The ISEE Primary Level is the version of the Independent School Entrance Exam taken by students applying to grades 2, 3, and 4 at private and independent elementary schools. This guide breaks down exactly what's on Primary 2, Primary 3, and Primary 4 — including question counts, timing, scoring, and a realistic prep plan for young learners.
The ISEE Primary Level is the entry-grade version of the Independent School Entrance Exam, administered by E3n (formerly ERB, the Educational Records Bureau). It is the test of choice for many independent and private schools that admit students into the early elementary grades, and choosing the ISEE for elementary school admissions is a step a lot of NYC, Boston, and Bay Area families take in the fall before their child applies.
Each Primary Level is named for the grade your child is applying to enter. Primary 2 is for current first graders applying to second grade, Primary 3 is for current second graders applying to third grade, and Primary 4 is for current third graders applying to fourth grade. Always register based on the grade your child wants to start in the next school year, not the grade they are in now.
Schools see the Primary Level as one signal among many. Because students this young have less academic history, the Primary score helps admissions teams compare reading and math readiness on a common scale across applicants from different preschools and elementary programs. It is rarely used as a strict cutoff at this age — most schools weigh teacher recommendations, parent interviews, and the on-site visit at least as heavily.
The Primary Level is delivered on a computer, either at one of E3n's testing sites, a member school, or at home with a remote proctor. Children answer everything by clicking a mouse or tapping a screen — there is no paper bubble sheet or written response. That alone is a meaningful adjustment for kids who don't normally use a computer for tests, which is why most prep guides recommend at least a few mock sessions on a real device.
Choose the grade your child is applying to enter, then see which Primary Level they should register for.
The Primary Level ISEE format is built around two or three multiple-choice sections, depending on which level your child takes. Every question presents four answer choices, and there is one short break between Reading and Math so children can stretch and refocus.
Across the three Primary Levels you'll find at most three sections. Auditory Comprehension appears only on Primary 2 — students listen to a short passage and then click answer choices on the next screen. Reading is independent silent reading on every level, and Mathematics is calculator-free with arithmetic, basic algebra, geometry, and word problems suited to the applying-to grade.
Total testing time is 53 minutes for Primary 2, 54 minutes for Primary 3, and 60 minutes for Primary 4. Each test also has a 5- to 10-minute break between Reading and Math. Plan for the full appointment to run roughly 75-90 minutes once you include check-in, instructions, and the break.
| Section | Primary 2 (Grade 2) | Primary 3 (Grade 3) | Primary 4 (Grade 4) |
|---|---|---|---|
| Auditory Comprehension | 6 questions / 7 min | — | — |
| Reading | 18 questions / 20 min | 24 questions / 28 min | 28 questions / 30 min |
| Mathematics | 24 questions / 26 min | 24 questions / 26 min | 28 questions / 30 min |
| Break | 5-10 min | 5-10 min | 5-10 min |
| Total testing time | 53 minutes | 54 minutes | 60 minutes |
Two things parents often expect — and won't see. First, there is no calculator allowed on any Primary Math section, so make sure your child is comfortable doing simple arithmetic on paper or in their head. Second, the Primary Level no longer has a writing sample. The essay was discontinued for Primary Levels starting in the 2021-2022 testing season, so the test today is entirely multiple choice.
ISEE Primary 2, ISEE Primary 3, and ISEE Primary 4 share the same general look and feel, but the section list, question counts, and total time all step up as the level rises. Knowing the differences helps you focus prep on the right skills for your child's level.
Only Primary 2 includes the Auditory Comprehension section, where children listen to a passage they cannot see and then answer questions about it. Primary 3 and Primary 4 drop this section entirely and consist only of Reading and Mathematics. That makes Primary 2 the most multimodal Primary Level — it tests listening skills that the other levels do not.
Reading scales up across the levels: Primary 2 has 18 questions across three passages, Primary 3 has 24 questions across four passages with six questions each, and Primary 4 has 28 questions across four passages with seven questions each. Math grows from 24 questions in Primary 2 and 3 up to 28 questions in Primary 4, and the math content shifts toward larger numbers, more multi-step problems, and slightly more abstract reasoning.
Three things ratchet up between Primary 2 and Primary 4. Reading passages get longer and use more sophisticated vocabulary, math problems shift from single-step computation toward simple word problems and basic geometry, and the test itself adds about seven minutes from the shortest level to the longest. None of those jumps are dramatic, but they're enough that practicing on your child's specific level matters.
ISEE Primary scoring uses three numbers: scaled scores, percentile ranks, and stanines. The scaled scores are unique to each Primary Level, while percentiles and stanines are calibrated against the same-level cohort from the past three years.
Each Primary Level uses its own scaled score range. Primary 2 reports scaled scores from 200 to 299, Primary 3 from 300 to 399, and Primary 4 from 400 to 499. This is different from the Lower, Middle, and Upper Level ISEE, which all use a 760-940 per-section scale. The Primary scale was designed so a Primary 2 score and a Primary 4 score are easy to tell apart at a glance.
| Primary Level | Applies To | Scaled Score Range | Lowest Stanine 1 | Top Stanine 9 |
|---|---|---|---|---|
| Primary 2 | Applying to grade 2 | 200-299 | Bottom 4% | Top 4% |
| Primary 3 | Applying to grade 3 | 300-399 | Bottom 4% | Top 4% |
| Primary 4 | Applying to grade 4 | 400-499 | Bottom 4% | Top 4% |
Stanines compress the percentile scale into nine bands from 1 (lowest) to 9 (highest), with 5 as the midpoint. Schools usually look at the stanine first because it groups similar performers together — a percentile of 65 and a percentile of 70 are both stanine 6, and admissions teams treat them as roughly equivalent.
The distribution is engineered to be steady year over year: about 54% of test takers score in the stanine 4-6 band, while 23% score above and 23% score below. The table below shows how each stanine band maps to an approximate percentile range.
| Stanine Band | Description | Approximate Percentile Range | Share of Test Takers |
|---|---|---|---|
| 1-3 | Below average | 1st-22nd | About 23% |
| 4-6 | Average to above average | 23rd-76th | About 54% |
| 7-9 | Well above average | 77th-99th | About 23% |
At the Primary Level, most schools use scores as a sanity check rather than a hard cutoff. They want to confirm that a child's reading and math foundations match the grade they're entering. Stanines of 5 and above usually clear that bar comfortably, and stanines below 4 might prompt a second look at supporting documents or an academic interview.
Worked Example
Setup: Imagine a student takes the Primary 3 ISEE and answers 38 of 48 multiple-choice questions correctly across the Reading and Mathematics sections.
Because the test is age-appropriate, every question uses simple, child-friendly language and presents exactly four answer choices. Below is a quick tour of the section types, followed by a few practice questions you can try with your child.
Students hear a short passage through headphones (no on-screen text), then six questions appear with four answer choices each. The questions test main idea, supporting detail, vocabulary, and simple inference. Because the passage is gone before the questions appear, listening attention is the most important skill.
Reading uses both fiction and nonfiction passages of about a paragraph each. Question types include main idea, supporting detail, vocabulary in context, organization, and simple inference. Primary 2 has three passages, Primary 3 has four, and Primary 4 has four longer passages with seven questions per passage.
Math draws from grade-level standards: number sense, simple arithmetic, place value, basic algebra patterns, geometry, measurement, and word problems. Calculators are not allowed on any Primary Level. Expect a mix of pure computation and lightly contextual word problems.
Pick the Primary Level your child is taking to see the average time per question on each section.
ISEE Primary scoring is generous to students who simply feel calm, focused, and familiar with the format. The most effective prep at this age is short, frequent, and varied — not heavy drilling.
Most prep specialists recommend planning 3-6 months of light practice before test day. Short, frequent sessions over several months are much more effective than a few long sessions in the days leading up to the test. Twenty focused minutes a day is enough at this age, and consistency matters more than total hours.
Every ISEE registrant gets free access to the official ISEE practice test, including personalized feedback. E3n also publishes free, online sample tests that mirror the look and feel of the real online ISEE. Use these first — they are the most accurate practice your child will get.
For Reading, read with your child every day and ask one or two questions about the main idea, a small detail, and a tricky word. For Math, focus on number sense, basic addition and subtraction facts, place value, and simple geometry vocabulary. For Auditory Comprehension on Primary 2, occasionally read a short story aloud without showing the page and then ask a few questions.
The ISEE Primary Level is delivered on a computer, which is unfamiliar territory for many young children. Run at least one or two practice sessions on a real computer with a mouse or trackpad so your child knows how to click an answer choice and move forward. The pacing calculator above shows roughly how many seconds per question they should target.
| Month | Reading Focus | Math Focus | Practice Activity |
|---|---|---|---|
| Month 1 | Read aloud daily; main idea questions | Number sense and basic arithmetic | Untimed sample questions, 10-15 min/day |
| Month 2 | Independent reading; inference questions | Geometry, measurement, word problems | Two timed mini-sections per week |
| Month 3 | Mixed fiction/nonfiction passages | Mixed review and trouble spots | One full-length practice test under test conditions |
Registration for the Primary Level happens at ERBlearn.org. Online testing slots are typically available up to 3 days before the test, while in-person and paper formats need to be booked further out — register early to avoid late fees and limited seat availability.
Create a parent account at ERBlearn.org, choose your testing window, and pick the Primary Level that matches the grade your child is applying to enter. You'll select either an at-home online appointment, a member-school administration, or a testing-office appointment depending on what's available in your region.
Fees range roughly $125-$185 depending on testing format and location: about $125 for an online registration at a member school or a school-administered at-home test, around $155 for an ISEE-administered at-home test, and about $180 for in-office testing. Phone registration adds approximately $30. E3n also publishes fee waivers for qualifying families, which include free access to the official ISEE prep package.
The full appointment usually runs 75-90 minutes, including check-in, instructions, the test itself, and the break. For at-home testing, you'll need a working camera, microphone, and a stable internet connection. Children should have a quiet, well-lit testing space and a parent nearby for setup but not for the test itself.
