Our school encourages every student to take 1 AP class and no it hasn’t diluted any of the courses and our pass rates (3 or higher) are incredibly high. Some courses have 100% pass rates. All of our honors and AP classes are open enrollment for anyone who chooses them (except the Calculus classes and physics C which have pre-reqs). Some of the honors classes aren’t too challenging but the APs stay on course. Our district also has a college like policy of no more than 10% of a grade can be homework and final exams are 20% of the final grade. They have an informal policy of no extra credit assignments but one test re-take for test grades lower than an 80.
