A site-based assessor from the Commission on Accreditation for Law Enforcement Agencies, Inc. (CALEA®), will arrive at the Derry Township Police Department on October 5, 2025 to examine all aspects of our policy and procedures, management, operations, and support services.

We participate in the Advanced Law Enforcement accreditation process which has 463 standards that agencies must comply with in order to gain accredited status. Accreditation is for four years, during which agencies must submit agency status reports and participate in annual remote web-based assessments attesting continued compliance with the standards.

We are extremely proud to be an accredited police agency and have maintained international accreditation through CALEA® since 1997. We are recognized as a CALEA® Meritorious Agency, a designation awarded to agencies who have been accredited for 15 or more years. 

Verification by the assessor that our police department meets the Commission’s comprehensive state-of-the-art standards is part of a voluntary process to gain accreditation; a highly prized recognition of public safety professional excellence. As part of the assessment, agency personnel and members of the community are invited to offer comments at a public information public access portal posted here.

If for some reason an individual cannot access the portal but would like to provide comments to the assessment team, he/she may do so by writing to the Commission on Accreditation for Law Enforcement, Inc., 13575 Heathcote Boulevard, Suite 320 Gainesville, Virginia 20155 or email calea@calea.org.  A copy of the standards is available by contacting Chief Garth Warner at 717-533-5498.
