Mark Schemes: SAT Scaled Scores
A pupil’s scaled score is based on their raw score. The raw scores for each test are calculated by adding the scores from each paper for a subject.
At KS1: 85 is the lowest scaled score that can be awarded on a KS1 test. The highest scaled score is 115. At KS2: 80 is the lowest scaled score that can be awarded and 120 is the highest scaled score.
A pupil awarded a scaled score of 100 or more has met the expected standard. Pupils with a scaled score of 99 or less have not met the expected standard.
The threshold for a high score in 2016 has been set at 110 (source, p1)
Pupils need to achieve a minimum raw score in order to demonstrate sufficient understanding of the curriculum and be awarded a scaled scores. Pupils who do not meet this minimum will receive no scaled score (N).
Pupils do not receive a scaled score for writing, which is assessed by teacher assessment. However, points are allocated to the writing teacher assessments for the purposes of statistical analysis as below (source, p18):
