what makes TAG a BY school is their hashkafa. they follow the torah in respect to tznius, middos, and they follow the guide of rabbanim…theyr uniform is refined and tznius too.. and btw i dont think all the hebrew teachers are rabbi/rebbetzin.. def not rebbetzin..
also in my high school, ttly BY, i dont think a single teacher is rebbetzin title.. bt the few men teachers r all def rabbi..
