Police trainers train probationary, new academy recruits, or cadets, and seasoned veterans on the theory and practice necessary to become a police officer. They conduct theoretical lectures on academic subjects such as law, government regulations, community relations and human diversity. Police academy instructors also provide more hands-on, practical instruction regarding physical training, the care of firearms, first aid, self defensive tactics and vehicle operations. They also prepare and develop lesson plans and new training programmes as new law enforcement-related regulations and issues arise. The instructors monitor the students' progress, evaluate them individually and prepare performance evaluation reports.
