Professional Standards Unit

The Professional Standards Unit provides personnel services to the Sheriff’s Office’s more than 300 employees.


These services include: Recruitment; pre-employment testing; polygraph and computer voice stress analysis testing; hiring; maintenance of personnel records; assistance in developing and coordinating promotional examinations; managing worker’s compensation claims; insuring compliance with federal and state mandated laws and programs; investigation of all complaints against staff; developing and implementing lawful personnel practices; managing the performance evaluation system; and serving as the primary liaison with the County’s Human Resources Department, Risk Management and Worker’s Compensation providers.

In addition, we are responsible for satisfying the training needs of the entire department and are responsible for the development, certification and presentation of a vast majority of in-service training which is presented to sworn members of the department, as well as many officers from allied agencies. This is achieved in conjunction with The State of California, Peace Officer Standards and Training (POST) and the State of California, Board of Corrections (STC). This training is provided to every sworn member by providing a minimum of 48-hours of advanced officer training annually through in-service training. Areas of training include perishable skills such as firearms, use of force, emergency vehicle operations, and arrest and control tactics.
