know the educational qualifications

Educational qualifications are being treated as 'Personal information" and as disclosing such details amounts to the invasion of privacy of persons, one can not get the qualification.  Even if it is for PM or HRD Minister same rules apply.  However, if you have bonafide information that someone has secured employment/admission through fake certificates, first you have to make a complaint on the basis of prima facie evidence.   Wait for a month and then file an RTI application seeking information on larger public interest, as such employment/admission was secured at the cost of a more qualified candidate and through cheating by means of a fake certificate.  Such information then must not be denied.

Why on earth you wish to know the educational qualifications of an en Employee?!!

Educational Qualifications are the personal information of an individual.  Even if you approach under the RTI Act, he is not obliged to provide you the information as it is personal details and Department concerned also may not disclose this information for the simple reason that they are not under obligation to disclose personal information of their employees in terms of the RTI Act although the same details may be with them based on which they might have given the job/promotion etc.

What are the facts? What is the context?
