In key stage 3, pupils have seven lessons of maths per fortnight. Children will be placed either in a top set or a mixed ability class. Pupils follow the national curriculum. Pupils will be assessed every half term and classes will be reviewed to ensure pupils are grouped appropriately according to their ability and performance. In the summer term all pupils in Key Stage 3 will sit the national numeracy tests. There are two papers for each year group, a procedural paper and a numerical reasoning paper.

In key stage 4, pupils have eight lessons of maths per fortnight. Pupils are set by ability according to levels achieved at the end of key stage 3 and ongoing assessments throughout key stage 4.  Pupils follow the specification for the new WJEC Linear examinations. Pupils can achieve two GCSEs by the end of year 11: one in Mathematics and one in Mathematics Numeracy. Pupils will either sit the Higher, Intermediate or Foundation tier in these exams.
