It doesn’t surprise me that all freshman students were enrolled in AP classes (not necessarily seminar though). I have a friend that teaches in a struggling school in a neighboring district and they have made the move to require all students to take APUSH and other AP courses as a major state evaluation criteria is the percentage of students taking AP courses. The school can increase their metrics by having 100% participation even though passing rates, AP test scores, etc. will be dismal. Just another way to game the system for the district to keep the funding flowing but a disservice to the kids.
