The Police Department was originally accredited by the Commission for the Accreditation of Law Enforcement Agencies (CALEA) in 2004, and was reaccredited in 2007 and 2010. The department has to perform a self-assessment and undergo an on-site assessment by CALEA evaluators.
After a rigorous self-assessment, which can take two to three years, agencies invite CALEA-trained assessors for an on-site visit. They determine an agency's compliance with standards, view agency operations and conduct a public information session with residents.
During its three-year accreditation cycle, an agency must maintain compliance with applicable standards, keep its proofs of compliance up-to-date and live by the letter and spirit of those standards. To retain its accredited status, an agency is required to submit to CALEA annual reports.
