All law enforcement officers in Kentucky, (except as listed below), hired after 1998 are required to complete the minimum screening, physical training and classroom requirements of the Kentucky's "Police Officer Professional Standards (POPS)" prior to being certified, and acting, as a law enforcement officer. Larger agencies, such as the Kentucky State Police, as well as the Louisville Metro Police and the Lexington Division of Police, operate their own police academies and may have requirements that exceed the minimum POPS standards. Agencies in Kentucky who do not run their own academies send their prospective officers to a 20-week basic training class at the Kentucky Department of Criminal Justice Training Academy, operated by the Kentucky Justice and Public Safety Cabinet and located on the campus of Eastern Kentucky University in Richmond. Exceptions to POPS training and certification are officers hired prior to 1998 and elected law enforcement officers whose duties and requirements are set forth in the Kentucky Constitution. These include sheriffs, constables, coroners and jailers, (though generally not deputies). Many of these officeholders, however, hold POPS certification from previous employment as law enforcement officers prior to their election and some will receive POPS certification or approved equivalent training before taking office.
