Reciprocal subject mentoring and support by specialist teachers between schools provides a valuable opportunity for CPD. A cooperative model is effective in giving schools and colleges the opportunity to provide and receive school improvement support and access a professional learning community. Key stage 5 standards tend to remain in line with the national average, but too many students achieve fewer A level A*-C grades than their peers nationally and too few students progress to HE, including to the most competitive universities. Building on a previous DFE Strategic School Improvement Fund KS5 project, Norfolk County Council and Educate Norfolk continued and extended an adapted version of this work within Norwich, to also include FE and KS4 provision. The original project aimed to raise A level attainment, progress and results across Norfolk, with a simple model of utilising existing KS5 excellence to provide targeted school to school support. Lead teachers in a range of key stage 4 and 5 subjects participated in a co-operative model to share expertise and support across a group of schools and colleges.
