Villas del Mar teaches using the Beka home schooling program from the U.S. It is a Christian based home schooling program. The first class of the day is a Bible class but, other than that, I wouldn't say it is a "very religious" school. My kids went there for 3 years before we moved back to the U.S. They were ahead of the other kids in their U.S. public school when returned to the U.S.
