Academic Performance and 'Value Added'

Updated - June 2022

We use a range of internal and external, qualitative and quantitative, measures to assess the progress of each child and the overall value-added achievement of our pupils. We are very proud of the academic progress achieved by the Sandroyd children. 

Our academic curriculum ultimately aims to prepare children for Common Entrance and Scholarship exams. We believe both Common Entrance and Academic Scholarship provide robust ‘high stakes’ exit exams for the Sandroyd children. The knowledge and skills developed in our curriculum prepare children for the challenges required at GCSE and beyond. Above all through, we aim to inspire children to engender a love of learning.    

GL Assessment Data

Sandroyd uses GL Assessment Progress tests to track pupils' progress in a number of subjects over time. These external tests assess various skills and provide a standard age score (SAS). Nationally, the average score is 100 and is based on age related expectations.

If a pupil achieved a SAS score of 100 and then scores 100 the following year, they will have achieved progress in line with the national average. A horizontal trend line would represent this in the graph below. However, if this pupil had achieved a score greater than 100, then they would have made progress that is greater than expected.

Our bespoke database (Sandfly) analyses all of our pupils’ results on a biannual basis. We aim to significantly exceed progress compared to the national average. Our success is highlighted in the two graphs below, both showing positive trend lines over several years.

Common Entrance Results

Senior Schools can monitor academic progress based on GCSE, A-Level and IB results. This is harder to do at Prep Schools as Common Entrance is marked to different grade standards by the different senior schools we prepare the children for. However, alongside other assessment methods, our Common Entrance results can be used to ensure progress is made in the classroom. Our 2022 leavers achieved the following Common Entrance results:

Academic Scholarships

In addition to our published Common Entrance results, a number of children sit and are awarded academic scholarships each year. Our scholarship results can be viewed by clicking here.
