Maths mastery is a teaching approach used in many English secondary schools that prioritises deep understanding of fewer topics over rapid coverage of many. Rather than moving the whole class on when some pupils grasp a concept, mastery spends longer on each idea, building secure understanding through carefully structured questions before introducing new content.
Where does maths mastery come from?
The approach is rooted in mathematics teaching in Singapore and Shanghai, countries that consistently achieve among the highest scores in international studies such as PISA and TIMSS. English schools began adopting it significantly from around 2014, when the DfE funded exchange programmes and the NCETM (National Centre for Excellence in the Teaching of Mathematics) established the Maths Hubs network — a set of regional hubs supporting schools in adopting "teaching for mastery."
The Mathematics Mastery programme (now delivered through Ark) has supported hundreds of English schools in implementing the approach, and the Education Endowment Foundation has evaluated it and found on average around three additional months of learning progress for pupils compared with conventional approaches.
What are the key principles of maths mastery?
Teaching for mastery rests on a small number of well-evidenced principles:
- High expectations for all: the mastery approach assumes that all pupils — not just those deemed "naturally gifted" — can reach a secure level of understanding if given enough time and the right support
- Depth before breadth: spending longer on each concept, making sure it is genuinely understood rather than superficially covered, before moving on
- Concrete-Pictorial-Abstract (CPA): introducing new ideas first with physical objects or manipulatives (concrete), then with visual representations (pictorial), then with symbolic notation (abstract) — a sequence borrowed directly from Singapore's curriculum
- Intelligent practice: carefully designed exercises where the questions vary in a structured way, so that practising one problem builds understanding of a pattern or principle rather than just repeating the same procedure
- Whole-class teaching: the class moves through the curriculum together, with pupils who have understood the core idea moved on to deeper problems ("going deeper") rather than entirely new topics, and those who need more time given additional support within the lesson
How is mastery different from how maths used to be taught?
The traditional approach in many English schools involved:
- Separating pupils into "sets" (ability groups) from a young age and teaching different content to each group
- Moving quickly through the curriculum and revisiting topics briefly if needed
- Extending the fastest pupils by moving them to the next topic sooner
A mastery approach differs in that:
| Traditional approach | Mastery approach |
|---|---|
| Fast pupils move to new topics | Fast pupils explore greater depth in the current topic |
| Lower sets cover less content | All pupils cover the same core curriculum |
| Early setting from Year 7 | Setting often delayed to Year 9, 10, or beyond |
| Procedures and methods emphasised | Conceptual understanding emphasised alongside procedures |
| Reassessment of topics is infrequent | Regular retrieval of prior content built into lessons |
Does mastery mean no ability setting at secondary school?
Not necessarily, but mastery-approach schools tend to delay setting later than traditional schools. Many start Year 7 with mixed-ability teaching and introduce some element of grouping in Years 8 or 9. Fully mixed-ability maths teaching throughout KS3 is a choice some schools make; it is not a required feature of mastery, but the philosophy of "all pupils can succeed" often leads schools in that direction.
If your child's school uses maths mastery and teaches in mixed-ability groups, this can feel unfamiliar — particularly if you are used to a system where a "top set" pupil received extension work. Under mastery, extension means harder problems on the same concept rather than different content. Some high-attaining pupils find this frustrating initially; the evidence suggests most benefit from it over time.
What does maths mastery look like in a Year 7 classroom?
In a mastery-influenced Year 7 lesson, you might observe:
- All pupils working on the same topic (e.g., fractions), but with some working on increasingly challenging problems involving the same concept
- The teacher spending time on number sense and arithmetic precision, even though the content might seem basic compared with what the pupil did in Year 6
- A "retrieval starter" at the beginning — a short quiz on previous content — before new material is introduced
- Teachers using precise mathematical vocabulary and expecting the same from pupils
- Little visible "copying from the board and completing the same question twenty times" — instead, variation in the questions asked
Is there research evidence that mastery works?
The Education Endowment Foundation (EEF) has evaluated the Mathematics Mastery programme in randomised controlled trials and found a modest positive effect — on average around three months of additional progress. The effect is strongest when teachers have received sustained professional development in the approach; schools that adopt the label without the underlying training see smaller benefits. The EEF rates the evidence as promising but notes that implementation quality matters significantly.
Frequently asked questions
Will my child be disadvantaged if they move from a mastery school to a non-mastery school?
Unlikely. The national curriculum content covered is the same in both approaches — what differs is the depth and sequence. A pupil from a mastery school who moves to a traditional school will have strong conceptual foundations in the topics covered, though they may initially encounter topics taught in a different order. Most pupils adjust within a half-term.
My child says they keep doing the same things in maths and not moving on — is that normal?
Under a mastery approach, it is normal for lessons to revisit topics more deeply rather than always introducing new ones. However, if your child consistently feels unchallenged over several months, that may signal that the school's version of "going deeper" is not stretching them sufficiently. Raise this at the next parents' evening and ask specifically what depth work the teacher is providing for pupils who have mastered the core idea.
Can mastery help a child who is struggling with maths?
Yes — this is one of the approach's primary intentions. Because the class does not race ahead and leave slower learners behind, pupils who need more time to understand a concept receive that time within the lesson (often through small-group support from a teaching assistant) rather than being placed in a lower set and given reduced content. Parents of pupils who have struggled with traditional approaches often report that mastery teaching is more accessible.
Does maths mastery apply to GCSE and A-Level?
The mastery approach is most fully implemented in Years 7 to 9, but the principles — particularly intelligent practice, retrieval, and depth before breadth — continue to inform good maths teaching at GCSE and A-Level. At GCSE, setting is more common, but the emphasis on conceptual understanding and precise reasoning remains relevant and benefits pupils in the more demanding Higher tier papers.
