okay, the information you have been waiting for:
First of all, I would like to recommend that you check out the websites of any seminary you are looking into. You can find out a lot that way, I think. In particular, it is a good way to find out how the girls dress (not the dress code itself – but how they actually dress), since they have pictures of the girls.
You can also find out if the school in tzioni (on B’aer Miriam’s website, there are a lot of pictures of the Israeli flag, on Tomer Devora’s website, they talk about Yom HaAtzmaut options, for example).
Regarding B’aer Miriam:
1. It is very small. As of a few years ago, they generally had app. 30-50 girls a year.
2. They have a really good, warm staff who really care about the girls.
3. Very out-of-town school.
4. The school is tzioni. The administration is tzioni.
5. The teachers are a mix of Chareidi and Dati-Leumi.
6. The focus is on teaching Yiras Shamayim, not “hashkafic politics”.
7. They set girls up for Shabbos. I think all schools do, btw.
8. dress code = cover knees, sleeves to the elbow, not too low-cut
9. girls are a range of Frumkeit.
btw, this info is from app. 3 yrs ago, but it doesn’t sound like most of these facts would have changed. The one thing that can change in a seminary from year to year is the type of girls who go, so it might be kidai to get more recent info on that if possible.
