I don’t know. Like I said, I have had no involvement with the school for many years, and even then, my involvement was limited. These things can change a lot over the years.
At the time, most were baalei teshuvas, so they didn’t necessarily fit into the same categories as FFB’s do exactly. I think that most of them were still at a stage where they were growing religiously and they weren’t ready to pigeonhole themselves into a label yet. The school itself does not pressure the students to fit into a specific category. I always thought of the school as being closer to Yeshivish than to MO. My impression was that the students were a bit of a mix, but also closer to Yeshivish than to MO, but again, I can’t tell you for sure. From what I know of it, it seems to me that it would be a good match for you hashkafically.
My main concern for you would be the age level.
