vPublic schools are administered by the government. The private sector comprises schools run for profit and fee-paying non-profit schools which are often run by charitable organisations — especially by Catholic diocesan and religious orders that operate over 300 large elementary/secondary schools throughout the country.[4][citation needed] Village and sub-district schools usually provide pre-school kindergarten (anuban อนุบาล) and elementary classes, while in the district towns, schools will serve their areas with comprehensive schools with all the classes from kindergarten to age 15 and separate secondary schools for ages 13 through 18.
