Not Catholic, but PSR (parish school of religion) is youth religious education for kids who are Catholic, but for whatever reason don't go to Catholic School. Maybe a couple hours a week, if Google is leading me in the right direction.
I wouldn't anticipate that religious instruction would have a strong academic bent - that's not at all the point of it. Sounds like you and your DH don't share a religion, and the underlying issue is a disagreement about religion, rather than a disagreement about appropriate academics?
