One of the elders in my church has had 3 of his kids at the school, and he loves it. My son and my daughters have been going to summer camps, and so far it has all been wonderful. They pray before and at the end of each class. They are very kind to my daughter who has special needs. They don’t have a Gay/Lesbian clubs or “Day of Silence” like the Catholic schools do in our area.
My daughters go to a Christian school that uses secular books and Bible books, and it is a fantastic very genuine school. I think it is in the way the school handles the material.
My son used to go to a Christian school that solely relied on Christian books, and we ended up pulling him out of that school and putting him in public. At that school, Pokemon and Harry Potter were evil. They also did not treat kids with special needs well, and they pushed lots of parents to put their kids on Ritalin.
Be weary of the ruling and the State of CA, not your church school.
