A side note regarding Sumner Academy: It could be said that, athletically speaking, they are already at a bit of a disadvantage compared to most other schools in the state. As Contrarian mentioned, the students are required to maintain a minimum GPA (2.5 I think - I could be wrong), or they must attend another school. Behavioral issues are treated similarly. The resulting attrition rate between 8th and 12th grades is approximately 50%. The number of freshmen and sophomores who attend school there greatly exceeds the number of juniors and seniors, and the composition of their athletic teams reflects that. The upside is that Sumner Academy is a terrific college preparatory environment for kids who are disciplined and motivated. When you see one of their teams take the mat/court/field, you can be assured that you are looking at a high quality group of kids.

FYI: U.S. News and World Report has them listed as the 62nd best high school in the country this year.
