ExploreAbout this exam
The Independent School Entrance Exam (ISEE) is an admission assessment published by ERB, a not-for-profit, member-based organization with a long history of serving independent schools. According to ERB, the ISEE is accepted by over 1,200 independent schools around the world and is described as a trusted and predictive admission assessment for students in Grades 2–12. Families register for the ISEE through ERB, and ERB also publishes guidance on understanding ISEE scores.
The ISEE includes a Mathematics Achievement section, which is the focus of this page. Mathematics Achievement tests grade-appropriate math skills through multiple-choice questions rather than a single mixed problem set; the section is one component of the broader ISEE battery, alongside other verbal, quantitative, reading, and writing components described by ERB. Candidates should confirm section structure, timing, and scoring details for their grade level directly with ERB, because published details can change.
This page is an independent study resource. It is not affiliated with, endorsed by, or sponsored by ERB or E3n, and it does not reproduce official test materials. Preparation should combine review of grade-level math content, timed practice with multiple-choice formats, and careful error analysis. Note that ERB and EMA have completed a merger and now operate as E3n; ISEE remains an ERB-registered trademark.
What you'll study
About ISEE Math Achievement preparation
Who publishes the ISEE, and is this page official?
The ISEE is published by ERB, which states that CTP and ISEE are registered trademarks of ERB. ERB and EMA have completed a merger and now operate as E3n. This page is an independent study resource and is not affiliated with, endorsed by, or sponsored by ERB or E3n.
Which grades does the ISEE serve?
ERB describes the ISEE as an admission assessment for students in Grades 2–12 and as the most predictive, trusted, and flexible admission assessment for students entering Grades 2–12. Because test levels differ by grade, confirm the level that applies to your child with ERB before registering.
How many questions are on Mathematics Achievement, and how long is it?
We do not have a verified current figure for the number of Mathematics Achievement questions or its time limit from the source material available to us, so we do not state one. Check ERB's official ISEE materials for your test level, since section structure and timing can change between administrations.
What math content should I study?
Focus on grade-level mathematics: number and operations, fractions and decimals, ratios and percents, algebraic reasoning, geometry and measurement, data interpretation, and multi-step word problems. ERB notes its achievement assessments cover mathematics among other domains. Build accuracy first, then speed, and review every missed item to find the underlying concept gap.
How is the ISEE scored, and what is a good score?
ERB publishes guidance on understanding ISEE scores, and score reports are best interpreted through that official guidance rather than fixed cutoffs. There is no universal passing score; independent schools set their own expectations. We do not publish a passing threshold because ERB does not state one in the source material available to us.
Can I retake the ISEE?
We could not verify ERB's current retake policy from the source material available, so we do not state retake limits, waiting periods, or fees. Retake rules are set by ERB and can differ by testing season and format. Confirm directly with ERB before planning a second attempt, and treat the first sitting as the one that matters.
How much does the exam cost?
We do not have a verified current fee from the source material, so we do not quote one. Fees can vary by registration type, testing location, and timing, and ERB lists refund policies on its site. Check ERB's registration pages for the current fee before you pay, and register early to avoid late charges.
How should I order my Mathematics Achievement preparation?
Start with a timed diagnostic to expose weak topics. Then work topic by topic, redoing missed problems until the method is automatic. Add mixed sets so you practice choosing strategies, not just applying one. Finish with full-length timed practice under realistic conditions and a short review of your error log the day before the test.
What are the most common mistakes candidates make?
Rushing multi-step word problems, skipping the question's actual ask, misreading units, and guessing instead of eliminating answers. Weak arithmetic fluency also causes errors under time pressure. Another frequent failure is practicing only familiar topics; candidates should deliberately drill the areas their diagnostic flagged as weakest.
Where can I find official ISEE information?
Use ERB's own site, erblearn.org, for registration, score interpretation, and current test details, and note that ERB now operates alongside E3n following the merger with EMA. Some previously published ISEE family pages currently return errors during the site transition, so use ERB's search or contact its support team if a link fails.
