This session offers a practical and reflective learning experience for secondary school leaders and SEND practitioners. It explores how cognitive assessment can be used to better understand learners’ focus, memory, and thinking skills, and how this understanding can inform more effective, targeted interventions. Drawing on research evidence from King’s College London and Imperial College London, alongside real school implementation, the session supports participants to build confidence in interpreting cognitive data, avoid common pitfalls, and translate insight into meaningful classroom and support strategies that help students make genuine progress.
