Each sworn officer for the Sidney Police Department must within one year of service attend the Montana Law Enforcement Academy located in Helena, Montana.  The 12-week academy instructs officers in all facets of law enforcement from general patrol functions to crime scene management.

In addition to academic requirements, officers attending M.L.E.A. must meet strict physical standards. Upon completion of M.L.E.A., successful graduates receive a Certificate of Completion. The total number of training hours are credited to individual officers who apply for certification through the Montana P.O.S.T. Council.

After initial training, officers may attend other specialized training through M.L.E.A., both at the academy itself or through regional training schools sanctioned by M.L.E.A. and P.O.S.T.  Additional training hours enable officers to apply for more advanced certificates, such as Intermediate, Advanced, Supervisory and Command Certification.
