Commission on Accreditation for Law Enforcement Agencies (CALEA)

  
 On July 31, 1993, the Pennsylvania State Police was accredited by the Commission on Accreditation for Law Enforcement Agencies (CALEA), thus becoming the largest internationally accredited law enforcement agency in the world.
Accreditation facilitates the creation, verification and maintenance of high quality policies and procedures, via voluntary compliance with a body of performance standards.

CALEA agencies continually self-evaluate policies and procedures to maintain compliance with over 450 applicable standards. They submit their policies, procedures, personnel, installations and equipment to CALEA on-site inspections every three years.

CALEA allows it agencies to participate in determining and establishing standards that address changing issues facing police professionals.  Its standards require agencies acknowledge policy issues, but do not dictate how to address them allowing each agency to determine the method to best meet the needs of the citizenry and the Department. A study has indicated accredited law enforcement agencies are better able to defend themselves and their personnel against lawsuits.
