ISEE vs SSAT 2025: Which Test Is Right for Your Child?

The ISEE (Independent School Entrance Exam) and SSAT (Secondary School Admission Test) are the two most widely used standardized tests for independent school admissions. Most families applying to private schools in the US will encounter one or both of them. While they cover similar academic territory — verbal skills, quantitative reasoning, and reading comprehension — the two tests differ in important structural ways that can affect your child's performance and your prep strategy.

Side-by-Side Overview

Format and Structure Differences

The most meaningful structural difference between the two tests is in the verbal section.

The ISEE Verbal Reasoning section tests two question types: synonyms (identify the word most similar in meaning to the given word) and sentence completions (choose the best word or phrase to fill a blank in a sentence). Both formats reward deep vocabulary knowledge and contextual reasoning.

The SSAT Verbal section tests synonyms and analogies. Analogies are a completely different skill: they require the test-taker to identify the logical relationship between a pair of words and then find a second pair with the same relationship. For example: PAINTER : CANVAS :: SCULPTOR : ___ (answer: MARBLE). Students who have practiced analogy reasoning may have a meaningful advantage on the SSAT verbal section that doesn't translate to the ISEE.

The math sections are comparable in content at the same level, though the ISEE breaks math into two distinct sections (Quantitative Reasoning and Mathematics Achievement) while the SSAT has two Quantitative sections that are more similar to each other.

The Guessing Penalty: A Fundamental Difference

This is the most tactically important difference between the two tests.

This difference has practical implications for prep and test-day strategy. Students who tend to feel strongly about every answer and like to complete every question often do better on the ISEE. Students who are deliberate, selective, and comfortable skipping questions may adapt more naturally to the SSAT.

Verbal Section: Synonyms vs. Analogies

The SSAT's analogy questions are a distinct skill that requires explicit practice. Analogies test the ability to identify relationships — part-to-whole, cause-and-effect, degree, function, type, sequence, and more. A student who is a strong reader with a good vocabulary may nonetheless struggle with analogies on their first exposure, because the question format is unfamiliar.

The ISEE's sentence completions, by contrast, reward contextual vocabulary and reading skill. A student who reads widely and has broad vocabulary will often do well on ISEE sentence completions without specific analogy practice.

This is one of the most practical reasons to take a diagnostic test for both: some students find SSAT analogies intuitive; others find them frustrating. That preference often predicts performance.

Which Schools Prefer Which Test?

Most independent schools accept both tests. However, there are geographic and historical patterns:

• Northeast boarding schools (Exeter, Andover, Choate, Deerfield, Loomis, Hotchkiss, etc.): Historically associated with the SSAT. Many still list the SSAT prominently on admissions pages, though they also accept the ISEE.
• NYC independent day schools (Dalton, Horace Mann, Fieldston, Spence, Collegiate, etc.): Strong ISEE tradition through ERB. Many NYC schools explicitly list or prefer the ISEE.
• Bay Area independent schools: Lean ISEE for many schools, though the market is somewhat mixed.
• Southeast and Midwest schools: More variable — many accept both equally, and some lean SSAT.

Always verify with each specific school — testing preferences change over time, and some schools now list a preference they didn't have five years ago. A quick email to the admissions office asking "Do you have a preference between ISEE and SSAT?" is always worthwhile.

Score Choice: Neither Test Has It

A common misconception is that one test allows students to choose which scores to send. Neither test offers true score choice:

• ISEE: All scores from the current testing year and the prior testing year are sent to schools. Students may take the ISEE up to three times per year (once per season), and all results are reported.
• SSAT: All scores from the prior year are visible to schools. Students may take the SSAT up to 8 times per year with relatively flexible scheduling, but each score is reported.

This matters strategically. On the ISEE, the maximum of three tests per year limits exposure. On the SSAT, the higher test frequency means students can test more often — but also means more scores accumulate on the report. Schools generally look at the highest score across sittings, but the full record is visible.

Can Your Child Take Both Tests?

Technically, yes. Some families take both tests and submit the better result. However, preparing for both simultaneously is demanding and generally not recommended unless:

• Different schools on the list require or strongly prefer different tests
• The student has extensive time for prep (e.g., prep starting more than 4 months before deadlines)
• A diagnostic showed roughly comparable performance on both, making it genuinely unclear which test is a better fit

For most families, the better strategy is to take a timed diagnostic for both tests early in the prep process, compare the results, pick one, and prepare deeply for that test. Splitting prep time across both often results in mediocre preparation for both.
