Steve is headteacher of Church Cowley St. James Primary School and in 2017 founded AssessProgress to facilitate Comparative Judgement sessions for a group of 14 schools in Oxfordshire. The award-winning project enabled the teachers to improve the quality of their pupils writing over time and also had a last long impact on improving the quality of their teaching. Steve worked closely with the publishers of a comparative judgement software solution to improve functionality and now uses the approach to reliability assess portfolios of children's work across schools with high validity and a complete lack of bias. Steve is now working with 30 schools using Comparative Judgement to drive improvement in teaching and pupil outcomes.
