When a city has a vacant slot(s) to fill for a police officer, the city requests a list of candidates from the Civil Service Board. Based on the number of slots a list is sent to the city. The city notifies those on the list to come in and sign that they will accept an appointment and to receive a city application. After completion of the applications, a background check is conducted and the final candidates are brought in for an interview. All candidates selected must attend and complete a Massachusetts Criminal Justice Training Council Police Academy.
