Forensic examiners, at a minimum, need a bachelor's degree in a related field to qualify for entry-level employment. With that in mind, it can take about four to five years or more to become a forensic examiner. If you already work in a law enforcement field and want to learn about digital forensics to enhance your skills, you can complete a certificate that may help you advance into that sector. You can complete our online Forensic Computer Examiner Certificate in as little as 6-10 months.
