May be authorized to perform administrative review of casework. Performs other duties as assigned.
Under general supervision, Forensic Scientist II (FS II) performs more complex and difficult casework in Comparative Analysis, communicates independently with investigators, Deputy District Attorneys and defense attorneys, prepares documentation and written reports, and presents finding in court. May be authorized to perform technical review of casework. Performs other duties as assigned.
Under direction, Forensic Scientist III (FS III) is the lead worker and performs the most difficult and complex casework in Comparative Analysis, communicates independently with investigators, Deputy District Attorneys and defense attorneys, presents findings in criminal court, prepares documentation and written reports. Will be authorized to perform technical review of casework. Performs other related duties as assigned.
Distinguishing Characteristics:
The Forensic Scientist Trainee classification differs from the Forensic Scientist I in that this classification is required to successfully participate in a forensic science training program. Throughout the training program, the Trainee will be required to demonstrate competence in one or more assigned specialty areas before being eligible to promote to the Forensic Scientist I level.
The Forensic Scientist I classification is characterized by the performance of professional forensic science analysis. Incumbents are not expected to have expertise in a complex specialty area. This classification differs from the Forensic Scientist II classification in that the latter classification is expected to perform journeyman-level analysis and casework. Incumbents in this classification typically receive mentoring as they continue their professional development in a specialty discipline.
The Forensic Scientist II classification is the journeyman-level classification in the forensic scientist series. This classification is characterized by its thorough knowledge of forensic science in at least one specialty area of the lab. Trains other forensic scientists in specialized knowledge and work methods.
The Forensic Scientist III is the advanced journeyman-level classification in the forensic scientist series. It differs from the Forensic Scientist II in that this classification provides lead direction on more complex, difficult, and highly visible cases. It differs from the Supervising Forensic Scientist in that the latter classification has full supervisory responsibility over a section of the forensic science laboratory.
