Steps for Becoming an Evidence Technician

Evidence techs must have a minimum of a high school diploma, but many departments prefer to hire candidates who have a bachelor’s degree in addition to previous experience working in law enforcement. Many evidence custodians and forensic evidence technicians have certificates or degrees in criminal justice with a focus on criminal forensics, constitutional law, or statistical research and analysis. Specific classes may include Criminology, Sociology, Biology, and lab work that provides training in the use of computers and specialized equipment like microscopes, centrifuges, and other devices. Many criminal justice schools provide opportunities for students to volunteer or intern in real-world work environments. The steps to become an evidence tech below are general and will vary by job:

  1. Attend a degree program or gain experience in a related field.*
  2. Apply for an evidence technician position.
  3. Attend an interview.
  4. Successfully complete a criminal history background check, fingerprint check, drug test, and a polygraph examination.
  5. Get hired as an evidence technician.
  6. Receive on-the-job training once hired.

*Though a degree is not necessary to obtain a job as an evidence technician, many applicants will pursue one to make themselves more competitive in the market, especially if they do not have previous experience in criminal justice.

Evidence Technician Job Training

Newly hired technicians generally must complete on-the-job training under the direct supervision of a senior evidence technician until they have gained the experience necessary to work on a more independent basis. Employers may also require evidence technicians to have certification. The International Association for Property and Evidence, Inc., for example, offers the Certified Property and Evidence Specialist credential.

Other Helpful Skills and Experience

Prospective evidence technicians should have strong communication skills in order to effectively testify in court and write concise and meaningful reports. Successful candidates must be able to work independently without direct supervision and possess the ability to prioritize multiple assignments and ongoing projects.
