This document summarizes the results of an online survey investigating the use of assessment materials in schools for pupils with Social, Emotional and Behavioural Difficulties. The survey received responses from 11 schools. It found that while schools widely use assessment, it is not often for specific behavioral issues. Schools commonly assess academic abilities but seem to lack knowledge and confidence in administering behavioral assessments. The author concludes that rigorous behavioral assessment could help schools defend academic progress for these students. They plan to conduct further research on behavioral assessments and disseminate information to help schools.
