Each club is different. Some are very intense/competitive, others more middle of the road and yet others have teams, but are very relaxed in their approach to competition. Some clubs have active parent booster organizations to help offset the cost of meets, leos, travel etc. and others have none---parents have to pay for just about everything.
Coming from a school program, your dd may find a club program a little different. You need to check out as many gyms as possible to find one that has the right philosophy for you and your dd. Some clubs do USAG only, some have USAG and USAIGC, some also have rec leagues(depends on the state), the Y has its own program and some gyms do AAU. Lots to look at and consider. Ask lots of questions and do as many "trial" practices as possible before committing to any specific gym.
