You might want to check out Lonely Planet's guide to the GAP year. Penty of resources and good info in there about deferring.

NEACAC Past-President Brad MacGowan has put together a pretty comprehensive list of gap options for his students. You can check it out at http://nnhscareercenter.home.comcast.net/gap-year.html.

I expect the Global Quest address is there, but if not, it's www.gquest.org.

Center for International Studies is great http://www.studyabroad-cis.com/

Google Cornelius Bull and Holly Bull who run a company that helps with Gap Year plans and also Gail Reardon of Taking Off.

The book Cool Colleges for the Hyper-Intelligent, Self-Directed, Late Blooming and Just Plain Different recommends a website run by Bob Gilpin, www.timeoutassociates.com. Bob Gilpin is apparently a consultant who charges a fee to refer families to these programs, but it still might be worth checking out. This book also recommends the book Taking Time Off: Inspiring Stories of Students Who Enjoyed Successful Breaks from College and How You Can Plan Your Own by Colin Hall and Ron Lieber. I haven't read it yet, but it sounds interesting!
