KS2 scaled scores: what 100 means

Each KS2 test gives a scaled score from 80 to 120. A score of 100 or more meets the expected standard. The raw marks needed for 100 can change from year to year, so the conversion tables are published after the tests.

From raw marks to a scaled score

The raw score is the marks from every paper in a subject added together, so maths adds Papers 1, 2 and 3. A pupil must sit each paper in the subject to get a scaled score, and needs a minimum raw score before the lowest scaled score is awarded.

What our practice tells you

Our free test and timed checks give marks by section, never a scaled score: they show which part of the course to work on next.

Questions people ask

What is the expected standard?

A scaled score of 100 or more in a test. A score of 99 or less has not met it.

Why does the pass mark change?

Each year's tests are different, so the raw marks needed for 100 can change; the scaled score keeps results comparable over time.
