We basically support public prep schools. Our graduation rate is 99% and our college admission rate is 96%. We pay for our schools through property taxes and get very little, if any, support from the state/feds. It's unusual, I think, in the sense that our property values are high because of the quality of the schools we support. Our property taxes are high -- crazy high -- accordingly.
Our high school ranks fifth in the state in average ACT scores with over 75% of the kids getting 30 and above. The downside is that the place is a pressure cooker and the kids are pushed to excel on all levels. I think you'll find more of this kind of academic support in the suburbs and less support in the urban and rural areas.
Edit: I just checked the numbers for last year's graduating class.
ACT: 441 students tested
20.1 State Average
Student/Faculty Ratio: 11:1
Faculty: 152; 92% hold Masters Degrees and 5% hold PhD degrees
