Value Added

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 Press & Assessment each year. They use the data to produce value added scores and a ranking for each school.  The first set of data is submitted when pupils join their senior school in Year 7, and when they join Year 12; at these stages the pupils complete a Cognitive Ability Test (respectively called MidYIS and ALIS) which provides a baseline of their natural ability in different areas. CEM uses this data to predict the likely GCSE and A Level outcomes for each pupil.  When the school submits the second set of data, the final I/GCSE and A Level grades of each pupil, the two sets of data of actual versus predicted grades are overlaid and the difference between the two gives the value added score.

For GCSE, our value added score in 2023 placed Walthamstow Hall comfortably within the top 10% of the independent sector, and 2022 saw the best result we have ever achieved, ranked within 3%.

For A Level, in 2023 we were ranked in the top 6% of independent and state sector schools.  This is a fantastic achievement and is our best since 2015, discounting the pandemic years of 2020-1 when exams were assessed differently.

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 pupils gaining grades higher than the grades predicted for them.
