This document discusses why TESTA (Transforming the Experience of Students Through Assessment) is important. It begins by noting that assessment and feedback are critical to student learning but there are challenges like an over-reliance on summative assessments and disconnected feedback. TESTA aims to address these issues by rebalancing assessments to include more formative work, creating better connections between assessments, and improving feedback practices. The document provides examples of successful formative assessment strategies used in different university programmes. Overall, TESTA seems to improve student perceptions of assessment and feedback as well as enhancing staff and student experiences of the curriculum.
