Most of the schools in Macau are private or subsidized schools. As of the 2015-2016 school year, there were 74 primary and secondary schools that provided formal education, including ten public schools and 64 private schools. Of the schools all but ten were a part of Macau's free education network. many of the schools in Macau are operated by Catholic organizations. A basic 15 years compulsory, free education, is offered to those pupils who have been enrolled at the schools which have met certain requirements stipulated by the government.
