Hi, Kathie,
We did this last year for one course with DD(now 8) that was a math course based on Anno's Mysterious Multiplying Jar. I think they generally did a good job but it was not a great fit for DD; the course description that I saw before signing up was brief and seemed to focus on math, but the full description and course focused more on writing *stories about* math, so it was not the math enrichment I had been hoping for. Also there was a lot of emphasis in breaking the kids into groups for joint projects (also not a strength of DD's). They were nice about it and we finished the week but I think one of the science courses might have been better for her. Also, while it seems to be a very strong program and kids do have to qualify, my impression is they use a broad definition of gifted and so there are a lot of wonderful kids who are probably all on the honor roll in the courses (and so a great opportunity for socializing) but it wasn't terribly academically advanced. However, we've only done it once and may try again in a year or two just for fun.

Good luck!
