The Commission on Accreditation for Law Enforcement Agencies, Inc. (CALEA) was formed to develop a set of law enforcement standards and establish and administer an accreditation process by which law enforcement agencies at the State and local levels can demonstrate voluntarily that they meet professional criteria. The overall goal of the accreditation program is to improve the delivery of law enforcement services from coast to coast.
The Willowbrook Police Department was originally awarded accredited status in Savannah, Georgia on November 16, 1991. The Department received the Meritorious Award for accreditation and was awarded re-accredited status for the ninth time at the November 2017 Commission meeting in Frisco, Texas.
