Hi,

The Jharkhand state open school(JSOS) is a valid board. It is a recognized board under the government of Jharkhand.

Board website: https://www.jsos.ac.in/

You may have visited the website of Jharkhand state open school which is a different organization with a similar name.

However, this organization was declared invalid by Allahabad high court in 2020.  The Lucknow bench of Allahabad high court declared this organization a bogus and fictitious organization.

So, the JSOS is a completely valid board.

Thanks!
