Becoming a criminalist is a science-focused career decision, not just a criminal justice career choice. Criminalists help investigators understand what physical evidence can—and cannot—prove by examining DNA, firearms, fingerprints, trace materials, toxicology results, and other evidence in a lab or crime scene context.
This guide is for students, career changers, and working criminal justice professionals who want a realistic view of the path into criminalistics. You will learn what criminalists do, which degrees are most useful, how long training can take, what certifications may help, how much the career can cost, and whether the salary and job outlook justify the investment.
Quick answer: Is becoming a criminalist a good career path?
Criminalists earn a median salary of $68,152, and high earners can make up to $127,000 per year.
Forensic science technician employment is projected to grow 14% from 2023 to 2033, which is much faster than the average for all occupations.
Experienced criminalists can move into roles such as forensic laboratory supervisor, forensic lab director, crime scene investigator, specialized forensic analyst, or forensic science educator.
A criminalist is a forensic science professional who uses laboratory methods and scientific reasoning to examine physical evidence connected to crimes. Their work may involve DNA, firearms, controlled substances, fingerprints, blood patterns, trace materials, glass, fibers, or other evidence that can help investigators reconstruct events or link evidence to people, places, or objects.
Although a criminology degree may sound like the obvious route, many criminalist positions require stronger preparation in biology, chemistry, forensic science, or another natural or physical science. Criminology is valuable for understanding crime, justice systems, and social behavior, but criminalistics is usually more lab-centered and evidence-centered.
Criminalists may work for state or local forensic laboratories, law enforcement agencies, medical examiner offices, federal agencies, or private forensic consulting firms. According to the Bureau of Labor Statistics, forensic science technicians, a category that includes criminalists, held approximately 18,600 jobs in 2023. Employment is projected to grow 14% from 2023 to 2033, much faster than the average for all occupations.
What do criminalists do day to day?
Criminalists translate physical evidence into scientifically supported findings. Some spend most of their time in laboratories, while others also visit crime scenes, document evidence, or testify in court. The exact duties depend on the employer and specialty.
Duty
What it involves
Why it matters
Evidence collection and preservation
Collecting, packaging, labeling, and protecting materials such as biological samples, fibers, firearms evidence, or trace evidence.
Poor handling can compromise evidence and weaken a case.
Laboratory testing
Using methods such as DNA analysis, toxicology testing, drug identification, microscopy, or ballistic examination.
Scientific results can support or challenge investigative theories.
Crime scene reconstruction
Interpreting evidence patterns to understand possible sequences of events.
Reconstruction helps investigators evaluate what likely happened and what claims are consistent with the evidence.
Documentation and reporting
Writing clear reports that explain methods, findings, limitations, and conclusions.
Reports must be understandable to investigators, attorneys, judges, and juries.
Expert testimony
Explaining scientific findings in court and answering questions about methods and conclusions.
Criminalists must communicate accurately without overstating what evidence proves.
Collaboration with investigators
Working with detectives, attorneys, and other personnel to clarify evidence questions.
Good communication helps ensure the right tests are performed and interpreted appropriately.

How do I become a criminalist for 2026?
The most reliable path to becoming a criminalist is to build a science-based academic foundation, gain hands-on lab experience, and then meet the hiring standards of forensic laboratories or public agencies. Criminalistics is competitive, so coursework, internships, and technical competence matter.
Earn a relevant bachelor’s degree. Most employers prefer or require a bachelor’s degree in forensic science, chemistry, biology, or a related physical science. A science-heavy curriculum is usually stronger than a general criminal justice curriculum for laboratory roles.
Choose courses that match forensic lab requirements. Prioritize chemistry, biology, molecular biology, statistics, instrumental analysis, toxicology, genetics, and quality assurance when available.
Build laboratory experience before graduation. Look for internships, research assistant roles, forensic lab practicums, or volunteer opportunities with public agencies. Practical evidence-handling experience can separate you from applicants with only classroom training.
Consider graduate study if you want specialization. A master’s degree may improve your competitiveness for advanced work in DNA, toxicology, forensic chemistry, or leadership roles, though not every entry-level job requires one.
Pursue certification when it fits your role. Credentials from recognized organizations, such as the American Board of Criminalistics, can demonstrate professional knowledge after you meet eligibility requirements.
Keep learning after you are hired. Forensic methods, quality standards, digital evidence, laboratory automation, and courtroom expectations continue to evolve, so continuing education is part of the career.
A cheap online criminal justice degree may help students who want broader justice-system knowledge or need a flexible route into related roles. However, for traditional criminalist jobs, online or campus programs with substantial science coursework and laboratory training are generally a better fit.
What skills and experiences are important for criminalists to have?
Criminalists need more than an interest in crime solving. The work requires scientific discipline, careful documentation, ethical judgment, and the ability to explain technical findings without exaggeration. A single error in handling, testing, or reporting evidence can affect an investigation or court proceeding.
Skill or experience
Why it matters in criminalistics
How to build it
Scientific knowledge
Criminalists must understand chemistry, biology, physics, and laboratory methods used to examine physical evidence.
Choose a science-based major and complete lab-intensive courses.
Analytical reasoning
Evidence often has limits. Criminalists must interpret results logically and avoid unsupported conclusions.
Take statistics, research methods, and advanced lab courses.
Attention to detail
Small mistakes in labeling, measurement, or documentation can compromise evidence.
Practice strict lab note-taking and chain-of-custody procedures.
Written communication
Reports must be precise, clear, and defensible in legal settings.
Write lab reports, request feedback, and study forensic report formats.
Courtroom communication
Criminalists may need to explain scientific findings to people without technical training.
Take public speaking, mock trial, or expert testimony workshops if available.
Technology competence
Digital evidence, lab information systems, and automated tools are increasingly part of forensic work.
Learn database tools, digital evidence basics, and lab software.
Field or lab exposure
Employers value candidates who understand real evidence workflows.
Pursue internships, practicums, agency volunteer work, or research roles.
A computer science major can be useful for students interested in digital forensics, cybercrime investigations, or evidence involving devices and networks. For conventional wet-lab criminalistics, however, biology, chemistry, forensic science, or a related physical science usually provides the more direct preparation.
What licenses and certifications do I need as a criminalist?
Most criminalists do not need a universal national license, but requirements vary by state, employer, laboratory, and evidence discipline. Some jurisdictions require formal licensing for forensic analysts, while many employers use internal qualification standards, proficiency testing, training records, and quality assurance requirements.
Licensing and certification can also support related investigative careers. For example, people exploring the CIA officer career path may find that forensic, analytical, scientific, or cyber-investigative experience strengthens their profile, depending on the role.

How Does Choosing an Accredited Forensic Science Program Impact My Career?
Accreditation helps you judge whether a forensic science program meets recognized academic and professional standards. For students pursuing criminalistics, this matters because employers may look closely at coursework, laboratory training, faculty expertise, internship access, and whether the program prepares graduates for forensic laboratory expectations.
Accreditation does not guarantee a job, but it can reduce risk when comparing schools. It is especially important if you plan to apply to competitive forensic laboratories, pursue graduate study, or seek credentials later. To compare academic options, review Research.com’s guide to colleges with the best forensic science programs.
Questions to ask before choosing a forensic science program
Is the program accredited, and by whom?
How many chemistry, biology, statistics, and laboratory courses are required?
Does the program offer internships with forensic laboratories, law enforcement agencies, or medical examiner offices?
Are courses taught by faculty with forensic laboratory or courtroom experience?
Does the curriculum align with the job postings you plan to target?
What are the total costs, including lab fees, housing, books, and supplies?
How does the program support career placement, resume preparation, and interview readiness?
What distinguishes specialized law enforcement roles from conventional criminalist careers?
Specialized law enforcement roles often combine investigative authority, legal procedures, field operations, and sometimes tactical or security responsibilities. Criminalists, by contrast, are usually focused on scientific evidence analysis, laboratory methods, documentation, and expert testimony.
Some professionals blend both paths. A person with forensic science training may later move into specialized investigative work, while law enforcement professionals may add forensic training to strengthen evidence-based decision-making. For example, people exploring ICE agent qualifications should expect a different mix of legal authority, agency training, fieldwork, and federal hiring standards than a laboratory criminalist would face.

Studying while working was difficult, but the flexibility of online coursework helped me stay employed and still pursue forensic training. Getting internship experience early made the transition into a crime lab much easier.Chris
Are there lucrative career opportunities beyond the traditional criminalist role?
Yes. Criminalists and criminal justice graduates can sometimes move into higher-paying or more specialized work, especially when they combine evidence expertise with leadership, digital forensics, consulting, cybercrime, financial investigations, or advanced education. The strongest opportunities usually go to professionals who can document technical competence and communicate findings clearly to non-scientific audiences.
If you want to compare alternatives, Research.com’s guide to the highest paying jobs you can get with a criminal justice degree can help you evaluate roles that may offer stronger compensation, broader leadership options, or different education requirements.
How is technology transforming criminalist practices?
Technology is changing criminalistics through digital forensics, laboratory automation, artificial intelligence-assisted workflows, improved databases, and more sophisticated analytical instruments. These tools can help laboratories process information more efficiently, but they also raise expectations for technical literacy, validation, quality control, and transparent reporting.
Criminalists should not assume that technology replaces scientific judgment. Instead, modern tools make it more important to understand method limitations, error rates, documentation standards, and how to explain results clearly in court. Students comparing broader criminology degree jobs should note that technology skills are becoming useful across investigations, crime analysis, corrections, and forensic roles.
Can online forensic science programs boost career advancement in forensic science?
Accredited online forensic science programs can support advancement when they match your career goal and include appropriate science coursework, laboratory components, and credible faculty support. They may be especially useful for working professionals who need flexibility while building forensic knowledge.
However, students should be cautious. A fully online program may not satisfy every employer’s laboratory expectations if it lacks hands-on science training. Before enrolling, ask how the program handles labs, internships, transfer credits, career placement, and preparation for certification or licensing requirements in your state.
Common mistakes to avoid when preparing for a criminalist career
Choosing a degree based only on the title. A program called forensic science is not automatically strong. Review the actual coursework, lab hours, faculty background, and internship access.
Assuming criminal justice and criminalistics are interchangeable. Criminal justice degrees can be useful, but many criminalist jobs require chemistry, biology, or forensic science preparation.
Ignoring accreditation and employer requirements. Always compare program requirements with real job postings from forensic labs or agencies.
Focusing only on tuition. Housing, fees, supplies, transportation, books, and lost income can change the real cost of a degree.
Waiting too long to get experience. Internships, research, and lab assistant roles can be crucial in a competitive applicant pool.
Collecting certifications without a strategy. Certifications are most valuable when they match your specialty, experience level, and employer expectations.
Assuming salary outcomes are guaranteed. Pay depends on location, agency budgets, role type, seniority, education, and specialization.
Criminalistics is a science-first career. A bachelor’s degree in forensic science, chemistry, biology, or a related physical science is usually more useful than a general criminal justice degree for lab-based roles.
The career outlook is favorable: forensic science technician jobs are projected to grow 14% from 2023 to 2033, and criminalists earn an average salary of $68,152, with top professionals making up to $127,000 per year.
Education costs can be substantial. A four-year forensic science or related bachelor’s degree can cost between $108,584 for a public in-state option and $226,512 for a private option, so comparing net price and transfer options matters.
Licensing is not universal, but it can matter by state. Texas forensic analyst licensing costs $220, while American Board of Criminalistics certification costs $350.
Online programs can help, but only if they match the role. For criminalist jobs, verify science labs, internships, accreditation, and employer acceptance before enrolling.
The best candidates combine lab competence, evidence-handling discipline, clear writing, courtroom communication, and continuing education in forensic technology and quality standards.
