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.
Alongside 444 UK maintained and independent schools Walthamstow Hall submits data to the Centre for Evaluation and Monitoring at Durham University (CEM) each year. They use the data to produce value added scores and a ranking for each school.
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, the school submits the second set of data, the final A Level grades of each student. The two sets of data, i.e. actual versus predicted grades are overlaid and the different between the two gives the value added score.
Value added scores are a fantastic indicator of the quality of a curriculum and the teaching which delivers it.
Walthamstow Hall consistently achieves high value added scores, with students gaining higher than expected grades.
In 2019, Walthamstow Hall was ranked in the top 24% of schools nationally for A Level value added.
