Attainment at key stage 1 

Pupils are assessed throughout the key stage and the final teacher assessment is recorded at the end of the key stage. West Sussex moderates key stage 1 (KS1) teacher assessments in over 26% of Primary schools and 50% of their First and Infant schools each year. The national expectation is that the pupils will achieve the Expected Standard (EXS) or be working at Greater Depth (GDS) at the end of the key stage. The interim assessment criteria provided by the Standards and Testing Agency indicated that assessment should be based on 100% achievement and not a ‘best fit’ model. West Sussex applies this advice rigorously.
We aim to exceed national average by 2022.

March 2020 performance

Revised results for 2018/19 academic year for combined reading, writing and maths (taken from NOVA, as publicly available data is not available). The proportion of pupils at KS1 attaining the expected standard continues to rise, from 61.5% in 2018 to 62.9% in 2019 and has narrowed the gap with national average to 2.0% from 2.8% in 2018 and 7.5% in 2017.
Our 2020-21 milestone target is to be in line with national average currently 64.9%

A full range of continuous professional development (CPD) has been developed for this academic year to support schools to accelerate learning for pupils towards the national averages. Link Advisers in the autumn term will build a comprehensive structure of support for each school based on visits through the School Effectiveness Strategy or traded visits from a range of services specific to the schools need. In addition to this, targeted support has been identified for clusters of schools whose data suggests that specific intervention needs to take place.
