How many schools to apply to for class of 2024.

We are expanding the list with “backfill” schools to cover prescreen schools. After prescreens we would like to be around 12. He is looking at a wide range of schools in the top 25 and others. In Louisiana, so limited local schools and he would prefer to go away from home. His list is BW, CCM, TXST, U of Arizona, Otterbein, Ball State, Rider, MSM, Point Park, Marymount Manhattan, Montclair St., Pace, Molloy/Cap21, Pace, Hartt, Webster. Also considering Wright St, Wagner, U of Arts. Any other suggestions?.
