The right classroom assessments can empower educators by providing a clear picture of student, cohort and whole school learning and progress. The qualities that make an assessment include validity and reliability, alignment to the curriculum, and the quality of design. The Digital Assessment Library (DAL), launched by the Victorian Curriculum and Assessment Authority (VCAA) in 2020, includes a suite of assessments, distinguished by content that is of high quality, designed appropriately to meet the needs of the classroom and is aligned to the Victorian Curriculum F-10. The vision of the DAL is to support schools with selecting, administering, and analysing student achievement, and providing support to meaningfully interpret the results. We then provide support using the data to inform targeted and differentiated planning, teaching and reporting to improve student, class, cohort and whole school outcomes.
