Rigid assessment deadlines assume students experience predictable lives, yet contemporary cohorts juggle work, caring responsibilities, disability, health issues, and increasingly complex study patterns. In 2025, a flexible deadline window model was introduced in a large first-year Chemistry unit, allowing students to choose their submission time within a defined window. This presentation reports on a mixed-methods investigation combining (1) analysis of actual submission patterns across Semesters 1 and 2, (2) a Qualtrics survey exploring student perceptions of flexible deadlines, and (3) staff workload and administrative outcomes.
Findings indicate that flexible deadlines do not lead to widespread procrastination; instead, students self-regulate in diverse and predictable ways that align with personal commitments and preferred study rhythms. Students overwhelmingly report that flexible windows reduce stress, support wellbeing, and promote equitable access - particularly for those balancing employment, disability, or family responsibilities. Staff outcomes were also substantially improved, with marked reductions in extension applications, deferred assessments, and administrative processes relating to formal accessibility adjustments.
When paired with clear structures and academic integrity safeguards, flexible deadlines offer a Universal Design approach to assessment that benefits a broad cross-section of students while enhancing teaching efficiency. This presentation argues that flexible deadline windows represent a practical, scalable, and inclusive assessment innovation aligned with equity and learner-centred design.
