The DfE funded a 3 year programme delivered by YST using lead teachers with expertise to support school staff to develop their inclusive practice in PE and school sports for pupils with SEND. We collected data throughout the 3 years to identify what the programme delivered and what difference it made – to individuals’ practice, school approaches and pupils’ experiences. Monitoring data, survey responses and depth qualitative work were used to describe effective practice in CPD for the education workforce.
