An applicant who wishes to apply for any post shall click ‘APPLY’ against the post notified in the Commission’s website and use the same User ID and Password given for One Time Registration. One Time Registration is not an application for any post.

One Time Registration is valid for five years from the date of registration. After completion of five years, the applicant must renew the One Time Registration by paying the fee prescribed

One Time Registration is only collection of certain basic information of the applicant. It is entirely different from the application for any direct recruitment.

(For example: An applicant has to submit a separate application each for Group II and Group IV, if he/she intends to apply for both).

Use the “Forgot User ID” / “Forgot Password” link available in the home page of the Commission website and furnish the required information to retrieve the Login credentials.

The details furnished / options selected by the applicants in the online application can be edited till the last date for submission of the online application.

Candidates with benchmark disability shall be permitted the service of a scribe upon making such request in their online application. Requests for scribes made after the submission of application or on the date of examination will receive no attention.
