Students' sense of "belongingness" and their engagement in academic study have been identified as key contributors to student success. A short instrument that can identify changes over time in students' sense of belonging to their institution, their academic engagement and their self-confidence has been developed and used in conjunction with the "What Works? Student Retention and Success Change Programme" (supported by the Paul Hamlyn Foundation and the Higher Education Academy). This article outlines the instrument, its rationale (including its relationship with other survey instruments) and its technical characteristics, and presents analyses of the data. The practical utilisation of the survey is also discussed.
