I think it is an extremely high quality school -- too high quality. Their content and standards are innapropriate for the grade-levels and they use a one-size-fits-all approach aimed at only the top students. If a student does not meet their expectations, the only approach the school seems to employ is hold them back rather than intervene earlier when it might be of more benefit academically and less detrimental emotionally. It is more about protecting the school's rankings than doing what's best for students. And, before you assume my comments simply stem from having children that have not been successful, I have two children -- the older one has excelled there and the younger one has struggled. In both cases, I felt the content and standards were out of line with the grade-level of the students.
I agree with the others who emphasized the positive academic aspects of this school. We have had some fantastic teachers. However, the students can be mean to each other; it is a very wealthy school and verbal bullying is frequent for kids who don't quite 'fit in' (in spite of the principal's valiant effort to eliminate it). Also, parent involvement in the school is somewhat limited, so if you have been very hands-on in another district before coming here, you might be surprised. Great academically, but there is more to your student's quality of life than test scores.
