The document discusses the Students' Union Evaluation Initiative (SUEI), which is an assessment model that helps student unions improve their services and activities by identifying areas for growth. SUEI focuses on outcomes and impact, and asks students whether the union is making a positive impact on their lives. It provides benefits like improved governance and accountability for unions, and a way to measure performance for universities that fund student unions. The SUEI process involves cohorts of student unions working with consultants over multiple years to develop their evaluation practices.
