The PDET 400 series was designed to assess whether candidates have the competencies to perform successfully at the rank of detective in a law enforcement agency. PDET 401 and 402 each contain three subtests, which are listed below along with examples of some of the competencies they assess.

  1. Police Investigative Procedures. Knowing the procedures and techniques of criminal investigations (e.g., interviewing and interrogating, surveillance), and the proper procedures for documenting, gathering and preserving evidence is critical for detectives. (29 items)

  2. Laws Related to Police Work. This subtest will make sure your candidates know what constitutes probable cause; the laws and rules of evidence; and the laws and procedures of detention and arrest, interviewing and interrogation, and search and seizure. (37 items)

  3. Concepts for Writing & Completing Reports, Records and Paperwork. Your agency could win — or lose — a case based on whether or not your detectives can write in an accurate, clear, concise, and organized manner, as well as their knowledge of the principles and techniques for accurately completing crime reports, arrest reports and warrants.
