The Criminalist job family has five levels which are distinguished by type and complexity of work and the degree of responsibility assigned.

Level I:     
This is the entry level where incumbents train to perform forensic analysis, and perform some limited supervised casework.  All aspects of assigned tasks are clearly defined and all work is technically and administratively reviewed during performance and upon completion.  At this level, incumbents may accompany senior analysts to crime scenes and perform tasks under direct supervision. Incumbents do not have supervisory, research and development, or training responsibilities.

Level II:     
At this career level incumbents perform a range of basic work as a forensic laboratory analyst.  They perform scientific and technical analysis in all but the most difficult and complex criminal cases.  They train to perform more advanced and complex analysis.  They may assist in training others in basic work, perform limited technical and administrative reviews, and perform limited supervised research and development, and may assist in crime scene work.

Level III:     
This is the specialist level where incumbents independently plan and perform advanced scientific and technical analysis of evidence in criminal cases, including the most complex and difficult of examinations requiring extensive knowledge and high skill levels.  They are individually responsible for the accuracy, sufficiency, and timely completion of their work.  Incumbents may train other criminalists, function as lead worker by assigning/reviewing work of others, conduct research and scientific studies to develop new techniques and methods, assist in writing technical protocols and laboratory procedures, and may serve as unit or regional supervisor in the absence of the supervisor.  Incumbents at this level may independently process crime scenes.

Level IV:     
This is the leadership level where employees are assigned responsibilities supervising and directing others in work involving the scientific and technical analysis of evidence and/or convicted offender DNA samples.  They supervise the personnel and activities of a forensic laboratory unit or region; provide general direction of the unit or region; provide technical management over a specific discipline in a unit or region; and/or they may function as a technical manager over a forensic discipline practiced at one or more laboratories.  They will assist with budget preparation, quality audits, quality assurance, laboratory planning, laboratory projects, grants, training and development, developing specifications for acquisition of specialized equipment or supplies, and in developing/revising operational and technical policies and procedures.  They also perform some forensic analysis of evidence and/or offender DNA samples, and may process crime scenes
