NumAssess gives primary teachers a clear picture of where each pupil is against the NCETM Mastering Number milestones — with automatic support plan alerts, no spreadsheets needed.
Free 45-day trial·No credit card required·Used by UK primary teachers
Aligned to Ofsted's Coordinating Mathematical Success framework and the DfE's Mastering Number programme.
Trusted by teachers tracking pupil progress across England
Designed with teachers, built around the NCETM Mastering Number programme
Every assessment maps to the NCETM Mastering Number milestones. You always know precisely where each child is — not just a number, but what they can and cannot yet do.
When a pupil falls behind, NumAssess doesn't just flag it — it walks you through a structured support plan with suggested NCETM teaching approaches, review schedules and evidence tracking.
For every milestone, NumAssess provides specific teaching strategies aligned to Mastering Number. From ten-frames to number bonds — the guidance is right there when you need it.
Support plans, review evidence, progress data and whole-school reports are all stored and exportable. When Ofsted arrives, your evidence is already there.
“A resounding, positive shift in mathematics education has taken place in primary schools.”

NumAssess directly addresses the priorities set out in Ofsted's Coordinating Mathematical Success report (2023) and the DfE's Strong Foundations in the First Years of School (2024).
“There is a large gap between the lowest and highest achievers, and between disadvantaged and advantaged pupils... systems are needed to assess the success of practice, ensuring children have the knowledge and proficiency before moving on.”
“Leaders intend that pupils 'keep up, not catch up'. These approaches set out a better path to proficiency for pupils.”
— DfE, Strong Foundations in the First Years of School, 2024
“Some schools use summative assessments to reflect upon and evaluate the curriculum and its implementation.”

NumAssess has completely changed how I track maths progress. I can see at a glance who needs support and exactly what to do next — it used to take me hours of spreadsheet work.
NumAssess flagged that three of my pupils were falling behind in Composition before I had even noticed. The support plan it suggested made an immediate difference.
