Choosing a Test
HSPT vs ISEE vs SSAT: which test does your school use?
If your family is applying to private high schools, the entrance exam depends on the school — not on you. Catholic schools overwhelmingly use the HSPT; independent schools use the ISEE or SSAT. Families applying to both kinds of schools often face two different tests in the same season.
The one-minute answer
| Your school list | Likely test |
|---|---|
| Catholic high schools (most of the U.S.) | HSPT |
| Catholic high schools in NYC | TACHS |
| Independent / non-religious private schools | ISEE or SSAT (school’s choice) |
| Boarding schools | Usually SSAT |
Always confirm on each school’s admissions page — a school’s required test is one of the first things listed under “how to apply.”
How the three tests compare
| HSPT | ISEE | SSAT | |
|---|---|---|---|
| Used by | Catholic high schools | Independent schools | Independent & boarding schools |
| Length | ~300 questions, ~2.5 hrs | ~160 questions + essay, ~2.7 hrs | ~150 questions + essay, ~3 hrs |
| Pacing | Fastest — under 30 sec/question | Moderate | Moderate |
| Guessing penalty | None — answer everything | None — answer everything | Yes (−¼ point per wrong answer) |
| Essay | No (some schools add one) | Yes (unscored, sent to schools) | Yes (unscored, sent to schools) |
| Retakes | Generally one sitting | Up to 3 times/year (one per season) | Multiple dates allowed |
| When taken | Late Nov–Jan of 8th grade | Fall/winter of application year | Fall/winter of application year |
What makes the HSPT different
The HSPT is the speed test of the three. Five sections — Verbal Skills, Quantitative Skills, Reading, Mathematics, Language — and roughly 300 questions in 2.5 hours, with no penalty for guessing and usually one sitting that counts for both admissions and merit scholarships. Its Verbal and Quantitative sections lean on question types most 8th graders have never seen — analogies, number series, logic statements — which is why familiarity moves scores quickly.

What makes the ISEE and SSAT different
Both are published for independent school admissions, both include an unscored essay that schools read, and both allow more time per question than the HSPT — but with harder vocabulary and more multi-step math. Two differences matter most for strategy: the SSAT penalizes wrong answers (a quarter point each), so blind guessing hurts, while the ISEE and HSPT reward answering everything. And both the ISEE and SSAT allow retakes across the season, where most HSPT schools accept a single sitting.
Applying to schools with different tests
Common in big metros: one Catholic school and one independent school on the same list means HSPT and ISEE or SSAT in the same fall. Three practical notes:
- Prep the shared core once. Reading comprehension, vocabulary, and arithmetic-through-basic-algebra carry across all three tests.
- Practice each test’s unique formats separately. HSPT number series and logic items, ISEE quantitative comparisons, SSAT analogies — these don’t transfer between tests.
- Schedule the harder-to-retake test with more care. The HSPT is usually one sitting; treat its date as fixed and book the ISEE/SSAT around it.
Frequently asked questions
Which test does my school require — HSPT, ISEE, or SSAT?
Most Catholic high schools use the HSPT. Independent (non-religious private) schools usually require the ISEE or SSAT. New York City Catholic schools use the TACHS instead. Always confirm on each school’s admissions page — it is usually listed under "How to apply."
Can my child take more than one of these tests?
Yes, and many families applying to both Catholic and independent schools do. The tests are run by different organizations and have separate registrations and test dates.
Which test is hardest?
They are hard in different ways. The HSPT is a speed test — about 30 seconds per question. The ISEE and SSAT allow more time per question but include harder vocabulary and, on the SSAT, a guessing penalty. A student can score very differently across them.
Do HSPT prep and ISEE/SSAT prep overlap?
Partially. Reading comprehension, vocabulary, and core math overlap heavily. The HSPT’s analogies overlap with the SSAT’s. But each test has unique question types and pacing, so students should practice in the format of the test they will actually take.
