This is the essential supervisor course that every prospective Sergeant should attend. I was previously assigned to a different course which was poorly run and contained largely irrelevant information. This course was taught by current and former police supervisors, contained valuable leadership points, and was tailored to newly promoted supervisors.

J. Harris course was comprehensive and all instructirs had a solid grasp of material and experience being a police supervisor. I highly recommend that all soon to be promoted and current first and mid level supervisors attend this class.

This is my second time attending J. Harris Training. Again, this course did not disappoint and it was more informative than the Supervision Course that is offered at our county police academy. J. Harris goes a lot more in depth on what a Supervisor should know on his or her shift. What decisions to make, how to communicate with your officers, know your police, etc. I would recommend this to anyone who is soon becoming a supervisor.
