to consider sending DC to a Catholic school although I'm an atheist?

but its exam results are streets ahead of any other school in the area! So good that I think I could let Jesus into my life in spite of not believing in Him...

Yabu. I was tempted with dd but don't want to set a bad example of decieving people to get what you want from life. Just dont think it's right really.

I wouldn't. Certainly my experience teaching in a secondary Catholic school taught me that a) kids still get pregnant, even more so because they're not taught anything about birth control b) being gay as a teenager is the worst thing. c) sex education is null and void, as it's generally glossed over by the RE teacher d) Christian Aid week lasts forever. e) It's all a huge big nonsense, so why would you expose your kid to it if you didn't have to?

For me, my problem really came when I was unable to answer any of my form groups questions about their bodies in PSHE, as the RE teacher had to stand in and answer any that might contravene Catholic teachings ( ie: taught you not to be mightily guilty about your body).

Nope, don't do it. Move instead.

OP, unless your child is happy in this school which is completely in the hands of God, because that's how the school see things, your dc won't be one of the ones getting the good results. what do results matter at this age anyway? The only testing is a school assessment SATS.
I can't believe that people would put results of a school before their child's happiness.
