High Academic can mean a range of schools. For most of us that means a school that is very hard to get into and is ranked highly by US News, Princeton Review, etc.
For example, Tufts comes up here often. The admit rate is 14.6 - very low, though there are some that are lower. If you search their website or Google for the term "student profile", there is usually a page for any school that will show you, at the very least, mean SAT and ACT scores. It would be instructive to look up the numbers for some target schools.
At Tufts the mean ACT is 32-35. So if your kid is in that range and has good grades he's definitely a HA kid and a likely recruit if the coach wants him. He might even be able to get in without help. If he's more like 29-30, he might be okay, depending on the level of influence and leeway that the coach has with admissions. Below that, he probably needs to retest.
