At the end of Key Stages 1 and 2, all children in years 2 and 6 sit Statut0ry Assessment Tests (SATs). The way that the results are calculated, changed in 2016 in line with the new National Curriculum and higher expectations.
Children in year 2 are recorded as having met or not met the expected standard in reading, writing and maths. In KS2, the children are recorded as having met or not the standards in reading, writing, grammar, spelling and punctuation, and mathematics. There are also scaled scores for reading, grammar and maths with 100 being the expected standard. These scaled scores relate to the raw scores achieved on the actual tests – in 2017, 100 in reading was equivalent to a raw score of 26, and in 2016 it was equivalent to a raw score of 21.
Progress for KS2 is measured using the children’s KS1 scores which are converted into points and an average of reading, writing and maths is used to plot the expected progress for each child based on the average KS1 score.
For example: L2b at KS1 = 15pts so if a child achieved L2b (15pts) in reading and L1 in writing (9pts), the average for English would be 15 + 9 = 24 ÷ 2 = 12, with maths at L2c = 13. Add the average for English (12pts) to the maths points (13pts) and find the average: 12 + 13 = 25, 25 ÷ 2 = 12.5. Using this figure and the chart produced by the Department for Education, a child who averaged 12.5pts at KS1 is expected to achieve 95.8 in reading, 94.2 in writing and 97.7 in maths.
These figures are to identify the progress of each child by comparing their scaledscore on the test to the predicted score. For example, a child who achieved 100 on the reading test and was predicted 94, shows progress of +6; a child who achieved 96 but was predicted 102, shows progress of -6.
Hopefully, this helps you to interpret the data for KS2. Please follow the link below to see this year’s results.
