Fifty nine jos prison inmates graduate adult education scheme programme
That's a great achievement! Here's a rewritten version with a more formal tone:
"Fifty-nine inmates at Jos Prison have successfully completed the Adult Education Scheme Programme, marking a significant milestone in their personal and educational development. This accomplishment demonstrates the effectiveness of the programme in providing inmates with the skills and knowledge necessary to reintegrate into society upon their release. The programme's success is a testament to the dedication and hard work of the inmates, as well as the support and guidance provided by the prison authorities and educators involved."
