Actually in Fremont, there is one school district with 5 high schools. The city is carved out into districts and generally based on proximity of home address, students assigned to the appropriate high school. The thing though is there is a huge ranking difference between the high schools. The top one is maybe in the 99% percentile in the state while the lower one is maybe 60% percentile. This makes for a huge pricing difference between houses maybe a few blocks apart to the degree of a 2x price difference. So the ones in the expensive houses will pay more property taxes but I believe the funding is equally divided among the high schools based on student population. In the end, probably the big difference is racial difference among different parts of the city and the affluence and education background of the parents that drive the difference in the school rankings.
