Thank you for all the feedback, I really appreciate it. Yes, I realize that she is only 7 but I would rather get her started in the right direction then keep switching disciplines. I'm obviously not looking for her to be defending herself right now, it's the skills she's developing now that will improve and assist her as she gets older.
I did consider Brazilian Jiu Jitsu, I'm just not convinced in a real world altercation that it's going to the ground. I always thought it was more advantageous to get upon on your feet as fast as possible. So I was leaning more towards standing disciplines. I think people are really on the grappling, etc band wagon because of MMA (IMO no offenses) but I've have yet to see UFC - Street Edition.
The ones I'm really interested in she will have to be older. So other options are Wing Chun, Aikido - they offer children's classes.
If those with experience feel TKD is a good base, I'll suck up the cost. I just want to make sure that after 5 years of doing forms she's not in an altercation (school bully, etc) and can only think of what form will work.
The prices seem not too bad.
The school I trained in charged onward of 55 a month, but the school was open 6 days a week (although the instructor did not want to see students more than three times), tests, every 2 month, 50 for color belts, 95 for BBs.
The school the old man ran (my instructor's instructor) was quiet a bit higher in cost over all. Same program, same schedule....
However, we had a minimum attendance for tests. Higher up in rank you had to participate more often in the two to four month ahead of time. Which I seem to see was a bit of a problem over the summer. Which is ok, you don't want the kid to burn out. Matter of fact I heard a parent complain about TKD being an ongoing thing, not seasonal like the rest of the kid's activities (but he also brouht his daughter in every single day, had her burned out by the time she reached her BB)
I am a bit concerned about the 'she'll pass' having sat in on many tests. Yes, most every kid did pass. Unless you really could not get your form together in three tries, you passed. Unless you could not break the board (red belt on up for us) you passed. A lot of kids got their next belt basically for not sucking too badly.
However, we had the policy, if you should unexpectedly not pass, the next test was on the house, until you did pass.
We actually got a couple of freebies when the kid did not break boards a couple of times. I found that to be the biggest learning experience, to tell you the truth!
As to what style, MMA is probably best: If you fight standing up, you are toast when you go to ground. Note: When, not if.
When you grapple, you get your head kicked in by a standing up fighter, until you get him/her down to your playing field.
Several years ago the organization instituted what they called at that time 'Minor Fields of Study', a series of classes supposedly supplementing TKD. One was Hanmudo, a mix of Hapkido and another traditional Korean art, including a lot of joint locks and work with pressure points and throws. Much fun, but rather painful after an evening of practice
the other was 'ground escapes' which then morphed into BJJ. The initial idea being that as TKDs our strength is on our feet, but poop happens and we need to be able to get quickly and fast back on our feet to our game. "It makes us better fighters" as my instructor put it back then.
I think the real self defense benefits girls get from Martial Arts is that they will be fit, self aware and confident. I have seen a few little girls come through the doors, having a bit of a hard time to do the things they otherwise do not get to do: Be loud and assertive, forceful even. There is not much most anybody can do when the bad guy is much larger, or carries a weapon.
But being self confident makes everybody much less of a target.
