The primary objectives of the services are two-folded :

To ensure continued care and guidance, statutory supervision are provided for persons released from training, rehabilitation, detention and drug addiction treatment centres. The rehabilitation staff on supervision duties, with the support of the families of inmates, establish sound rapport with the inmates and prepare them to face the challenges and demands to be expected on their return to the community. Continuous contact is maintained with every inmate in the penal institution, and close supervision continues after release through regular visits made to the discharged inmates' home or place of work.

Success rate for the supervision programmes is measured by the percentage of supervisees who complete statutory supervision without reconviction. In the case of drug addiction treatment centres, the supervisees must also remain drug free.
