The Professional Standards Division has primary responsibility for various Human Resources duties. These responsibilities include internal affairs, training, personnel processes for hiring, promotions, and assignments, policies and procedures, detention facility operation and background investigations. The division also has the responsibility for coordinating the city's alcohol and tobacco compliance programs and monitoring complaints involving the city's train whistle quiet zone ordinance. The Division also has primary responsibility for application and compliance with various state and federal grants. The Division Commander is the Deputy Chief of Police and has one Sergeant, one part-time civilian background investigator/property room custodian, one Administrative Services Manager, one Office Services Supervisor, five full-time and four part-time Office Support Representatives (7.3 FTEs).

Internal Affairs
The Division reviews and tracks all inquiries or complaints about Plymouth Police. By policy, all inquiries are classified into one of three categories; complaints, performance matters, or departmental concerns. 

Alcohol and Tobacco Compliance Check Program
Plymouth Police conduct at least two rounds of compliance checks of all establishments within the city licensed to sell alcohol or tobacco products. Plymouth Police train and send out compliance teams of an underage checker accompanied by a plain clothes police officer. The underage checker attempts to purchase alcohol or tobacco products and the officer monitors the transaction. Establishments that fail the checks are subject to administrative penalties that can involve fines and/or suspension of their license for a number of days up to revocation of their license; while the individual who made the sale is also subject to criminal prosecution.

Training
The Sergeant of Professional Standards coordinates the training program for the entire Department.  They ensure compliance with all mandatory training required by the State, including licensing requirements.

Administrative Services
The Administrative Services Division is comprised of all non-sworn personnel in three units; records, communication, and property/evidence.   

Communications
The Administrative Services Manager is also the designated PIO. The city's Communications Manager is the back-up PIO for emergency situations. The two work as a team to handle major incidents. The PIO also provides a weekly incident and arrest report that is available at the front counter of the Public Safety Building, generally on Friday mornings, but is subject to change depending on vacations and holidays.  The position also serves as the designated Responsible Authority under the Data Practices Act for Law Enforcement Data. Under that designation, it is the responsibility of this position to ensure that information is released in compliance with the Law.

Records
The records unit is responsible for handling all 'paperwork' both in hard copy format and electronic format created or maintained. The Supervisor of this unit is also responsible for all statistical information, maps needed and works to analyze data and look for patterns to direct proactive investigations within the community.
