If your child is applying to a selective private school in Canada or the United States, chances are they will need to take either the ISEE or the SSAT. These two entrance exams are accepted by hundreds of independent schools, including well-known institutions like Upper Canada College, Havergal College, Branksome Hall, Phillips Exeter Academy, and Andover. For many families, the question is not simply “how do we prepare?” but “which test should we take?” Understanding the differences between the ISEE and SSAT can help you make a strategic decision that gives your child the best possible chance of admission.
What Is the Difference Between the ISEE and SSAT?
The ISEE (Independent School Entrance Exam) and the SSAT (Secondary School Admission Test) are the two most widely accepted private school entrance exams in North America. Both assess verbal reasoning, quantitative ability, reading comprehension, and writing, but they differ in structure, scoring method, and overall difficulty level.
The ISEE is administered by the Educational Records Bureau (ERB). It is offered at four levels: Primary (grades 2-4), Lower (grades 5-6), Middle (grades 7-8), and Upper (grades 9-11). The SSAT is managed by the Secondary School Admission Test Board and is offered at three levels: Elementary (grades 3-4), Middle (grades 5-7), and Upper (grades 8-11).
While many top private schools accept both exams, some have a clear preference. Researching your target schools before registering is an essential first step.
How Are the ISEE and SSAT Structured?
The format of the two exams is similar at a high level but differs in important ways that directly affect how your child should prepare.
| Feature | ISEE (Upper Level) | SSAT (Upper Level) |
|---|---|---|
| Total Testing Time | Approximately 2 hours 50 minutes | Approximately 3 hours 5 minutes |
| Sections | Verbal Reasoning, Quantitative Reasoning, Reading Comprehension, Math Achievement, Essay | Writing Sample, Quantitative (x2), Reading, Verbal |
| Analogies | No analogies tested | Yes, analogies are a key verbal component |
| Math Content | Arithmetic through pre-calculus | Arithmetic through geometry and algebra |
| Guessing Penalty | No penalty for wrong answers | 1/4 point deducted per wrong answer |
| Score Scale | 760-940 per section; stanine 1-9 | 500-800 per section; percentile rank |
One of the most significant structural differences is the guessing penalty on the SSAT. Because students lose a quarter point for each incorrect answer, strategic pacing and question selection matter more on the SSAT. On the ISEE, incorrect answers carry no penalty, which changes how students should approach uncertain questions.
How Is Each Exam Scored?
The ISEE and SSAT use different scoring systems, and understanding these differences helps set realistic expectations for your child’s preparation.
On the ISEE Upper Level, students receive a scaled score between 760 and 940 for each of the four scored sections. Their performance is then compared to other students who took the same level over the past three years, producing a stanine score from 1 to 9. Most competitive private schools look for stanine scores of 7 or above, which places a student in the top 23% of test-takers. Highly selective schools may expect stanine scores of 8 or 9.
The SSAT Upper Level uses a scaled score range of 500 to 800 per section, for a combined total between 1500 and 2400. Scores are presented as percentiles compared to other students in the same grade who have taken the exam over the past three years. Based on our experience working with students applying to top private schools, most selective programs expect SSAT scores above the 75th percentile, while schools like Phillips Exeter or Andover typically see successful applicants at the 90th percentile or higher.
Because both exams compare students against a highly motivated, self-selecting pool of applicants, strong scores require deliberate preparation rather than simply performing well in school.
Which Schools Accept the ISEE vs the SSAT?
Most top private schools in Canada and the United States accept both the ISEE and SSAT. However, some schools have preferences worth knowing about before you register.
- Schools that accept both: The majority of well-known boarding schools and day schools accept either exam. These include Choate Rosemary Hall, Hotchkiss, Upper Canada College, Havergal College, and Crescent School.
- Schools closely affiliated with the ERB (ISEE): Many urban independent day schools, particularly in Toronto, New York, and Boston, are ERB member schools and may recommend or prefer the ISEE.
- Schools that lean toward the SSAT: Several New England boarding schools have historically favored the SSAT. Always confirm with each school’s admissions office directly.
The safest approach is to check the admissions requirements page for every school on your child’s list before committing to a single exam.
Which Exam Should Your Child Take?
The right exam depends on your child’s academic strengths, the schools they are targeting, and how much time is available for preparation. According to experienced private school admissions tutors, taking a full-length timed practice test for each exam is the most reliable way to determine which test suits your child better.
Consider the ISEE if your child:
- Is strong in math through advanced algebra or pre-calculus
- Prefers a test with no guessing penalty
- Is applying to ERB member schools or Canadian independent schools
- Has a tighter preparation timeline and needs a more straightforward test structure
Consider the SSAT if your child:
- Is strong in verbal reasoning and comfortable with analogy-style questions
- Can apply strategic test-taking skills, including when to skip or guess
- Is primarily targeting New England boarding schools
- Has more preparation time available and responds well to strategy coaching
How Should Your Child Prepare for the ISEE or SSAT?
Families who begin ISEE or SSAT preparation 3 to 6 months in advance consistently achieve stronger scores than those who start in the final weeks before the exam. Both tests reward systematic, consistent practice over time.
Effective preparation includes:
- Diagnostic testing: Take a full-length practice test under timed conditions to establish a baseline score and identify weak areas in math, vocabulary, or reading.
- Targeted skill-building: Address vocabulary gaps and math concept weaknesses before shifting to full test simulations.
- Consistent practice sessions: Working on exam skills three to five days per week in focused 30-45 minute blocks is more effective than occasional long sessions.
- Vocabulary development: Both exams test sophisticated vocabulary. Students preparing for the SSAT should also study common analogy patterns and word relationships.
- Timed section practice: Pacing is critical on both exams. Regular timed practice builds the speed and composure needed on test day.
Working with a tutor who specializes in private school entrance exam preparation can significantly accelerate this process.

Frequently Asked Questions About ISEE vs SSAT
Can my child take both the ISEE and SSAT?
Yes. Many families register for both exams and submit the higher score to schools that accept either. This strategy works well if your child has adequate preparation time and wants to maximize their admissions options.
How many times can a student take the ISEE or SSAT?
Students may take the ISEE once per testing season (fall, winter, spring, summer), for a maximum of three times per year. The SSAT can be taken up to five times per year, and students choose which scores to send. Either way, thorough preparation before the first attempt is the most effective strategy.
What is a good ISEE score for private school admissions?
A good ISEE score depends on the school. Most competitive private schools look for stanine scores of 7 or above on each section, placing a student in the top 23% of test-takers. Highly selective schools typically expect stanine scores of 8 or 9.
What is a good SSAT score for private school admissions?
For most competitive private schools, an SSAT score above the 75th percentile is a strong result. For highly selective boarding schools, scores at the 90th percentile or above are often expected. A combined scaled score of 2100 or higher on the Upper Level is generally competitive at top programs.
When should my child start preparing for the ISEE or SSAT?
Most private school admissions experts recommend starting preparation at least 3 to 6 months before your target exam date. Students who begin earlier have more time to build vocabulary, strengthen math foundations, and develop test-taking strategy without the pressure of an imminent deadline.
