MommyOfTwo-
A TV in the house is not a deal-breaker with Prospect.
If you are considering it (good move, IMHO) he are a couple of pieces of info:
-The girls wear uniforms which are tzniusdik by all standards. I don’t think a four-year-old would need a uniform yet.
-The parents are from across the spectrum, but I don’t know of any mothers who don’t cover their hair or do wear pants.
-The administration is excellent.
-The sooner you speak to them, the better. It can be tough to get into some schools, just because of the demand for available spaces.
-You can speak to the administration about questions and concerns, but of course put your best foot forward (dress-wise, etc.) Try to speak to other parents and (if you have contacts) administration members with questions that you would prefer not to bring up on an interview.
-If you end up sending your daughters there, it would be no surprise if you were pleased enough that you keep them there thru high school.
Once again, hatzlacha raba.
