I'm not sure if folks outside of the school community have had an opportunity to see this, but it looks like a community member created a pretty solid report on advanced placement programs and Corbett. I'm not new to the district so I have some idea of the program, but I still learned a lot from reading this report. I see how this could really help any families who are new to the district and would like to understand the methodologies at the high school.
The report is a pdf that you download (it's pretty long), but you can access it here:
