ISEB (Independent Schools Examinations Board)

Used by many independent schools

About ISEB

ISEB assessments are used by many independent schools, and come in two distinct forms.

The ISEB Common Pre-Test is an adaptive online assessment — the difficulty of each question adjusts based on previous answers — covering English, Mathematics, Verbal Reasoning and Non-Verbal Reasoning.

The ISEB Common Entrance is more curriculum-based, sat later, and may include subjects such as Science and Humanities alongside English and Mathematics.

Because the Pre-Test is adaptive, consistent accuracy matters more than speed alone — a wrong answer early on can shift the difficulty of the rest of the test.
