Primary schools with less than 200 students were open from the 21st.
As the second phase, all primary sections in schools island wide will be reopen on Monday.
Therefore, the Secretary to the Ministry of Education Prof. Kapila Perera requested parents and teachers to go to schools today and tomorrow and assist in the cleaning work.
However, Secretary of the Ceylon Teachers Union Joseph Stalin told the Hiru news team that the teachers would not be part of the operation to clean the schools.
He added that the teachers will only be engaged in teaching activities from Monday.
