Assessment Grids

Assessment 2021-2022

Key Stage 3

For students in Years 7 to 9, we use age-related expectations of student performance based on the GCSE 9-1 grading system. These grades show what the student would be expected to achieve at the end of Year 11, based on their current level of work.

The descriptors of the age-related expectations are displayed in each subject’s Assessment Grids, using a common five column format, which are shared with students in school and parents via the links below.    

Students are set challenging targets based on prior KS2 attainment scores and other data sources, such as CATS tests (completed in the first few weeks of Year 7) and Family Fischer Trust (FFT) Targets and Reading Age information. Where students do not have a prior KS2 attainment score (such as students who attended KS2 at an independent school or abroad) then the target can be generated using the teachers’ judgements of what would be an appropriate aspirational target.

The distribution of grades across the year group is expected to be in line with the percentages below, which are based on the school’s previous performance against National Standards. Some subject areas may be skewed due to option choices and rotational setting structures.

Key Stage 4

For students in Years 10 and 11, data is collected in the form of predicted grades based on GCSE 9-1 grades, against their challenging target grades generated from their prior KS2 scores. Students who join the school in Year 10 without KS2 prior attainment scores will sit CATS tests to generate meaningful target grades.

Key Stage 5

Student data is collected in the form of predicted grades based on A Level A*-E grades. Targets are based on previous Key Stage 4 performance.
