Get the analysis done — without losing leadership time.
School leaders can spend hours cleaning data, building tables and trying to work out which patterns actually matter. Reality Behind the Data provides an independent second pair of eyes, turning the dataset into a concise evidence-led narrative you can use in department, SLT and governor conversations.

Send one anonymised assessment dataset and receive an independent, leadership-ready review of attainment, pupil-group gaps, key concerns and 5–7 priorities for action. Normally £149.

Reality Behind the Data is led by Olwyn McCollin, whose career has included mathematics leadership, senior leadership, KS3 attainment and intervention, high prior attainers, curriculum, assessment and staff development. That experience matters because school data is never just a spreadsheet: it sits alongside curriculum, teaching, intervention and the practical realities of leading a school.
