Magnet schools usually require the student to provide their own transportation or the transportation might take a good deal of time.
My daughter went to a magnet program, but it was in the school for which we were zoned. Half the school was the ‘traditional’ program, and was heavily Hispanic (although not ESL, so even some neighborhood kids had to be bused to another middle school). The other half, the magnet, was not racially diverse at all - almost all white with some Asian students. If you looked at the school as a whole, it appeared to be diverse but the reality was the Hispanic kids were in the regular program and the white kids were in the IB program. Physically in different parts of the school and they didn’t melt in a big pot, but stayed very separate, very unequal. Very few traditional program kids were involved in band, orchestra, sports, drama, art. The were hardly involved in academics. On awards night, 95% of the awards went to magnet kids. It really was two separate schools but statistics were reported as one school.
