The most serious gap in training is found in the matter of in-service courses that affords an opportunity to spend some time in retrospection and also in promotion courses. Rarely does a constable get a chance to attend a training course after initial training in most of the States for updating "Kash" to meet the present day challenges more professionally. The situation is only marginally better for subinspectors and in more recent times, somewhat better for DSPs and IPS Officers. Even in the existing courses, the content, duration and purpose is not well defined or focused. These yawning gaps have to be filled by designing a comprehensive package for each level with periodical updating of the same. 

In Tamil Nadu, In-Service Training Centres, sanctioned in the year 1976, are eleven in number one in each of the range headquarters headed by a DSP. The police personnel from the rank of Constable to DSsP and there is a training policy to train one-fifth of the police force. The functioning of In-Service Training centres is supervised by the Deputy Inspector General of Police, Training. For updating the "KASH" of senior officers, the Government have created a fund - " Twenty Lakhs Revolving Fund" for organising every year one National Workshop; five capsule courses for senior officers; 10 capsule courses for DSsP & Inspectors at PTC; Two courses each at the eleven range headquarters apart from organising essay and elocution competition among students on one of the police subjects for 'policeimage building' exercise and in addition a debate among police personnel on one of the subjects on human rights as per the suggestion of NHRC. It is informed that the target of training one fifth of the existing strength of police was achieved.

As far as the promotion courses, well-planned training modules have been developed for each rank and unless officers attend and get through their examinations they would become ineligible for promotion to the next rank.
