Understanding Progress 8 and Attainment 8
Progress 8 and Attainment 8 are the new measures of GCSE results.
Attainment 8 is calculated by translating GCSE grades into numbers. An A* is worth eight and an A is worth seven, and so on down to G, worth one point.
Next, the subjects are divided into categories, known as buckets. The first bucket holds maths and English, which are each given double weighting. The second bucket contains the English Baccalaureate subjects: the three best grades from sciences, languages, geography or history. Then there is bucket three, which includes the three best grades achieved in other Ebacc or approved qualifications, including vocational or arts subjects. The grades, converted to points, are then divided by 10, and that average is a student’s Attainment 8 score.
A student’s Progress 8 score is derived by comparing their forecast Attainment 8 score – based on the results achieved by pupils with the same prior attainment at key stage 2 (Primary School) – to their Attainment 8 score.
For example: a student expected to get straight Cs would need to have a score of 50 to meet their Progress 8 target. If they do better and get Bs or As, they will have a positive Progress 8 score that will improve their school’s average. Similarly a pupil expected to get Es and Fs would improve their school’s score if they instead attain Ds.
A pupil forecast to gets As would lower their school’s Progress 8 average if they instead get Bs.
Therefore, a school-wide Progress 8 score of -0.5 would indicate the school’s average achievement is half a GCSE grade below the national average of other pupils with the same expected progress.
It is difficult to say with certainty how much of the Progress 8 score is down to the school(which may have scored higher with a different group of pupils) and how much is down to the pupils(for example some may have performed well at any school).The confidence interval reflects this uncertainty.If the confidence intervals for two schools overlap, then we can't say for certain that the two Progress 8 scores for these schools are significantly different.
