In August 2006, the Greenbelt Police Department underwent an extensive on-site assessment by a team of three specially trained assessors from the Commission on Accreditation for Law Enforcement Agencies (CALEA). Upon completion, of the assessment the department was found to be in compliance with the 446 standards of professional excellence set forth by CALEA. In November 2006, in Reno, Nevada, the department received full unconditional accreditation from CALEA. This was the culmination of three years of intense self-assessment by the department.
CALEA accreditation runs in three year cycles, the department is currently reevaluating every policy and procedure against CALEA’s new 5th edition of standards. In March 2007, the department’s accreditation manager was selected and trained by CALEA to assess other departments seeking initial or re-accreditation status.
