The Trinidad and Tobago Prison Service is currently headed by the Commissioner of Prisons (Ag.) Mr. Dennis Pulchan with assistance from his three Deputy Commissioners. The Commissioner is answerable to the Minister of National Security via the Inspector of Prisons. Each of the Deputy Commissioners is responsible for overseeing one of three streams under which over thirty-five other departments and units fall, with a few exceptions.

These three streams are Administration, Operations, and Programmes. As the names suggest, Administration takes care of the Administrative functions, Operations, includes security and other operational functions, while Programmes department is geared specifically to design and provide programmes and industries in which offenders can participate, with a view towards rehabilitation. This three streamed approach was adopted in 2016 to meet with the challenges of a burgeoning remanded inmate population and the overall welfare of the Service’s efficiency.
