For each category of tasks that must be explained or demonstrated, there is a "critical task sign-off" sheet that must be signed by both the training sergeant and the trainee to indicate that each orientation task has been covered. Tasks pertinent to the custodial office are grouped under the topics of orientation (office equipment and operations), reports, files and manuals, and personnel scheduling. Tasks associated with the custodial facility are functional supervision, general segregation, juvenile detention, duration of detention, strip searches, involuntary blood tests, ibars, deaths and injury in custody, facility emergencies, jail van use, and misdemeanor booking policy. Orientation tasks for field operations are classified as general, reserves, the supervisor unit, specific field operations, mutual aid, police collisions, pursuits, and employee injuries. Other task categories are forms, resources, philosophies, field training officers, use of the K9 unit, and communications.
