Common questions
What is a good KS2 SATs scaled score?
100 or more means a pupil met the expected standard. Scores run from 80 to 120, and many schools and the government's own statistics treat 110 or more as working at a higher standard.
How many marks did you need for 100 in 2026?
English reading: 25 out of 50; Mathematics: 56 out of 110; English grammar, punctuation and spelling: 34 out of 70.
Why does the conversion change every year?
Each year’s tests are different, so the Standards and Testing Agency sets a new table after marking, to make 100 mean the same standard whichever year a child sat the tests.
Can I use this for a practice paper at home?
Yes, as a guide: add up the marks across the papers for the subject and use the table for the same year as the paper. A score from a practice paper at home is not the same as sitting the test in school.
