National schools come under the direct control of the Ministry of Education and therefore have direct funding from the ministry. Most of these schools were established during the colonial period and therefore are established institutions. These few are referred to as famous schools or elite schools since they have a rich history and better maintained facilities than the average public school. This is mainly due to the support of their alumni. In recent years newer schools and several central colleges have been upgraded to national schools from time to time, thereby making the total number of national schools 350.
