I see you are in the LA area. You could combine some good advice already given here. He could attend a college prospect camp to get a feel for camp/showcase atmosphere, focus on grades, skill improvement and integration into the HS program by being the best teammate he can be and then just swing by the PG Sunshine event as a spectator for free. It is a great event and getting an early look could be quite helpful in giving him perspective, if he is really interested in knowing at this point.
It is also a good idea (and a lot of fun for the boys who truly love the game) to just go watch some college games at different levels. You have plenty of choices near you.
If the player is a truly outstanding player as a freshman, see PG's response.
