Does someone come out to your house, with a clipboard, watch you do your thing, and go "yep, you're good. You have a secularity quotient of just 0.16 thinglefrongs! Keep right on making America great again!" or alternatively, "I'm sorry Mr Malraux, but you have an excessive amount of religiosity and bollocksism in your curriculum. You'll need to fill out this short 30-page self-assessment form, and submit to a bi-weekly surveillance visit until we are satisfied. Which will be never, obvs. Mine's white, two sugars. Prefer hob-nobs to digestives."

I mean, I get your point, but it's hard to separate religious nuts who simply keep their kids home to ensure their levels of bronze-age misogynistic fantasy are maintained, and those who actually give their sprogs a decent brain-training (i.e. you).
