If your child is applying to private school, you've almost certainly encountered two acronyms: ISEE and SSAT. Both are admissions tests. Both evaluate verbal reasoning, reading, and math. And both are accepted by many of the same schools. So which one should your child take?
The answer isn't always obvious — and getting it wrong can cost your child a competitive advantage. At Victory Prep Tutors, we've prepared students for both exams since 2014, and we've developed a clear framework for making this decision. If you've already decided on the ISEE, check out our level-specific guides: Lower Level, Middle Level, or Upper Level. Here's everything you need to know.
The Key Differences at a Glance
Before diving deep, here's the most important difference between the two tests: the ISEE has no guessing penalty; the SSAT deducts points for wrong answers. This single difference shapes the entire test-taking strategy for each exam.
The two tests are also administered by different organizations. The ISEE is administered by the ERB (Educational Records Bureau), while the SSAT is administered by the Enrollment Management Association (EMA). Each has its own registration process, testing calendar, and score reporting system.
Two more critical differences:
- Retake policy: The ISEE allows one test per testing season (Fall, Winter, Spring/Summer) — so most students get two attempts at most. The SSAT can be taken as many times as the student wants, with all recent scores reportable.
- Score reporting: ISEE sends scores to up to six schools; families choose which scores to send. SSAT's score reporting practices vary — check each school's requirements carefully.
Which Texas Private Schools Accept Which Test?
For families in the Dallas-Fort Worth area specifically, knowing which exam each school requires or prefers is the most practical starting point. Here's where the major Texas private schools stand:
Hockaday School accepts both the ISEE and the SSAT for all grade levels. Hockaday is one of the most competitive all-girls schools in the country, and their admissions team reviews scores from either exam without preference. Because of this flexibility, we generally recommend the exam that better suits your daughter's test-taking style.
St. Mark's School of Texas accepts both the ISEE and SSAT for admissions to grades 9–12. St. Mark's uses the ISEE Upper Level or SSAT Upper Level depending on the student's preference. Given that St. Mark's is a highly selective all-boys school, students applying should aim for stanine 7–9 scores or SSAT scores in the 80th percentile or above.
Episcopal School of Dallas accepts both the ISEE and the SSAT for admissions testing. ESD enrolls students from pre-K through 12th grade, and for Upper School applicants, they use either the ISEE Upper Level or SSAT Upper Level. Episcopal's admissions office evaluates both tests equally — the decision is yours.
Greenhill School requires admissions test scores for students applying to grades 6–12. Greenhill accepts both the ISEE and SSAT and does not express a formal preference between the two. For Upper School applicants, the relevant tests are the ISEE Upper Level or SSAT Upper Level.
Parish Episcopal School accepts both exams for its Middle and Upper School applicants. Parish has grown significantly in selectivity and now draws applicants from across the DFW area. For Upper School admissions, either the ISEE Upper Level or SSAT Upper Level is accepted.
Admissions test requirements can change year to year. Always confirm the current policy directly with each school's admissions office before registering for a test. This is especially true if your child is applying to multiple schools — some may have changed their accepted exams recently.
Format Comparison: Side by Side
The structure of the two tests differs meaningfully. Here's a side-by-side breakdown for the Upper Level versions (for students applying to grades 9–12):
| Feature | ISEE Upper Level | SSAT Upper Level |
|---|---|---|
| Administrator | ERB | EMA |
| Total Time | ~2 hrs 40 min | ~3 hrs 5 min |
| Sections | Verbal, QR, Reading, Math Achievement + Essay | Verbal, Quantitative, Reading + Writing Sample |
| Guessing Penalty | No penalty | –¼ point per wrong answer |
| Math Sections | 2 (QR + Math Achievement) | 1 (Quantitative) |
| Retakes Allowed | Once per testing season | Unlimited |
| Analogy Questions | No | Yes |
| Experimental Questions | Yes (unscored, unlabeled) | Yes (unscored, unlabeled) |
One notable structural difference: the ISEE has two math sections — Quantitative Reasoning (which emphasizes logical/comparative problem-solving) and Mathematics Achievement (which tests grade-level math content directly). The SSAT has a single Quantitative section. This means math-strong students may prefer the ISEE, where there are more opportunities to demonstrate quantitative ability.
The SSAT also includes analogy questions in its verbal section — a format that requires students to identify relationships between word pairs. The ISEE does not have analogies. Students who have never practiced analogies often find them disorienting on their first practice test. If your child is choosing the SSAT, analogy practice is non-negotiable.
How Scoring Works on Each Test
The scoring systems are quite different, and understanding them is essential for setting goals.
ISEE Scoring
The ISEE reports four key numbers for each section: a scaled score (760–940), a percentile rank (1–99), and a stanine (1–9). Schools primarily focus on the stanine and percentile. Because there's no guessing penalty, raw scores equal the number of correct answers — making the strategy simple: answer every question.
SSAT Scoring
The SSAT is scored on a scaled score range (500–800 per section, 1500–2400 total for Upper Level). Crucially, the scoring formula is: +1 for each correct answer, 0 for each omitted answer, and –¼ for each wrong answer. This guessing penalty fundamentally changes strategy. Students should only guess when they can eliminate at least one answer choice — pure random guessing is neutral in expectation, but impulsive guessing on hard questions actively hurts the score.
Students who use ISEE strategy on the SSAT — answering every question regardless — often hurt their scores. The SSAT requires a disciplined "skip vs. guess" decision on every uncertain question. This is a skill that takes practice to develop. If your child is taking the SSAT, understanding the penalty is step one.
Both tests norm scores against other students who took the same test — not the general student population. Like the ISEE, the SSAT comparison pool consists of academically motivated private school applicants. A 75th percentile on the SSAT reflects strong performance in a highly competitive group. Our ISEE prep overview explains how stanines and percentile ranks work in detail.
Which Test Is Easier?
This is the question we hear most often, and the honest answer is: it depends on the student.
"There's no objectively easier test between the ISEE and SSAT. The right test is the one that plays to your child's specific strengths — and the only way to know for sure is to take a practice test of each."
That said, some patterns emerge from our work with thousands of students:
- Strong math students often prefer the ISEE because there are two scored math sections, giving them more opportunities to demonstrate quantitative strength.
- Students who read quickly and are comfortable with analogies tend to score well on the SSAT's verbal section.
- Students who tend to be impulsive guessers are often better served by the ISEE — where there's no downside to guessing — than the SSAT.
- Students who want multiple test attempts benefit from the SSAT's unlimited retake policy, especially if the application timeline allows for it.
- Students applying only to schools that prefer the ISEE shouldn't spend time on the SSAT — always let the school list drive the decision.
How to Make the Decision
Here's the framework we use at VPT when a family is trying to decide:
Step 1: Check the school list. Before anything else, confirm which tests each of your target schools accepts. If all of your target schools accept both, move to Step 2. If any school requires one specific test, that test takes priority.
Step 2: Take one practice test of each. Don't guess which test your child will do better on — measure it. Sit your child down with a timed practice ISEE and a timed practice SSAT on separate days. Compare the percentile results and, just as importantly, how your child felt during each test.
Step 3: Assess the timeline. If your child has a tight timeline (less than 4 months before the application deadline), choose one test and focus entirely on it. Splitting prep time between two tests rarely produces strong results on either. If time allows, the diagnostic approach in Step 2 is worth taking.
Step 4: Consider retake flexibility. If your child is a student whose scores tend to improve significantly with practice, the SSAT's unlimited retake policy is a real advantage. If prep time is limited and your child tends to perform best under well-prepared, high-stakes conditions, the ISEE's single-attempt-per-season structure won't be a disadvantage.
Prep Strategies: What Changes Between the Two Tests
If your child has selected a test, here's how prep should differ between the two:
Preparing for the ISEE
- Master Quantitative Comparison (QC) strategy — this format is unique to the ISEE and unfamiliar to most students.
- Build vocabulary systematically over months, not weeks. Roots, prefixes, and suffixes are as important as individual words.
- Practice answering every question — never leave a blank, since there's no penalty.
- Focus on the essay as a writing sample, not just a time filler. Schools read it carefully.
- Remember: you likely have one or two shots. Treat every practice test seriously.
Preparing for the SSAT
- Practice analogies extensively. Many students find this the most unfamiliar section, and consistent practice yields rapid improvement.
- Develop a "skip vs. guess" decision rule — only guess when you can eliminate at least one answer choice.
- Because you can retake, use your first attempt as a high-stakes diagnostic to identify areas for improvement on subsequent sittings.
- Practice the writing sample (an essay prompt) — it's sent to schools even though it's not scored.
- Don't underestimate the verbal section. SSAT vocabulary is as demanding as the ISEE's.
In our experience with 11,000+ students, the most important factor isn't which test is "easier" — it's how prepared your child is for whichever test they take. A well-prepared ISEE student will dramatically outperform an unprepared SSAT student, and vice versa. Start early, take at least one full-length diagnostic, and build your prep plan from real data about your child's strengths and weaknesses.
