For example, one agency may evaluate the five top scoring candidates, while another agency will evaluate all candidates in the top three whole scores. In most agencies, a candidate who is not selected will remain on the employment list and will be evaluated for other vacancies as they occur. Depending on the position, agencies may require each person selected to fill a position to undergo a medical examination as a condition of employment. The medical examination may include drug screening. For public safety and other selected positions, a psychological examination and background check may also be required as a condition of employment.
Probationary periods are usually six to twelve months.
