First, check the schools
Most independent schools in New York accept either exam, but not all do. Confirm with every school on your list before choosing — this takes an email and removes the question entirely.
The difference that should decide it
On the ISEE there is no penalty for a wrong answer. On the SSAT there is — a fraction of a mark is deducted for each incorrect response, though not for a blank.
That single rule changes how a student should behave. On the ISEE, every question gets an answer; a blank is strictly worse than a guess. On the SSAT, a genuinely random guess has a small negative expected value, and students are advised to skip when they can eliminate nothing.
For an anxious student who freezes over whether to answer, the ISEE removes the decision entirely. That is a real argument for choosing it.
Other differences
| ISEE | SSAT | |
|---|---|---|
| Wrong-answer penalty | None | Yes |
| Reported as | Stanines 1–9 | Scaled scores and percentiles |
| Vocabulary style | Synonyms, sentence completions | Synonyms, analogies |
| Math sections | Two, with different jobs | Two quantitative sections |
| Essay | Unscored, sent to schools | Unscored, sent to schools |
Question style
The SSAT leans on analogies, which are a distinct skill and a real obstacle for students who have never met them. The ISEE uses sentence completions instead, which sit closer to ordinary reading.
The ISEE's Quantitative Reasoning section, with its comparison questions, is the mirror-image obstacle: unfamiliar, and a problem until it is practiced.
How to choose in practice
Sit a practice section of each and see which one the student handles better. That is worth more than any comparison table, this one included.
We build ISEE practice exams at all three levels — start with which level your child takes, then ten free questions.
Practice the real thing
Our ISEE exams are full length and written from scratch — every wrong answer carries its own explanation, so a child learns what they got wrong and why. Ten questions are free, with no account and no card. After that it is five credits an exam.
