My DD did TIC and she liked it, but I didn't like that it was ages 9-14 in a single group (she was the only 9yo) and she was the only girl in her group. Even all the counselors for her group were male.
It really didn't feel great that she was the only girl with 14 older boys + 2 college age male counselors. Her "build" partner for the week was 14 yo boy. That's a huge, huge maturity gap. They should have worked that out better and gender balanced somehow.
She was originally supposed to be in a younger group, but they overenrolled that group so they moved her up to adjust the group sizes.
