Hello,


The Purvanchal Board of Secondary Education is not a valid board. It is am autonomous body of Purvanchal Shiksha Parishadwhich is established for development of education under the guidelines of national education policy 1986 Govt. of india. and programme of action 1992 Govt. of India.
It has been constituted to regulate non formal Primary, Middle, Secondary (10th ), Senior Secondary (12th ) education and other vocational courses ( Under Self Employment Education Scheme) in India . It's aim is to provide education and to educate uneducated boys, girls, men and women to upliftment the literacy in india.

I hope this helps.
