The IS will assess the teachers' knowledge in the field of Sharia or Islamic Law, during the schools' closure.
Sources said the IS held a meeting Wednesday in one of the mosques in al-Mayadin town with the school principals to inform them of the decision.
The radical organisation is to provide an Islamic law course for the teachers in al-Mayadin in order to prepare them for applying the new curriculum, SOHR said.
A group of students, teachers, and parents protested near Deir al-Zor against the closing of the schools.
The jihadis control almost the entire province of Deir al-Zor.
