If you are 18 years-old and not too keen on education you can straight away become a constable. That is only if you have passed your SSC. Of course you have to clear all the physical requirements of a certain height-weight ratio.

To be eligible for the post of assistant sub-inspectors and sub-inspectors you need a degree in any discipline and you should be between the age group of 20-25 years.

Fifty per cent of the vacancies are filled in by direct recruitment and the other half is filled in by promotions from the chief constable level.

In case of non-gazetted officers in the police service, recruitment of officers up to the rank of sub-inspectors, are carried out by the state governments, through selection tests and interviews.

The state public services commission, on the basis of combined service examinations, followed by interviews by the selection board, fill posts of gazetted officers.

IPS officers selected by the UPSC (Union Public Service Commission) are assigned to respective state cadres as assistant superintendents of police and at higher posts.
