Why is it a lousy church school.  You just can't think outside of the box that is labeled Pete's Ideas of How Things Ought to be, Regardless of Reality.  In your mind, the only motive for a church school is to indoctrinate.  It couldn't possibly be to educate.  However, if they have regular assemblies, which ALL schools do, and if at the assemblies a devotion is given, that does not mean that the main purpose of the school is to indoctrinate.  And letting students have a quiet time of Bible reading, meditation and prayer is not indoctrination, it is healthy because today's kids are too hyper.  Now, you would have a case if during each class, the teacher did a devotion and spent time explaining the passage before opening a book or doing an experiment or having students practice cursive. I taught at two Christian schools and 95% of a typical week looked like the school I attended on the west side of Denver in the 50's 60's with 5% left for chapel once a week and devotions daily.
