How To Verify Educational Documents Of A New Joiner

Dear Seniors,
One of my friend has joined a start-up organisation as as AM-HR in Punjab and being as a small organisation he need assistance in situation.
Please suggest on How to verify educational documents of a new joiner without taking help from Agencies ?

Dear Mr Sam
You can refer the certificates to the Boards/Universities which issued them and verify their genuineness. You can also write to the College/school in which the individiual studied last for verifying the genuineness.
With regards
