Stonar School has been placed among the top 1.5% of 400 schools across the country in a nationwide value-added assessment of GCSE grades in 2020.  

Using CEM, one of the largest providers of formative assessments, schools collect baseline data from their pupils which can be used to measure their progress as they advance through their Senior School years. The assessments can help teachers understand what pupils know and can highlight where they need support.

The assessments also predict GCSE and A level grades. In its 2020 results, Stonar’s GCSE pupils gained an average value-added score of +1.5 grades per subject, per pupil, while its A level pupils gained 0.8 above predictions (equating to the top 2.5% nationally of CEM schools).  

Matthew Way, Headmaster, commented, “This means on average every Stonar pupil achieved a grade or more above base, in each subject, than other pupils of the same ability across the country. Value-added measures are intended to offer a better indication of the progress that pupils have made. Rather than relying solely on exam results, they take account of where each pupil started and the progress they made relative to other, similar pupils. We know that part of what is captured by value-added figures reflects the genuine impact of a teacher on pupils’ learning.”
