How are the school assessment scores moderated?
The mean (average) and standard deviation (spread of scores) of the English and mathematics tests are calculated for all of the students from each primary school who sat the test.
The mean and standard deviation are applied to the school assessment scores for English and mathematics.
What happens to the test scores?
For each test component, the test score is scaled to a mean of 60 and a standard deviation of 12. In other words the average score correct out of 20 for English is scaled to 60 out of 100 and all other scores are calculated relative to that score of 60. The process does not convert the test score to a percentage score.
What happens next?
The rest of the score processing averages the scaled school assessment scores and the scaled test scores for English and mathematics, rescales them to a mean of 60 and a standard deviation of 12 and adds the scaled general ability score. The three scores out of 100 are combined to make the calculated profile score out of 300. The average score of the candidature is therefore always set to 180.
