Hi

LEAVE

A trainee earns leave at the rate of one–sixth of the period actually served by him. Leave due is ordinarily granted, if reasonable notice has been given by the trainee to his MIT / Principal.

In order to prepare for the examinations of the Institute, a trainee is granted leave for a period of 2 months or to the extend of leave due, whichever is less. However, the trainee should make an application for such leave at least 15 days in advance. The days on which a trainee appears for the examination conducted by the Institute (including intervening holidays) are counted as a period on duty.
