Value Added is the independently verified statistical measure which many schools in the UK, including Walthamstow Hall, use to track the academic progress of students from Year 7 to Year 11 and again from Year 12 to Year 13.
Alongside many other UK maintained and independent schools Walthamstow Hall submits data to the Centre for Evaluation and Monitoring (CEM) at Cambridge University each year. They use the data to produce value added scores and a ranking for each school.
Value Added at A Level
To assess value added at Sixth Form, schools provide CEM with two sets of data, two years apart. The first set of data is submitted when students join Year 12. At this stage, the students complete a Cognitive Ability Test, called ALIS, which provides a baseline of their ability in different areas. CEM uses this data to predict the likely A Level outcomes for each student. Two years later, schools submits the second set of data i.e. actual versus predicted grades are overlaid and the difference between the two gives the value added score.
From 2017-2020 Walthamstow Hall has appeared within the 73rd percentile of Independent Schools for value added at A Level, i.e. at least 73% of Independent Schools in the CEM sample have lower value added scores. In 2021 the value added result was high and statistically significant, and positioned us in the 99th percentile, as was the case in 2020.
