Passage: In the final years of the apartheid era, parents at white government schools were given the option to convert to a 'semi-private' form called Model C, and many of these schools changed their admissions policies to accept children of other races. Following the transition to democracy, the legal form of 'Model C' was abolished, however, the term continues to be used to describe government schools formerly reserved for white children.. These schools tend to produce better academic results than government schools formerly reserved for other race groups . Former 'Model C' schools are not private schools, as they are state-controlled. All schools in South Africa (including both independent schools and public schools) have the right to set compulsory school fees, and formerly model C schools tend to set much higher school fees than other public schools. Question: After apartheid, what types of schools are referred to as 'Model C' schools?
government schools formerly reserved for white children
