I dont know how would they arrange a seperate trainig programme for inspestors only. coz the trainig usually lasts for 6 months followed by passing out parade. Their r aroung 500-600 trainees in the ASF academy. Trainees consists of Gaurds(constables), ASI, Inspectors and Deputy Assistant Directors. May be they arrange special short training for the newly appointed inspectors or they may advertise posts of Gaurds and ASI in the near future and call the newly appointed inspectors to join the academy.
As far as the medical test is concerned it is conducted after joining the ASF Academy. Trainees are presented before a board consiting of civil surgeon and other specialist. Height and chest are measured, eye sight is checked and completed blood test is carried out. Trainees having serious heart,lungs or eye problems and hepititis infected are rejected, rest are allowed to continue the training.
If still u have any query . u r welcome to ask
