A Comparative analysis

Where your class stands — against comparable classes.

The same cognitive profile your pupils build at home, placed against a set of similar classes: same year group, similar size, same sector, comparable intake. Pick a scope — from your school to national — and read every gap.

§ Reading the analysis

What the Town scope says about your class.

How the comparison group is built — each scope keeps only classes of the same year group (Year 1), of similar size (± 25 %), in the same sector (state-funded), with a comparable intake. Data is aggregated and anonymised; a scope with fewer than 5 classes is hidden. No pupil-level personal data leaves the school. These comparisons are for pedagogical steering — they do not rank pupils, teachers or schools. UK GDPR compliant. Figures are simulated for demonstration.
