@Riya chatterjee M.Phil, or Ph.D. is not a mandatory degree for school teachers. Hence, this sort of degrees or diplomas has not been provided any provision in case of acquiring professional degrees on deputation except B.Ed. Even M.Ed. does not enjoy the privilege of being granted permission to acquire on deputation in case of school teachers. So, one school teacher will have to manage on his own to pursue M.Phil, or Ph.D., or even M.Ed.
