Selective school maths tests: what parents need to know

What the tests actually assess

Selective-entry maths tests are designed to separate strong students from each other, so they lean on reasoning rather than recall: number patterns, spatial thinking, multi-step word problems, and questions where the method is the puzzle. Most children have the underlying knowledge — what they lack is exposure to the question styles and the tempo.

The three gaps that cost the most marks

First, reading load: many "maths" questions are really reading-comprehension questions with numbers, and slower readers lose time. Second, unfamiliar formats: mirror images, number machines, and sequence puzzles that never appear in school workbooks. Third, pacing: papers are deliberately long, and children who try to be perfect on every question run out of time.

All three are trainable — but only with realistic practice material and a timer. Worksheets without a clock fix none of them.

How much preparation is enough?

A calm rule of thumb for Years 4–6: two to three short practice sessions a week plus one timed paper a fortnight, starting three to six months out. More than that risks burnout and diminishing returns; the goal is a child who is familiar, fast and confident — not exhausted.

Track progress by topic rather than total score. A rising mastery trend in the two weakest areas predicts exam-day improvement far better than a single overall number.

Practise the way the test works

SimplyMaths gives your child timed mock exams in the selective-entry style, marks them instantly, and turns each paper into a skills map with a specific plan for the week. The first mock exam is free — a realistic baseline in under an hour.
