How is Value-added Measured?
Value-added is a measure of the progress pupils make over a period of time. Value-added takes into account how much progress a child has made since their starting point, compared to the progress they have made relative to similar pupils. It is designed to be a fair tool that focuses on measuring progress based on the individual rather than overall exam results in a school.
As a parent looking to make active choices about where their children should be educated, you may find the way school performance is measured tricky to evaluate. After all, if a school is academically selective, then of course they are more likely to measure high levels of progression and show top of the board for being one of the ‘best’ schools based on results. But, if we aren’t comparing like with like, then it isn’t an effective measure to evaluate true progress.
However, by using data from exam tests over the last decade, it enables schools to predict how well each group of children are likely to perform based on their tests results from the start of their school year. When they have taken their final exams, results can be compared with those expectations. If the individuals have done better than they expected, value has been added, if not then value has not been added.
Progression is subjective. We need to recognise how, perhaps for some pupils a Grade 4 at GCSE, is actually a really good performance where value has been added for that pupil.
