I think he meant that those aren't schools you have to have good grades to get into and you don't have to be accepted. In other words, if you pay you can go to college there regardless of your academic success or lack thereof. A superintendent would probably be expected to have high achievers for children who have a choice of top schools and academic scholarships. Instead they're just average which could be construed as lack of educational leadership in the home by someone who is now in charge of the education policies of the biggest school district in the state.
