Overview of the ISEE Test
The ISEE test, also known as the Independent School Entrance Exam, is used by private elementary, middle, and high schools to evaluate the core academic skills of their applicants. The exam is administered by the Educational Records Bureau (ERB) and covers students in grades two through 12 with unique tests for different grade levels. The ISEE levels are:
- Primary for entrance in grades two through four
- Lower for grades five and six
- Middle for entrance in grades seven and eight
- Upper for entrance in grades nine through 12
All levels of the ISEE test cover the same four core competencies—Verbal Reasoning, Quantitative Reasoning, Reading Comprehension, and Mathematics Achievement—however, the material and format vary depending on the group level given the test. Additionally, those taking the Lower, Middle, and Upper ISEE test are also given an essay question to answer.
What is Tested on the ISEE?
To score well on the ISEE, it’s important to understand its five sections and what they’re testing.
- Verbal Reasoning: Evaluates a student’s vocabulary and problem-solving ability with questions about synonyms and sentence completion.
- Quantitative Reasoning: Assesses a variety of math concepts such as algebra, geometry, and statistics with word problems and quantitative comparisons.
- Reading Comprehension: Tests reading skills such as identifying main and supporting ideas, vocabulary, structure, and tone. Students will read passages on humanities, science, and social studies and answer accompanying questions.
- Mathematics Achievement: Covers skills such as algebra, geometry, measurement, and data analysis and probability.
- Essay: Students are given a prompt and tasked with writing a well organized and informed essay. The essay is not scored, but is given to the schools a student applies to and used as a writing sample.
How Long is the ISEE?
The upper- and middle-level ISEE tests share the same structure and timeframe, although the upper-level exam features more challenging questions. Below is a look at the format and time limits of the two exams:

ISEE Test Dates
The ISEE test dates are available throughout the year with the majority of them scheduled in the fall and early winter. The ISEE divides its test dates into three periods and a student is only allowed to take the exam once per period. The ISEE test date periods are:
- Fall: August through November
- Winter: December through March
- Spring/Summer: April through July
ISEE test dates are easily searchable on the ERB’s website.
How is the ISEE Test Scored?
Every question on the ISEE is of equal value and there is no penalty for wrong answers; consequently, test takers should answer every question, even if it means guessing. ISEE scores are represented in three ways: a scaled score, a percentile score, and a stanine score.
- Scaled Score: Raw scores are converted into a scaled score between 760 and 940.
- Percentile Score: Shows how the student compares against a “norm group,” which is made up of students who took the same test, for the same age group, over the past three years. The higher a student’s percentile score (the scale is 1% to 99%), the better they did on the exam.
- Stanine Score: This is the score commonly used by admissions departments. Stanines group percentage ranges into a nine-point scale. The distribution of scores into stanines remains consistent year to year—only 23% score between a seven and nine and only 23% score between a one and a three. Just 4% of students achieve a nine!
Below is a look at how the ERB transforms percentiles ino stanines.
