The ISEE (Independent School Entrance Exam) is the admissions test that more than 1,200 independent schools accept for students applying to grades 2 through 12. It is run by E3n, the nonprofit formed by ERB and EMA. Lower, Middle and Upper Level students take four multiple-choice sections and an unscored essay, and schools mostly read the 1-9 stanine for each section.

The ISEE is the Independent School Entrance Exam — a standardized admissions test used for entry into private, parochial, and independent schools for grades 2 through 12. It is the dominant admissions exam for independent day schools across the United States, and its scores travel directly from the test provider to every school a family designates.
The ISEE is developed and administered by E3n, a nonprofit educational assessment organization. ERB and EMA have merged into a single nonprofit, E3n, and the ISEE and SSAT continue under their own names. E3n builds the test, operates the registration portal, runs the testing logistics at partner schools and Prometric centers, and distributes score reports to the schools selected on each registration. Because it is a single administrator across thousands of testing sites, the ISEE offers more flexible testing options than any other K-12 admissions exam.
The ISEE is accepted by more than 1,200 independent schools worldwide as part of their admissions process. This makes it the default test for most private day schools in the Northeast, mid-Atlantic, and urban markets like New York, Boston, and Los Angeles. A growing number of international independent schools also accept ISEE scores for K-12 admissions.
ISEE scores are one input in a holistic admissions review — not a gatekeeper score that makes or breaks an application. Admissions committees also weigh transcripts, teacher recommendations, student and parent interviews, application essays, and in many cases an on-campus visit. A strong ISEE score helps, but an average score alongside a strong overall profile is regularly enough at competitive schools.
The ISEE has four levels, each targeted at a specific grade of entry. One of the most common parent mistakes is picking the wrong level, because the test level is chosen by the grade the student is applying to enter — not the student's current grade. A 6th grader applying for 7th grade entry takes the Middle Level, not the Lower Level.
The Primary Level serves students entering grades 2, 3, and 4, with separate sub-forms for each entry grade. Lower Level is for grades 5 and 6 entry. Middle Level is for grades 7 and 8 entry. Upper Level covers all secondary-school entry from grade 9 through grade 12 on a single form.
| Level | Grade Entering | Typical Current Grade |
|---|---|---|
| Primary 2 | Grade 2 | Grade 1 |
| Primary 3 | Grade 3 | Grade 2 |
| Primary 4 | Grade 4 | Grade 3 |
| Lower Level | Grades 5-6 | Grades 4-5 |
| Middle Level | Grades 7-8 | Grades 6-7 |
| Upper Level | Grades 9-12 | Grades 8-11 |
Double-check the level in your ISEE parent account (iseeonline.erblearn.org) before paying. A test taken at the wrong level won't give schools the scores they need, and rescheduling or retesting costs extra. If in doubt, match the level to the grade the student will enroll in the fall after the test — not the grade they are currently in.
The Primary levels are much shorter: two multiple-choice sections, Reading and Mathematics, in 53 to 60 minutes with one 10-minute break. The Primary 2 Reading section also includes a few Auditory Comprehension questions that are read aloud. In 2026-27 there is no writing sample at any Primary level.
The ISEE test format is consistent across Lower, Middle, and Upper Levels: four scored multiple-choice sections followed by an unscored essay. Every multiple-choice question has four answer choices, each section includes a few unscored trial questions, and there are two scheduled 10-minute breaks.
The four scored ISEE test sections measure different skills in a deliberate order. Verbal Reasoning tests vocabulary and reasoning through synonyms and sentence completions. Quantitative Reasoning tests mathematical reasoning without heavy arithmetic — students often compare quantities or interpret data. Reading Comprehension uses short passages followed by multiple-choice questions. Mathematics Achievement tests computational and procedural math aligned to grade-level curriculum.
Sections always appear in the same order: Verbal Reasoning, Quantitative Reasoning, Reading Comprehension, Mathematics Achievement, then the 30-minute essay, with two scheduled 10-minute breaks. The Middle and Upper Levels share the same structure: 160 multiple-choice questions in 130 minutes, plus the essay, for 2 hours 40 minutes of testing. The Lower Level has 127 questions in 110 minutes plus the essay (2 hours 20 minutes).
| Section | Questions | Time |
|---|---|---|
| Verbal Reasoning | 40 | 20 minutes |
| Quantitative Reasoning | 37 | 35 minutes |
| Reading Comprehension | 36 | 35 minutes |
| Mathematics Achievement | 47 | 40 minutes |
| Essay (unscored) | 1 prompt | 30 minutes |
| Lower Level section | Questions | Time |
|---|---|---|
| Verbal Reasoning | 34 | 20 minutes |
| Quantitative Reasoning | 38 | 35 minutes |
| Reading Comprehension | 25 | 25 minutes |
| Mathematics Achievement | 30 | 30 minutes |
| Essay (unscored) | 1 prompt | 30 minutes |
The essay is not scored. Students handwrite it on the paper test and type it on the online test, and a copy goes to every school that receives the score report (families don't get a copy). Admissions offices read it to evaluate organization, grammar, and authentic student voice — the things they cannot see from multiple-choice scores. A thin, careless essay can erode an otherwise strong score profile, so timed practice matters even without a point value.
ISEE scoring explained in one sentence: every correct answer becomes one raw point, raw points become a scaled score from 760 to 940, that scaled score becomes a percentile against same-grade peers, and the percentile becomes the 1-9 stanine that admissions committees actually read. Each section is reported with all three scores.
A raw score is simply the count of correct answers. Students earn 1 point for each correct answer and 0 for incorrect or blank responses — there is no penalty for guessing. This single rule should change test-taking behavior: there is never a reason to leave a question blank, even with 10 seconds left on the clock. A random guess has a 25% chance of being right; a blank has 0% chance.
Scaled scores on each ISEE section range from 760 to 940. E3n uses a statistical process called equating to convert each test form's raw score into the scaled score, which adjusts for small difficulty differences between versions of the test. A student who sees a slightly harder form can earn the same scaled score as a student on an easier form with more correct answers — equating makes these outcomes comparable.
Each scaled score is converted to a percentile by comparing the student to all other same-grade ISEE test-takers from the last three years. A 7th-grade applicant at the 75th percentile performed as well as or better than 75% of 7th-grade applicants over that window. Because the ISEE test-taker pool is already self-selected (families preparing for private school admissions), a 50th percentile here sits well above the 50th percentile of the general student population.
Stanines compress percentile ranges into a simple 1-to-9 scale, and this is the number most admissions committees read first. A stanine of 5 sits at the middle of the pool (40th-59th percentile), stanine 7 covers the 77th-88th percentile, and stanine 9 is the top 4% (96th-99th). Because middle stanines span larger percentile ranges than extreme stanines, a 1-point stanine shift at the high end (7 to 8) is a much bigger performance gap than a 1-point shift near the middle (5 to 6).
| Stanine | Percentile Range | What It Means |
|---|---|---|
| 9 | 96th-99th | Top 4% of the ISEE pool |
| 8 | 89th-95th | Very strong |
| 7 | 77th-88th | Above average |
| 6 | 60th-76th | Upper middle |
| 5 | 40th-59th | Middle of the ISEE pool |
| 4 | 23rd-39th | Lower middle |
| 3 | 11th-22nd | Below average |
| 2 | 4th-10th | Well below average |
| 1 | 1st-3rd | Bottom 3% |

Worked Example — Raw Score to Stanine
Setup: A 7th-grade student takes the Middle Level ISEE and answers 32 out of 40 Verbal Reasoning questions correctly. How does that raw score become the number that admissions officers actually see?
The question "what is a good ISEE score" has no single answer because the right target depends on the schools a family is applying to. Still, there is a clean benchmark: the ISEE test-taker pool already skews toward strong students, so the middle stanines (4-6) represent solid performance in absolute terms, and stanine 7+ is the range selective schools typically target.
A stanine of 5 is the mathematical midpoint of the pool — the 50th percentile of same-grade test-takers. Because this pool is self-selected, a stanine 5 is not a mediocre score in the broader student population; it means the student is performing at the median of families who are actively preparing for private school admissions. Stanine 5 is acceptable at many independent schools.
A stanine of 7 is the 77th-88th percentile, and stanines 7 to 9 together are the top 23 percent of the ISEE pool. Selective schools often hope to see 7s or higher, but E3n publishes no cutoffs and every school weighs scores differently, so ask each admissions office what its admitted students typically score. An 8 or 9 (89th percentile and up) signals top-decile performance in that section.
Only about 4% of test-takers score stanine 9 in any given section, and the next 7% score stanine 8. Chasing a 9 across all four sections is statistically very rare and rarely the right study investment. A consistent 7-8 profile with a strong essay and transcript typically opens the same admissions doors as a 9, with less stress and less tutoring cost.
Many private schools accept either the ISEE or the SSAT, which leaves families wondering which test is better suited to their student. The answer usually comes down to school type, scoring rules, and how much math matters in the overall score.
Private day schools often accept or prefer the ISEE. Boarding schools more frequently request or prefer the SSAT. When a target school accepts either test, look at which one more of its admitted students historically submit — many schools will share this informally during interviews.
The ISEE has no guessing penalty. The Middle and Upper Level SSAT subtracts a quarter point for each wrong answer (the Elementary SSAT doesn't), which changes strategy on questions the student can't narrow down. On the ISEE, families choose which score reports to share, but only a complete report can be sent: sections from different ISEE tests can't be combined.
ISEE has two math sections (Quantitative Reasoning and Mathematics Achievement) that together make up 50% of the score. The SSAT has one math section worth about one-third of the score. For strong math students, the ISEE weighting can be an advantage; for stronger verbal students, the SSAT often feels more balanced.
| Feature | ISEE | SSAT |
|---|---|---|
| Typical school preference | Private day schools | Boarding schools |
| Guessing penalty | No | Middle/Upper: -1/4 per wrong answer; Elementary: none |
| Math weighting | Two sections / 50% of score | One section / ~33% of score |
| Tests allowed per year | 3 (one per season) | More: standard paper dates plus limited Flex, at-home and Prometric sittings |
| Combining sections across tests | Not possible (complete reports only) | Depends on each school's policy |
| Writing sample | Unscored essay sent to schools | Unscored writing sample sent to schools |
| Primary starting grade | Grade 2 entry | Grade 4 entry |
ISEE registration runs through your ISEE account. Test seasons are spaced to give families multiple chances to get the score they need, and cost depends on the format and host.
There are three ISEE testing seasons each admissions year: Fall (August through November), Winter (December through March), and Spring/Summer (April through July). A student can take the ISEE once per season, for a maximum of three times per admissions year. See our ISEE test dates for 2026-27 for the current calendar.
For 2026-27, the Lower, Middle and Upper Level ISEE costs $170 at a member school or in school-run at-home testing, $225 in a testing office (small group), $250 at a Prometric center or in E3n-run at-home testing, and $255 for individual office testing. Primary levels cost $130 to $210. Late registration for a paper test adds $45 and walk-in testing adds $60. Full details: ISEE registration fees.
Families can test at home (online), at a member school (paper or online), in a testing office (paper or online), or at a Prometric center (online, grades 5-12 only). Standard registration for a paper test closes 21 days before the test date, with late registration from 20 to 14 days out; online tests can be booked up to 3 days before. Choose the format that best matches the student's testing habits — some students focus better on paper, others prefer a keyboard.
Good ISEE prep is less about cramming and more about repeated, structured practice over a two-to-three-month window. Because the ISEE tests a wide range of skills — vocabulary, reading comprehension, reasoning, and curriculum math — short, frequent sessions beat weekend marathons every time.
Most tutors recommend starting 2 to 3 months before test day with 4 to 6 hours of focused prep each week. A longer 4 to 6 month timeline works well for students targeting top-tier schools or students who need to build vocabulary. Short, frequent practice sessions are far more effective than last-minute cramming.
Estimate how many prep hours a student should complete before test day, based on weeks available and target stanine.
Vocabulary is the single biggest lever on Verbal Reasoning: many tested words are above grade level, and a student who has never met a word can rarely reason their way to its synonym. Our ISEE vocabulary list has words by level. On the two math sections, write calculations down rather than doing them mentally; careless errors are a bigger score drag than not knowing a concept. On Reading Comprehension, read actively by summarizing each paragraph in a couple of words before moving to the questions.
At least two full-length timed practice tests should appear in any prep plan. The Middle and Upper Level ISEE run about 3 hours with breaks, and fatigue and pacing cost students points on test day. Simulate real conditions, including the two 10-minute breaks, and always answer every question because there is no guessing penalty. Start with our free ISEE practice test.
