We will do so next year (he has one more year before starting "real school").
But, I agree with others that you need to check on the school very thoroughly. Like any other private school, its up to you to do the research. Make sure what they are teaching gels with your beliefs, both in terms of religion and basic education. We are headed to a school that is big on values but not on "doctrine", which is why I like it so much. Because some Christian churches are so into heavy-handed discipline, that is an especially important area to do your homework on (remembering that the Ezzos and Pearls call themselves Christian). Because many of the laws governing public schools don't apply, you need to ask lots and lots of questions. I am so lucky because I worked around this school for six years, so feel very comfortable sending my kids there.
