Urging teachers to teach students morals, values and ethics, Vice President M. Venkaiah Naidu on Tuesday advised educational institutions to make social service mandatory for their wards.

"Make social service or service to armed forces or voluntary organisations like National Service Scheme (NSS) and Scouts & Guides mandatory for conferring degrees," said Naidu at a function here. Addressing the valedictory function of the V.P. Deenadayalu Naidu's centenary celebrations here, Naidu said social services would help students inculcate the spirit of oneness, nationalism and social consciousness.
