<p>bookcases,
You're welcome, glad to pass on the information on to others who can use it. The Texas Tech, NIH and I think Cornell programs are open to students finishing their sophomore year (as well as junior year), so your son might be able to attend some next summer. The only thing that may hold him up is his age since he's young for his grade. My daughter is the same age as her cohorts, but was born in June and this sometimes was a problem as she missed the age cutoffs by a few days. Here's one I forgot, the Jackson Laboratory in Maine. Beaware that it includes a wide range of ages, including college students, so it is likely best for very mature and independent kids:
