Does anyone on here have a comparative perspective on how differently things like grammar and math are taught at these two schools in the elementary years? Is the traditional/progressive thing really a big difference or is it just sort of branding and they really teach things pretty similarly?

This would truly be the bottom of my list of concerns if I were trying to choose between these two schools. Both of them can effectively teach grammar and math.

Sounds like you go to a Dalton.

@Anonymous I have no opinion on this matter, but I love your response.

Brearley's HS math classes are limited. Girls must take same math as their grade, for instance, a 9th grader cannot take Algebra 2 and must take Geometry because the scheduling doesn't allow for flexibility. Brearley girls go to Dalton to take higher math after school.

I thought all of the TT schools try to provide at least higher level/multi variable calculus at the school if there is enough interest but if not they take it through inter school?

@Anonymous I don't recall seeing any of the TT schools offering muti-variable calculus; maybe through interschool.

To follow up on my own post, I figured if any TT school would offer multi-variable calculus it would be HM. But nope: Neither does HCHS: https://hunterschools.myschoolapp.com/ftpimages/602/download/download_1966659.pdf.

OP: This is all so interesting, thank you. I was originally asking about math and grammar instruction in the lower school, though. Does anyone have insight into that? Thanks.

In my experience, lower schools follow more similar curriculums. Some may do more math drills than others. All follow closely to common core math. Grammar is almost never explicity taught anymore. Just learn by writing.

9th graders take Geometry at Brearley? I took Geometry in 9th back in the 90s at my suburban HS. I would have expected more from Brearley!

Are you trying to come up with a First Choice ? My advice, love the one who loves you so you can be sure to get a placement.
