ISEE FAQ: Answers on the Test, Registration, Scores and Prep

The test

This section covers what the ISEE is, who runs it, how hard it is and how it is structured.

What is the ISEE?

The Independent School Entrance Exam (ISEE) is a standardized admission test used by independent schools for applicants to grades 2 through 12. It is administered by the nonprofit E3n (formerly ERB), and E3n reports that more than 1,200 independent schools around the world accept the results. Each school sets its own requirements, so the test is one part of an application alongside grades, recommendations and interviews.

Who administers the ISEE?

E3n (formerly ERB), at admission.org. E3n was formed in March 2026 when ERB, the former ISEE organization, merged with the Enrollment Management Association, which ran the SSAT. The two tests remain separate. Older articles and school pages that still cite ERB and erblearn.org describe the previous organization, although the old web address now redirects to the new site. Any new information on dates, fees or policies should be read from admission.org.

Is the ISEE hard?

Difficulty depends on the level, the student’s reading and vocabulary, and how comfortably the student works against the clock. Many students find the time limits and the Verbal Reasoning vocabulary more demanding than the math. Scores compare each student with other applicants to the same entry grade, so a hard question is not a sign of a weak result. The test is demanding but predictable, and a student who knows the format is usually less affected by timing.

How long is the ISEE?

The four scored sections take 110 minutes at the Lower Level and 130 minutes at the Middle and Upper Levels. A separate 30-minute essay follows and is not scored. Primary Level tests are shorter and have no essay. Check-in, instructions and breaks add to the time on the day, so families should plan for a morning or an afternoon rather than only the testing minutes.

Level	Verbal Reasoning	Quantitative Reasoning	Reading Comprehension	Mathematics Achievement	Scored total
Lower	34 questions, 20 min	38 questions, 35 min	25 questions, 25 min	30 questions, 30 min	127 questions, 110 min
Middle and Upper	40 questions, 20 min	37 questions, 35 min	36 questions, 35 min	47 questions, 40 min	160 questions, 130 min

How many questions are on the ISEE, and what subjects does it cover?

The Lower Level has 127 scored questions and the Middle and Upper Levels have 160, divided among Verbal Reasoning, Quantitative Reasoning, Reading Comprehension and Mathematics Achievement. One essay prompt follows at those three levels. Primary 3 and Primary 4 cover reading and mathematics only, and Primary 2 adds Auditory Comprehension. Question counts for the Primary Levels are given on the level pages.

Which ISEE level should a student take?

The level follows the grade the student is applying to enter, not the grade currently attended. Applicants to grades 2, 3 and 4 take Primary 2, 3 or 4. Applicants to grades 5–6 take the Lower Level, grades 7–8 the Middle Level, and grades 9–12 the Upper Level. A student applying from grade 7 to grade 8 therefore takes the Middle Level. The levels overview lists all six entry points.

Is there a penalty for guessing on the ISEE?

No. E3n states that students are scored only on correct answers, so there is no advantage to leaving a question blank. Students should answer every question, including those they cannot solve, and use any remaining time on questions they marked to revisit. This differs from the SSAT, which deducts a quarter point for each wrong answer at the Middle and Upper Levels.

Registration and logistics

This section covers where to register, which formats exist, what they cost and what happens if plans change.

Where do families register for the ISEE?

Families create a parent account on the E3n website, admission.org, and register the student there. The account is also where available test dates, score reports and school recipients are managed. The former erblearn.org address now redirects to admission.org. The registration guide compares the four test formats and sets out the steps in order. Creating the account is the first step, and one parent account can hold registrations for the student across all three testing seasons.

Can the ISEE be taken at home?

Yes. At-Home testing is one of four test formats, alongside school sites, E3n offices and Prometric test centers. It is a computer-based test with remote proctoring, so the student needs a suitable device, a stable connection and a quiet, approved testing space. Fees depend on whether a school or E3n organizes the session: $130 or $170 when a school organizes it, and $185 or $250 when E3n does, by grade band.

How much does the ISEE cost?

Fees depend on the format and on the grade the student is applying to enter. The table shows the main options, with the lower figure for applicants to grades 2–4 and the higher for grades 5–12. Late and on-site registrations at school sites cost more than regular registration. The fees guide gives the full schedule, including the differences between group and single-student sessions at E3n offices. Fees are reviewed each term, so the amount shown at checkout in the parent account is the amount that applies.

Format	Applicants to grades 2–4	Applicants to grades 5–12
At-Home (school-organized)	$130	$170
At-Home (E3n-organized)	$185	$250
At-School, regular registration	$130	$170
In-Office, group	$185	$225
Prometric test center	Not offered	$250

When are ISEE test dates, and how often can a student test?

A student may test once per testing season, up to three times in a school year. The seasons are commonly described as fall (August–November), winter (December–March) and spring/summer (April–July), although the months are not listed one by one on admission.org. Available dates are shown in the parent account at registration, and those dates take precedence. The test dates guide explains how to work backward from an application deadline.

Can an ISEE registration be rescheduled or canceled?

Yes, before the test day. A change at standard sites costs $50 when made at least one day before the test. Canceling costs $55, with the remaining balance refunded when the cancellation falls within 90 days of registration and no refund after that. A change is not possible on or after the test day. Prometric centers use a sliding scale that runs from free at 31 or more days before the test to $75 at 4 to 1 days, with no refund inside 4 days.

Is financial help available for ISEE fees?

Yes. E3n offers fee waivers for families with financial need. The request goes through the school the student is applying to, not directly to E3n, so the first step is to contact that school’s admission office and ask how it handles waivers. Families should do this before registering. The school can explain its own process and the documents it may ask for.

What should a student bring on test day?

The registration confirmation lists the requirements for the chosen format, and families should follow it exactly. Requirements typically cover the confirmation itself and acceptable identification, with separate rules for pencils and paper at a paper test and for devices and the room at a computer-based test. Rules differ by site and format, so reading the confirmation a few days ahead avoids problems. See the test day guide for a format-by-format checklist.

Scores and reports

This section explains what a score report contains, how to read it and how scores reach schools.

What is a good ISEE score?

No score determines admission by itself, and ISEEPrep lists no cut-off scores. Schools read the percentile and stanine for each section alongside grades, recommendations, interviews and the essay. A stanine of 4 to 6 falls in the middle of the distribution, and 7 to 9 in the upper range. Which results suit a particular school is a question for that school’s admission office.

Does the ISEE have a total score?

No. Each of the four scored sections receives its own scaled score, percentile and stanine, and the report does not combine them into a total or an average. Scaled scores run from 760 to 940 per section. Admission staff read the sections side by side, which is why a strong math result does not hide a weak verbal result. The scores guide explains each number.

What is a stanine?

A stanine is a nine-point scale that groups percentiles into bands, and it is the figure admission staff tend to read first. Stanines 4, 5 and 6 cover the middle 54 percentile points, while stanines 1–3 and 7–9 each cover 23 points at the bottom and top of the range. The table shows the bands. A single stanine therefore describes a range of percentiles, and two students in the same stanine can differ slightly in percentile. Reading both numbers together gives the clearest picture of where a student stands.

Stanine	Percentile range	Band
1–3	1–22	Lower
4	23–39	Middle
5	40–59	Middle
6	60–76	Middle
7–9	77–99	Upper

Who is the percentile compared with?

Percentiles compare a student with other students in the same entry grade who took the same level. A percentile of 80 means the student scored equal to or higher than 80 percent of that group. It does not compare the student with the whole school population, so a percentile may look lower than a class rank, which is normal for a test taken by a self-selected group of applicants.

Is the ISEE essay scored?

No. The essay is not part of any score. Families do not see the essay on the score report, but the schools the family chooses to send scores to receive a copy, and admission readers do read it. The essay is a 30-minute response to a single prompt at the Lower, Middle and Upper Levels, typed at computer-based sites and handwritten at paper sites.

How soon are ISEE scores released?

Computer-based tests are reported in 3 to 5 days and paper tests in 5 to 10 days. Once scores are posted, the family can add schools as recipients from the parent account, and adding schools does not carry an extra fee. The retakes and score sending guide covers when to retest and how recipients are chosen. Scores usually arrive well before most school deadlines, but families should confirm the date each school sets for receiving results.

How are ISEE scores sent to schools?

Families add each school to the parent account after scores are available, and E3n delivers the report along with the essay. Sending to additional schools costs nothing extra. Families should check each school’s deadline for receiving scores, because a school can set its own date.

Preparation

This section covers how long preparation takes, which materials exist and how to spend practice time.

How long should preparation for the ISEE take?

Working ranges used by the ISEEPrep teaching team are 2 to 4 months for the Primary Levels, 4 to 6 months for the Lower Level, 5 to 6 months for the Middle Level and 6 to 9 months for the Upper Level. These are experience-based estimates, not figures from E3n, and the right length depends on the student’s starting point. Vocabulary is the one area that cannot be compressed, so longer lead time helps at higher levels.

Are past ISEE tests available for practice?

E3n does not release past tests. It does offer practice materials, which are the closest match to the real format. Materials sold elsewhere as real or actual tests are usually recalled or imitated items of uneven quality. The practice items on this site are original and written by the ISEEPrep teaching team, and they are not questions from the actual ISEE and are not converted into ISEE scores.

How much vocabulary does the ISEE require?

E3n does not provide a word list. The demand rises with the level, and the Upper Level synonym questions approach academic reading vocabulary. A steady routine works better than cramming: learn words in groups by root and prefix, keep a fixed daily amount, and review them at spaced intervals through the whole preparation period. Reading widely in books and articles adds context that flashcards alone do not, and it helps with Reading Comprehension at the same time.

How often should a student take a full practice test?

During the middle of preparation, a timed full-length practice test every two to three weeks is a reasonable pace, moving to weekly near the test. After each one, sorting every miss into one of three groups helps: content not known, content known but answered wrongly, and questions not reached for lack of time. Each group points to a different fix: knowledge, accuracy or pacing.

A student is strong in math but weaker in English. Which should improve first?

Usually the weaker area. Schools read the four section results separately, and raising a section from stanine 4 to 6 typically matters more than raising a strong section from 8 to 9. Verbal Reasoning and Reading Comprehension also take longer to improve than math, so starting them early is sensible. A study plan for a given level can be arranged through a free consultation.

ISEE vs. SSAT

This section covers how the two tests differ and how to decide between them.

What is the difference between the ISEE and the SSAT?

Three differences matter most. The ISEE has no penalty for wrong answers, while the SSAT deducts a quarter point at the Middle and Upper Levels. The ISEE sets the level by the grade a student is applying to enter, while the SSAT sets it by the grade currently attended: Elementary for grades 3–4, Middle for grades 5–7 and Upper for grades 8–11. The ISEE allows one attempt per season, while the SSAT allows several per testing year. The ISEE vs. SSAT guide compares them in full.

Do schools accept both the ISEE and the SSAT?

Many independent schools accept either test, but some name only one. The reliable method is to check the admission page of each school on the list or to ask the admission office. When every school accepts both, one test is enough, and the student can choose the format that suits better. Students applying to schools that accept only one of the two tests have no choice to make, so the school list should be settled before preparation begins.

Can a student take both the ISEE and the SSAT?

Yes. Nothing in either test’s rules prevents it. In practice, preparing for both divides study time, since the question types and strategies differ. A common approach is to try a short timed set from each, compare how the student handles them, and then commit to one test, unless a school on the list accepts only the other. Two test dates close together also leave little time for review, so spacing them apart is advisable.

Are the ISEE and the SSAT now run by the same organization?

Yes. In March 2026, ERB and the Enrollment Management Association merged to form E3n, which now administers both tests. The ISEE and the SSAT remain separate tests with their own content, scoring and registration, and the merger did not change which tests individual schools accept. Families should keep checking each school’s current policy.

When the answer is not here

Questions about a specific school, the right level or a preparation schedule depend on the student’s grade and current skills. Families can book a free consultation to discuss these. Nothing on this page is a promise of a particular score or an admission outcome.
