  1. Graduation from a regionally accredited college or university or one accredited by the New York State Board of Regents to grant degrees with a Master's Degree or higher in a natural science, forensic science, criminalistics or a closely related field which must have included or was supplemented by a minimum of twelve (12) semester credit hours covering the following subject areas: *biochemistry, genetics, molecular biology and statistics/ population genetics, with at least three (3) of the twelve (12) credit hours being a graduate-level course, and five (5) years of work experience, or its part-time equivalent, in a forensic laboratory performing work equivalent to a Forensic Scientist (Biology).


*Biochemistry, genetics, molecular biology and statistics/population genetics must be the primary component of the classes or courses. Coursework completed with titles other than those listed may demonstrate compliance through submission of a student transcript, letter from a university professor verifying course content or a course syllabus.

NOTE: Education may be substituted for experience as follows: A Doctorate degree (PhD.) in a natural science, forensic science criminalistics or a closely related field may be substituted for two (2) years of the required work experience.



Applicants will be required to undergo a State and national criminal history background investigation which will include a fingerprint check to determine suitability for appointment. Failure to meet the standards for the background investigation may result in disqualification.
