The philosophy Indiana is to have big schools...the schools surrounding Indianapolis for example have between 3-5000 kids. That is one football staff, one band director, one cafeteria manager, etc. From a facilities standpoint, it is one auditorium, one football stadium, etc.Not in my experience. Larger schools tend to spend more money per student. Part of that may be that larger schools are in urban areas, but more importantly I find that larger schools have more bloated bureaucracies.
Two smaller schools might have one principal each. If they merge, there tends to be one overall principal and then two-vice principals. Instead of one athletic director apiece, their is now one overall athletic director and two assistant AD's. Etc.
