The purpose of CALEA's Accreditation Programs is to improve the delivery of public safety services by:
- Maintaining a body of standards (covering a wide range of up-to-date public safety initiatives) developed by public safety practitioners
- Establishing and administering an accreditation process
- Recognizing professional excellence
The Maryland-National Capital Park Police, Prince George's County Division received international accreditation from CALEA in 2002 and was re-accredited in 2005, 2008, 2011, 2014, 2017, and 2021. Each accreditation achievement was attained after a comprehensive three-year review of the division's operations, equipment, policies, practices and procedures. The accreditation process allows a law enforcement agency the opportunity to voluntarily demonstrate conformance and compliance with established standards that promote professional excellence.
