The ISEE Quantitative Reasoning section consists of 37 questions (32 scored, 5 unscored) to be completed in 35 minutes on the Middle and Upper Level exams, administered by ERB (Educational Records Bureau). Approximately 15 of the 37 questions are quantitative comparisons, with the remainder being word problems covering numbers & operations, algebra, geometry, measurement, and data analysis. The four standard answer choices for quantitative comparisons are: Quantity A is greater, Quantity B is greater, The two quantities are equal, and The relationship cannot be determined from the information given. Calculators are NOT permitted; scratch paper is allowed. (Source: ERB What to Expect on the ISEE, 2018.)

About the ISEE Quantitative Reasoning Exam
The ISEE Quantitative Reasoning section tests mathematical thinking, not computation speed. The Middle and Upper Level exams each present 37 questions in 35 minutes, combining word problems with unique quantitative comparison questions. Quantitative comparisons ask students to compare two quantities and select which is greater, if they are equal, or if the relationship cannot be determined — a format requiring careful reasoning rather than rote calculation.

Frequently Asked Questions
What is a quantitative comparison question on the ISEE?
A quantitative comparison question presents two quantities (Quantity A and Quantity B) and asks you to determine their relationship. The four answer choices are always: (A) Quantity A is greater, (B) Quantity B is greater, (C) The two quantities are equal, and (D) The relationship cannot be determined from the information given. These questions appear only on the Middle and Upper Level ISEE.
How many questions are in the ISEE Quantitative Reasoning section?
The Middle and Upper Level ISEE Quantitative Reasoning section contains 37 questions total — 32 are scored and 5 are unscored experimental questions. You have 35 minutes to complete all 37 questions, which averages to about 57 seconds per question.
Can I use a calculator on the ISEE Quantitative Reasoning section?
No. Calculators are not permitted on any section of the ISEE. However, scratch paper is allowed — students taking the paper test may use the blank space in the test booklet, while online test takers receive up to four sheets of scratch paper.
What math topics are tested on ISEE Quantitative Reasoning?
The section covers numbers and operations (fractions, decimals, percentages, ratios), algebra (variables, equations, inequalities, patterns), geometry (area, perimeter, volume, angles, coordinate geometry), measurement, and data analysis and probability. Questions emphasize reasoning ability over computation.
What is the difference between ISEE Quantitative Reasoning and Math Achievement?
Quantitative Reasoning tests HOW you think mathematically — it rewards reasoning, pattern recognition, and logic, with minimal calculation required. Math Achievement tests WHAT you know — it covers more curriculum-based math and requires more direct computation. Both appear on the ISEE.
How is the ISEE Quantitative Reasoning section scored?
Raw scores (number correct) are converted to a scaled score (760–940) and then to a stanine (1–9). There is no penalty for wrong answers on the ISEE, so you should always guess if you are unsure. Each school uses stanine rankings differently to make admissions decisions.
