Hajia Zainab Bello, the Director of Quality Assurance in the Ministry of Education and Human Capital Development, said apart from being illegal, the schools were operating in unhygienic environment.
Bello, who spoke on behalf of Alhaji Musa Yeketi, State Commissioner for Education and Human Capital Development while closing 19 other private schools, said government had begun verification of tertiary institutions in the state.
She said the objective of the exercise was to fish out those violating the laws that established them.
Bello said the government had previously shut down schools which were either built with wooden planks or operating without due authorisation from the state government.
The director said the state government is commitment to ensuring quality education, stressing that government would continue to close private schools operating illegally.
