When I arrived at G-Town our students were taking AP courses and the tests, but not performing all that well. I had one of our teachers tell me as a parent that my kid wouldn't pass the AP test, that no one really does. This left me asking a lot of questions when I subsequently entered as the principal.
After a lot of conversation, we've moved toward offering community college courses, taught by our teachers with the college curriculum. The credits earned are much more of a sure thing for our students, we've increased our enrollment substantially, and it's a wash financially which means our students earn college credit free of charge.
The only down side is that there are two departments where my teachers don't qualify (based on their graduate level work) to teach at the college level. I'm sure that won't be an issue at SLA. Best of luck on this issue.
