Hi

Jharkhand state open school is very much functioning https://www.jsos.ac.in/Contact.aspx

You can check it's official website. It's even approved by university grants commission and government of India. If there was a problem with its accreditation it might have been to come to Indian government notice by now with the advanced internet reach. But it's website is still open it's even showing UGC and government of India Badge in its website.

Hope answers your query!
