It might be worthwhile for certain parents. I played division 1 sports in college so I travelled to dozens of schools and got to know plenty.
The problem parents have with the college process is understanding where a child fits. The parents of every B+ student with a 75th percentile test score has an initial list of every top 25 university and every top 25 LAC until they realize the kid doesn’t have a snow ball’s chance in hell. This is where the process breaks down and things get weird.
A professional will be able to match without getting punched in the nose.
Many parents also don’t realize that every kid that applies to Boston College from the same high school will not get in. No clue about this point.
The other thing that many parents fear is the kid going to a school that their friends have never heard of. That is a huge issue. “Middlebury??? Where is that, I’ve never heard of it”. Just imagine the embarrassment. The one that gets under my skin is " Colgate, isn’t that a small school?"
So maybe a professional has value.
