You may have unrealistic expectations of what a normal public school should do. The average ACT score is 21. If your school has an average of 24, they are probably doing something right. On average, 70% of graduating HS seniors enroll in college in the fall. If your school sends 90%, then it is above average in sending students to college. As to what to do, have you considered moving to a better school district, even if it means looking for a different job?
