology, but many programs also use psychology, political science, economics, history, law, public policy, and geography. Students may examine theories of offending, policing strategies, punishment, correctional institutions, inequality, neighborhood conditions, public perceptions of crime, victimization, and the effects of government policy.
Criminology is analytical, not merely a general overview of police and courts. Research methods may include surveys, interviews, observation, ethnography, archival work, experiments, quasi-experiments, secondary datasets, spatial analysis, and statistical modeling. A research-intensive curriculum can demand substantial quantitative and writing skills even though it does not include the chemistry sequence needed for forensic laboratory work.
The exact job title “criminologist” is less common than the name of the academic field. The U.S. Bureau of Labor Statistics treats criminologists as sociologists who specialize in crime. Many people educated in criminology work under other titles, including analyst, researcher, program evaluator, policy specialist, victim-services professional, or justice-agency employee.
Professional sociologist and academic research roles commonly require graduate education. A bachelor’s degree can still support entry into research assistance, public service, justice agencies, community programs, social services, and policy-related work, but the degree does not guarantee employment under the title criminologist.
How criminalistics differs from criminal justice and CSI
Several adjacent fields add to the confusion.
Criminal justice generally emphasizes justice-system institutions and practice, including policing, courts, corrections, administration, and procedure. Some criminal justice programs include criminological theory and research, while others are oriented more heavily toward professional practice.
Criminology emphasizes the study of crime and social responses to it. Depending on the university, it may be housed in sociology, social ecology, justice studies, or a criminal justice department.
Criminalistics uses natural and physical sciences to examine evidence. It is part of forensic science.
Crime scene investigation concentrates on recognizing, documenting, recovering, preserving, and transporting evidence. Relevant skills include photography, sketching, fingerprints, scene documentation, reconstruction, chain of custody, report writing, and testimony. Scene investigation can be taught within a forensic science degree, a criminal justice program, a certificate, or an agency training program.
CSI education and criminalistics overlap, but the jobs are not identical. A scene technician may collect and document a bloodstain without conducting the DNA analysis. A forensic biologist may analyze the submitted sample without having attended the scene. Some positions combine portions of both functions.
A general criminal justice degree, a criminology major, and a short CSI certificate are not substitutes for a full laboratory-science curriculum when an employer requires chemistry, biology, quantitative analysis, or another specified natural science.
California criminalist requirements make the difference concrete
California’s state Criminalist classification provides a practical test of whether a degree plan supports laboratory employment. Under the education pattern published in the state Criminalist examination bulletin, applicants need a college major in a physical or biological science, eight semester hours of general chemistry, and three semester hours of quantitative analysis.
The examination covers scientific crime-scene methods, biological-fluid testing, toxicology, trace evidence, firearms, questioned documents, chromatography, microscopy, photography, applied research, and courtroom testimony. These are science and evidence competencies, not merely subjects within the general study of crime.
A standard criminology major usually fails this education pattern because it does not require a physical or biological science major or the specified chemistry coursework. Adding one introductory forensic science elective does not repair that gap. A student would need to complete a qualifying science major and the required chemistry courses, or build another transcript that fits the employer’s published route.
The state requirements are not a universal California standard. Local agencies publish their own classifications:
- Kern County’s 2026 Criminalist I recruitment accepted degrees in chemistry, biochemistry, criminalistics, forensic science, biology, or a closely related laboratory science. Its coursework expectations included areas such as quantitative analysis, organic chemistry, molecular biology, genetics, and statistics, depending on the discipline.
- Sacramento County accepts several natural or physical science majors, as well as criminalistics or forensic science programs with a natural or physical science emphasis. Its classification includes laboratory analysis, equipment operation, technical reports, testimony, and possible crime-scene work.
- The City of Los Angeles requires a four-year degree with a major in a physical or natural science and specified general chemistry coursework. Its criminalists may also respond to scenes outside regular work hours and work around biological or chemical hazards.
These examples show why the word “forensic” in a degree title is not enough. A forensic studies program could contain mostly survey courses, while a chemistry degree could satisfy much of a laboratory’s scientific foundation without using “forensic” in its name.
The most reliable planning method is to work backward from several employer specifications. Compare the intended degree course by course with state and local requirements. General chemistry, organic chemistry, quantitative or analytical chemistry, biochemistry, molecular biology, genetics, statistics, physics, calculus, instrumentation, and laboratory hours can all affect eligibility for a particular specialty.
California curriculum examples
California universities use varied degree names, and the curriculum is more informative than the label. The following programs are examples rather than rankings or a complete statewide inventory.
San José State University BS in Forensic Science
San José State University offers a Bachelor of Science in Forensic Science with concentrations in biology, chemistry, digital evidence, and crime scene investigation. The program combines science with applied forensic subjects, including biology, DNA analysis, photography, organic and inorganic chemistry, biochemistry, genetics, instrumental analysis, toxicology, physical evidence, firearms, toolmarks, arson, and explosives.
The concentration structure allows students to move toward different parts of forensic work. Biology and chemistry are especially relevant to crime-laboratory positions because California criminalist classifications often screen applicants through their science major and transcript. Digital evidence follows a different technical route, while CSI emphasizes scene processing and documentation.
SJSU describes the degree as providing crime-laboratory and crime-scene training, and its current roadmaps include practical or experiential work. The major is impacted, and the CSI concentration has limited capacity under the department’s current materials.
The university states that its forensic science curricula meet FEPAC educational standards. That wording is different from current FEPAC accreditation and should be preserved as written. FEPAC accreditation requires a separate formal decision by the accrediting commission.
SJSU also offers justice studies with a criminology concentration. Housing forensic science and criminology in the same department does not make the curricula interchangeable. The forensic science degree emphasizes natural science and evidence, while the criminology concentration emphasizes theory, methodology, critical inquiry, institutions, and responses to crime.
UC Irvine BA in Criminology, Law and Society
The University of California, Irvine offers a clear example of social-science criminology. Its BA in Criminology, Law and Society examines law, crime, behavior regulation, and social responses through anthropological, economic, historical, political, psychological, and sociological perspectives.
The 2026-27 catalog lists an 11-course, 44-unit major. Subjects include criminological theory, crime and public policy, the community context of crime, crime measurement, spatial criminology, policing, punishment, inequality, and law. Related methods coursework includes qualitative research, quantitative analysis, statistics, interviews, surveys, experiments, archival research, secondary datasets, and data visualization.
This curriculum develops a different type of analytical skill from criminalistics. Students learn to evaluate social evidence, research designs, institutions, policies, and patterns. They are not being trained to perform controlled-substance identification, toxicology testing, DNA analysis, or instrumental chemical analysis.
The degree aligns more closely with justice agencies, public policy, legal studies, regulation, direct services, research, and graduate education. It would need substantial additional science preparation to fit California criminalist specifications.
UC Davis MS in Forensic Science, Criminalistics Track
UC Davis offers an in-person Master of Science in Forensic Science with DNA and Criminalistics tracks. The degree requires 54 quarter units and provides thesis and capstone routes.
Its admission preparation demonstrates the scientific foundation expected at the graduate criminalistics level. Appropriate undergraduate preparation includes a physical or natural science, engineering, or a closely related field. Published prerequisites include chemistry, organic chemistry, physics, calculus, and statistics.
The Criminalistics track addresses instrumental analysis, trace evidence, drug chemistry, toxicology, physical evidence, ethics, and the relationship between law and science. Official program materials also describe laboratory work, research, mock crime scenes, and moot-court testimony.
This is graduate specialization rather than an entry-level substitute for missing undergraduate science. A criminology graduate who lacks the prerequisite chemistry, physics, calculus, and statistics would first need to complete that foundation.
FEPAC listed the UC Davis program as seeking accreditation in an April 2025 action notice. An application or review status is not an accreditation decision, so the program is not described here as FEPAC-accredited.
Cal State LA MS in Criminalistics
California State University, Los Angeles offers an MS specifically titled Criminalistics. Published preparation includes general chemistry, organic chemistry with laboratories, quantitative analysis, physics, and biostatistics. The university also publishes a minimum 3.0 GPA for admission consideration.
Graduate study covers scientific methods, experimentation, measurement, physical-evidence evaluation, research, law, ethics, policy, and forensic practice. Students complete a research project as the graduate capstone, and the program encourages internship participation. Most courses are scheduled during evening hours.
The program is based at the Hertzberg-Davis Forensic Science Center, which involves Cal State LA, the Los Angeles Police Department Scientific Investigation Division, and the Los Angeles County Sheriff’s Department Scientific Services Bureau. This location provides a professional forensic setting, though it does not guarantee an internship or employment.
The prerequisites are the central comparison point. Cal State LA expects chemistry laboratories, quantitative analysis, physics, and biostatistics before graduate criminalistics study. Those subjects are generally absent from an undergraduate criminology core.
Fresno State BS in Criminology
Fresno State’s Bachelor of Science in Criminology offers options in Corrections, Law Enforcement, and Victimology. The department describes an interdisciplinary curriculum combining theoretical and applied material for criminal justice employment and graduate study.
This is an applied criminology example rather than a research-intensive program identical to UC Irvine’s. The Corrections option can support interests in correctional systems and rehabilitation. Law Enforcement addresses policing and justice-agency work. Victimology focuses attention on victims, services, and institutional responses.
For the Fall 2026 admission cycle, Fresno State identifies all three options as similar transfer pathways for the Administration of Justice Associate Degree for Transfer. That can be useful for California community college students planning a CSU route.
The major is distinct from Fresno State’s BS in Forensic Behavioral Sciences. More importantly for laboratory planning, the criminology options are not presented as chemistry-based preparation for criminalist employment.
Which field fits specific career goals?
Crime-laboratory analysis
Choose criminalistics, forensic science with sufficient natural science, or a qualifying major such as chemistry, biology, biochemistry, microbiology, or physics.
Laboratory employers care about the exact science foundation. A forensic chemistry position may call for organic chemistry, quantitative analysis, and instrumental methods. Forensic biology may require genetics, molecular biology, biochemistry, statistics, and substantial laboratory experience. Toxicology can demand chemistry and biological science beyond an introductory sequence.
A natural science degree can be a safer route than a lightly scientific “forensic” degree because many California specifications explicitly accept traditional science majors. Forensic coursework can then be added through electives, internships, research, or graduate study.
Crime scene investigation
The best academic preparation depends on how the target agency organizes scene work. Relevant coursework includes evidence recognition, photography, fingerprints, documentation, recovery methods, reconstruction, chain of custody, report writing, and courtroom testimony.
Some civilian CSI positions may accept forensic science, criminal justice, or related education paired with scene-processing skills. Some departments use sworn officers, which adds academy, physical, background, and law-enforcement requirements. Other agencies send criminalists to scenes and expect a stronger natural science foundation.
A CSI concentration can support field evidence work without providing the depth needed for every laboratory analyst position. Conversely, a chemistry major can satisfy laboratory screening but provide little practice in photography, sketching, or scene documentation unless those courses are added.
Crime analysis
Crime analysis is separate from criminalistics. California’s Crime Analyst I classification includes database searches, records and data analysis, pattern identification, fingerprint comparisons, information validation, reports, and support for law-enforcement agencies. Qualification routes include college coursework, relevant experience, or an approved crime and intelligence analysis certificate.
Criminology, criminal justice, statistics, geographic information systems, data analysis, and research methods can all be relevant to this path. Laboratory chemistry is not part of the state classification’s central preparation.
The title should not be reduced to predictive mapping or advanced statistical modeling. Entry-level crime analyst work can involve records, databases, information quality, identification processes, and operational agency support.
Research and policy
Criminology is the closer academic fit for studying crime rates, institutions, laws, punishment, policing, community conditions, victimization, inequality, and program outcomes.
Useful preparation includes statistics, research design, data management, survey methods, interviewing, policy analysis, geographic analysis, and clear analytical writing. Students aiming for independent research, professional sociology, or university teaching should plan for graduate study.
A criminology curriculum with strong methods training is generally more useful for this goal than one consisting mainly of broad justice-system surveys. UC Irvine’s methods and measurement content illustrates the difference.
Corrections, policing, and victim services
Criminology and criminal justice programs commonly support these interests. Fresno State’s Corrections, Law Enforcement, and Victimology options show how an applied degree can organize preparation around particular parts of the justice system.
Education alone does not replace employer-specific hiring requirements. Sworn policing typically involves academy, background, medical, and physical standards. Victim-services roles may emphasize case management, communication, community resources, and trauma-informed practice. Correctional work can range from sworn custody positions to rehabilitation programs, research, administration, and policy.
The curriculum should therefore match the function, not merely the agency. Someone interested in correctional program evaluation needs stronger research methods than a person pursuing institutional custody work.
Graduate criminalistics
UC Davis and Cal State LA show what graduate criminalistics expects from incoming students. Both rely on prior scientific preparation, with published prerequisites involving chemistry and quantitative coursework. Graduate school is not an efficient way to avoid undergraduate laboratory science because those courses are usually the starting point for advanced study.
A bachelor’s degree in chemistry, biology, biochemistry, forensic science, or another accepted natural science can provide the base. Undergraduate research, crime-laboratory internships, toxicology placements, and coroner or medical examiner experience can strengthen preparation where available.
What to inspect in a degree plan
Degree names can conceal major curriculum differences. Review the required courses, not only the department description or list of possible careers.
For a laboratory criminalist path
Look for:
- A qualifying physical or biological science major
- General chemistry with laboratory
- Organic chemistry with laboratory
- Quantitative or analytical chemistry
- Biology and biological laboratory work
- Biochemistry
- Genetics and molecular biology
- Physics
- Calculus and statistics
- Instrumental analysis
- Microscopy
- Toxicology or drug chemistry
- Forensic biology or DNA analysis
- Quality assurance and evidence interpretation
- Technical report writing
- Research or substantial laboratory experience
Not every specialty requires every item, but California agencies frequently specify combinations from this list. Quantitative analysis deserves special attention because it appears in the state Criminalist education pattern and can be missing even from science-heavy programs.
For a criminology path
Prioritize:
- Criminological theory
- Research design
- Applied statistics
- Crime measurement
- Qualitative methods
- Survey and interview methods
- Policy analysis
- Policing and courts
- Corrections and punishment
- Victimology
- Race, class, gender, and inequality
- Spatial analysis or geographic information systems
- Data analysis software
- Internship, field research, or community-based work
- Substantial analytical writing
Criminology programs vary sharply in quantitative depth. A student interested in analysis, policy, or graduate research benefits from more statistics and methods than a broad major may require.
For crime scene work
Prioritize:
- Crime-scene photography
- Sketching and documentation
- Evidence recognition
- Evidence collection and packaging
- Fingerprint processing
- Biological evidence handling
- Trace evidence recovery
- Reconstruction
- Chain of custody
- Report preparation
- Moot-court or testimony practice
- Practical exercises using realistic scenes
A forensic studies minor or individual CSI course can add useful context, but a minor with limited chemistry and biology does not create the science foundation required for most laboratory criminalist classifications.
Accreditation has a limited but useful role
The Forensic Science Education Programs Accreditation Commission accredits eligible bachelor’s and master’s forensic science programs, along with qualifying natural or computer science programs that have forensic science concentrations.
FEPAC accreditation can indicate that a forensic program has been evaluated against specialized educational standards. It does not license a graduate, guarantee employment, or replace an employer’s transcript requirements. A California laboratory can still require a specific major, chemistry sequence, or specialty course.
FEPAC is not the proper framework for judging criminology programs. Criminology is a social science field with different curricular goals. Its quality is better evaluated through faculty expertise, methods training, statistics, research opportunities, internship structure, transferability, and alignment with the intended career or graduate degree.
Wording also matters. A university may say that its curriculum meets FEPAC educational standards without holding current FEPAC accreditation. SJSU uses the former wording. UC Davis appeared in a 2025 FEPAC notice as seeking accreditation. Neither statement alone establishes accredited status.
Career outlook and salary data require careful interpretation
The Bureau of Labor Statistics reported a May 2025 national median annual wage of $72,060 for forensic science technicians. It projected 13 percent employment growth from 2025 through 2035, with about 2,800 openings per year nationally. Local and state governments employed most workers in the occupation.
The BLS category combines some scene and laboratory functions that California agencies may separate. It also covers workers at different experience levels and in different regions. The figure is a national occupational median, not a California starting salary or a guaranteed result of completing a forensic science degree.
For sociologists, the BLS reported a May 2025 national median of $106,030 and projected 4 percent growth through 2035. Criminologists can fall within sociology when they conduct professional social research on crime.
The sociologist figure is not a typical salary for everyone with a bachelor’s degree in criminology. Professional sociologist positions usually require at least a master’s degree, and the occupational group is smaller and more graduate-educated than the broad population of criminology graduates. Comparing the two medians does not show that one major “pays more” than the other.
Criminology graduates enter many occupations that BLS tracks separately, including social services, policy, corrections, research support, and justice administration. Their earnings depend on the specific occupation, education level, agency, bargaining unit, region, and experience.
Advice for community college and transfer students
California community college students should plan transfer coursework around the intended upper-division major and career.
A student pursuing criminology, justice studies, or criminal justice may have an established Administration of Justice Associate Degree for Transfer route. Fresno State, for example, identifies transfer similarity between the Administration of Justice AS-T and its Corrections, Law Enforcement, and Victimology criminology options for Fall 2026.
Laboratory criminalistics usually requires a different lower-division plan. Chemistry, biology, physics, calculus, and laboratory sequences are prerequisite chains. Delaying the first chemistry or mathematics course can extend the transfer timeline because later courses must be completed in order.
An administration of justice transfer degree may satisfy lower-division preparation for a justice-oriented major while leaving most of the scientific foundation unfinished. The reverse can also occur: a chemistry student may be well positioned for laboratory eligibility but have little exposure to evidence law, forensic practice, or crime-scene procedure.
The efficient route is to choose the career function first:
- Laboratory evidence analysis: Build the transfer plan around chemistry, biology, biochemistry, or a science-intensive forensic degree.
- Crime research, policy, corrections, or victim services: Use criminology, sociology, criminal justice, or an aligned transfer pathway with strong methods training.
- Civilian crime scene work: Combine scene-processing education with the academic level and practical skills listed by target agencies.
- Sworn CSI assignment: Prepare for the law-enforcement hiring route as well as later specialty training.
- Crime analysis: Emphasize statistics, databases, research methods, geographic analysis, writing, and criminal justice information systems.
A practical decision framework
Use the work product to decide between these fields.
Choose criminalistics or a qualifying natural science if you want to produce laboratory findings from physical evidence. Your education should include the science courses and laboratory experience required to defend those findings technically and, when necessary, in court.
Choose criminology if you want to explain patterns of crime, evaluate policies, study justice institutions, analyze social conditions, or work in corrections, victim services, research, and related public programs. Give preference to programs with serious statistics, research methods, and applied experience.
Choose a CSI-oriented route if you want to document scenes and recover evidence. Make sure the curriculum covers photography, evidence handling, fingerprints, documentation, chain of custody, reports, and practical scene exercises. Then compare that preparation with the hiring model used by the agencies of interest, since California departments divide scene responsibilities differently.
For laboratory work, build the transcript around employer requirements rather than the degree title. California’s state classification and local specifications repeatedly emphasize natural science majors and named courses such as general chemistry and quantitative analysis. A criminology major with a forensic elective remains a criminology education. A science-intensive forensic degree, chemistry degree, or biological science degree is the more direct foundation for criminalist employment.
For social research and justice policy, the reverse applies. Additional chemistry does not replace criminological theory, research design, statistics, crime measurement, institutional analysis, or policy evaluation. A well-designed criminology program develops those abilities more directly.
California students comparing more education and career topics can use the broader CSI Degrees California resources section for related planning guidance. The immediate decision, however, can be reduced to one question: do you want to analyze physical evidence, or analyze crime and society? The answer determines which curriculum deserves priority.
