In my limited experience, coaches at ID clinics will not project what level your son will play at in college when he’s a sophomore. Some camps have a form where they give feedback, with the division level, but will only circle the d1 or d3 for rising seniors. While irritating at the time, i now understand that this is because boys can change over the years, up or down, so they are probably right.
Again, ask the ODP coach, his club coach etc for their opinions – they know him best and have seen him play the most, right?
I’m pushing the above (but having made my point will stop now 
) because it is a really good starting point to figure out the level of soccer, which is a first step in narrowing down the hundreds of possible schools out there. It’s always a good idea to go to some camps and see what they are like, see the school, meet the coaches etc.
Good luck, and enjoy it! I love watching my son play, and seeing him at ID camps has been fun.
