DIMAPUR, MARCH 16 (MExN): The Naga Students’ Federation (NSF) today called for specific changes in education policies of the state and called upon the Nagaland State School Education Department to intervene. In a letter to the Director, School Education Department, the NSF observed that while there is are an excess number of teachers in some schools, there are also many schools without adequate teachers. It asked for a stop to all transfers and posting of teachers in the middle of the academic session. It also demanded appointment/deployment of teachers in the schools where there are no adequate teachers. The NSF then called for a review of the powers and functions of the Village Education Committee (VEC).
