Jan Seva Kendra, is an initiative from govt. of India to assist the citizens of India regarding the official process of documentation in relation to their National Identity and other national schemes.
There you get forms for services that are related to your national identity and citizenship benefits. It will definitely include services to procure or make changes to the different certificates like domicile, land, caste, handicap, birth and death certificate, pension for widows etc.
They will also help in procuring ration card, aadhar card, forms for tax and subsidies etc.
But unfortunately this will not include things that falls under the category or department of Education. For any service related to education and its certificate, you have to contact the concerned authority, for example, the board of Education under which the certificate has been issued, the school or college through which you appeared for the concerned examination etc.
To go through the proper channel and have the desired effect, the best procedure will be approaching the Education Department through the associated institution, as they will know the correct procedure.
As this change will be directly related to your identity, you must have heard this rumor about Jan Seva Kendra. but that is not a valid information. For any change of fact on the educational certificates, you have to contact the UP Board of Education. To make things easier, you can shoot an email at firstname.lastname@example.org or call on 9568259845, seeking help for your issue.
Make sure you furnish them will all the necessary documents that will be required to establish your identity in support of the changes you want to make in the certificate.
