How does a school keep its high rating? Easy. Designate every senior English class as an AP class.
The school looks good because of all the students taking college level classes. It costs the school nothing because all students must take English anyway. The administration does not care how the grades come out as the school is judged only by the number enrolled, not the number passing the advanced placement exam.
Struggling students are not being prepared for what they will need in college. Parents are being bamboozled and the ones that belong are getting a watered down education.
