ISEE guide

Which ISEE level?
It follows the grade applied to.

The most common mistake families make with the ISEE is preparing at the wrong level — because the level follows the grade being applied to.

Last verified 5 August 2026. Level definitions follow ERB's published ISEE structure.

The rule

The ISEE has three levels used for grades 5 through 12. The level is set by the grade your child is applying to, not the grade they are currently in.

LevelApplying toSat in
LowerGrades 5–6Grades 4–5
MiddleGrades 7–8Grades 6–7
UpperGrades 9–12Grades 8–11

A child in grade 7 applying for grade 8 sits the Middle Level. The same child applying for grade 9 sits the Upper Level. Same child, same autumn, different exam.

Why the mistake is costly

The levels are not the same paper with easier numbers. They differ in question count, in timing, and in what is tested.

LevelQuestionsTesting time
Lower127110 minutes
Middle160130 minutes
Upper160130 minutes

A student who prepares at the Lower Level and sits the Middle Level meets thirty-three more questions in twenty more minutes, on harder content. A student who over-prepares at the Upper Level wastes months on material that will not appear.

Middle and Upper look identical and are not

The Middle and Upper Levels have the same shape — same counts, same clock, same four sections. The difficulty is completely different. An Upper Level question is written for a student applying to high school; a Middle Level question is not.

This is why our ISEE practice exams are written separately for each level, with no question shared between them, rather than one bank served three ways.

The writing sample

Every level includes an unscored essay. It is not marked, but it is sent to the schools, who read it. Practicing it is worth an afternoon, not a month.

Next

Once you know the level, read what is actually on the ISEE for the four sections and their timings. ten free questions include ISEE questions at each level.

Practice the real thing

Our ISEE exams are full length and written from scratch — every wrong answer carries its own explanation, so a child learns what they got wrong and why. Ten questions are free, with no account and no card. After that it is five credits an exam.
