I hope your a person who has a lot of patience. As this is not as simple as alot of people think. Requires you to still do 6+ hours of work with your child and if your in a decent to good school district you have to turn in your reports weekly and all the major tests are held in private at a district school or office.
If you have the time and knowledge this is a great way to educate your child. Down fall they will lose there ability to interact with people in there own age group and tend to be more able to interact with adults. This can have bad out come also with a child acting to mature around the wrong people.
I know your urge to protect your daughter however these things happen every place not just school. Its better in my opinion to keep open channels of communications and always make time for your kid when you two can sit down and maybe do homework together and talk about school, kids or other. Don't get made at the small things as this can make the child not want to talk keep an open in these talks no matter what they are about.
Enough of my ramblings, Be sure to weigh the bad against the good when making a decision like this.
