I've got ya beat, Chris. I've actually responded twice, but I forgot that to actually post to this site, I have to temporarily turn off my firewall.
Anyway, I know a young man who just graduated from an IB program in June. He attended a middle years IB program and a high school one. I don't think they offer elementary here yet. It was a lot of projects, which was right up his alley. He seems to think that colleges love IB programs (although, you might not be thinking that far ahead), and he ended up with a full scholarship to a state school. He is gifted.
Another girl I know (but not as well) graduated from an IB program. She had so much college credit, she finished college in 3 years. She had a harder time because, while gifted, she is more math-oriented than verbal-oriented. She did not attend the middle years program.
