At Dixons, the most important assessment data in our academies comes from formative assessment. Every day, we use specific and repetitive minute-by-minute formative assessment and other leading indicators to help shape students’ learning. However, for our Trust and academy leaders, analysing summative data, even though it is lagged, can also help to inform interventions and dynamic resource allocation both in the moment and over time. Teachers also use the information gathered from summative assessments to address gaps and support student learning.
