The Upper West Side picture
One list, two philosophies
The Upper West Side’s independent schools do not line up on a single axis the way the East Side’s do. Trinity, at 139 West 91st Street, is a K–12 college-preparatory school. Columbia Grammar & Preparatory, at 5 West 93rd Street, is co-ed and traditional. Calhoun, whose main building at 433 West End Avenue takes grades 5 through 12, is explicitly progressive. Collegiate, all-boys, left its home of 125 years on the West Side in 2018 for a purpose-built campus at 301 Freedom Place South.
So a West Side family often ends up with a genuinely mixed list: two schools that treat the ISEE as a serious data point, and one that treats it as one folder in a file that also holds a classroom visit, a writing sample and a teacher’s letter. Both are legitimate ways to read a score. They are not the same preparation problem.
There is a second wrinkle here that the East Side largely does not have: entry grades differ across the list. Calhoun’s main building begins at grade 5, which lines up with ISEE Lower Level entry; other schools on the same family’s list take their largest outside cohorts at different points. Ask each admissions office which grades it actually opens to outside applicants before you fix a testing season — it is the question that most often changes the timeline.

How we work here
Prepping for a list that reads the score two ways
The test is the same everywhere in New York. What changes from one neighborhood to the next is the shape of the school list — and the list is what the plan is built around.
We separate the score target from the application work
On a mixed list, raising a stanine from 6 to 8 is worth a great deal at one school and very little at another. We say which is which for your specific list, so the family spends its autumn on the thing that actually moves, instead of pushing a number that the school reading it has already told you is not the deciding factor.
Progressive schooling is not a reason to skip the test
Children coming out of progressive lower schools are often strong readers and thinkers who have simply never sat a timed multiple-choice exam. That is a format gap, not an ability gap, and it closes fast — but only if the prep treats it as pacing and test mechanics rather than as remediation.
Different entry grades mean different test levels
The ISEE splits into Lower, Middle and Upper Level by the grade your child is applying to, not by their age or current school. When one family’s list spans two entry points, that can mean two different test levels in play. We settle the level first, then build the plan; getting this backwards costs weeks.
Getting here
From Upper West Side to 928 Broadway
Our center is at 928 Broadway in the Flatiron District, between 21st and 22nd Street. From the Upper West Side the simplest route is the 1: it runs local down Seventh Avenue and stops at 23rd Street, a short walk east to Broadway. From 86th or 79th Street that is a single ride with no transfer.
Sessions run after school and on weekend mornings. Where the West Side week is already full — and on the UWS it usually is, between sports and the school’s own calendar — the identical program runs live online: same tutor, shared whiteboard, same full-length timed practice tests with section-by-section score reports.
- 1From 96th, 86th, 79th, 72nd or 66th Street. One seat to 23rd Street (Seventh Avenue), then a short walk east along 23rd to Broadway.
- 2 / 3From 96th or 72nd Street. Express to 14th Street, then the 1 back up one stop or a ten-minute walk.
- B / DFrom Central Park West stops (B runs weekdays only). Down Sixth Avenue to 23rd Street, then two blocks east to Broadway.
Before you book a sitting, check the ISEE test dates — the testing seasons, the one-sitting-per-season rule and the registration cut-offs. Session rates are on the pricing page.
Upper West Side FAQ
What Upper West Side parents ask us
Do progressive Upper West Side schools actually look at the ISEE?+
Schools differ, and the honest answer is that some weigh it heavily and some treat it as one item in a file that also contains a classroom visit, a writing sample and teacher letters. Ask each admissions office directly how it uses the score. We will then tell you where prep time is worth spending on your particular list rather than assuming it matters equally everywhere.
Which ISEE level does my child sit?+
The level follows the grade your child is applying to enter, not their current grade or age: Lower Level for entry into grades 5 and 6, Middle Level for 7 and 8, Upper Level for 9 and above. If your list spans two entry grades, confirm with each school which cohort it is admitting your child into before you register.
My child has never taken a timed multiple-choice test. Is that a problem?+
It is common on the West Side and it is a format problem rather than an ability problem. The first diagnostic usually shows a child who knows the material and is losing points to pacing and to answer-choice mechanics. Those close quickly with drilled practice under real timing — which is exactly what the practice-test cycle is for.
Can we do sessions online instead of coming down to Flatiron?+
Yes, and a good share of our West Side families do. The online program mirrors the in-person one: live one-on-one, a shared interactive whiteboard, and full-length timed practice tests scored section by section. Some families run in person in the autumn and online once the school calendar tightens.
What does it cost?+
Sessions are $125 each after a one-time $150 diagnostic, billed session by session with no package and no contract. Every figure is on our pricing page.
Some schools on your list may ask for a different admissions test instead — boarding schools in particular. If that is your situation, start on our SSAT prep page. For the whole admissions picture — timeline, feeder schools, borough trends — read the ISEE prep guide for NYC parents.
