This whole thing is stupid. Can someone explain why someone who is not so frum* want to send their kid to a school that is more frum then them?
And if you do want to do that, stretch a little. Go out of your comfort zone and start being a better person. Why should the school lower their standards for you? You should be the one to adapt to their standards.
* I’m not talking about not frum like eating chalav stam, I’m talking about hair covering not frum.
