In a new academic paper published today, we study the extent that socio-economically disadvantaged children with top Key Stage 2 mathematics scores progress in this subject through school and into university. This is part of our Nuffield Foundation funded study into the outcomes of high-achieving disadvantaged children, with previous papers written on this topic available on this site.

Figure 1 illustrates how, of 31,310 disadvantaged pupils with top Key Stage 2 mathematics scores across two school cohorts, 19,160 (61%) achieved at least a GCSE B/5. By age 17 only 6,745 were recorded as studying mathematics, and just 5,000 took A‑level maths. From those A‑level takers, 2,770 obtained at least a B grade; around 1,105 went on to start a mathematics‑focused undergraduate degree; and roughly 715 achieved a 2:1 or first.

The mathematics pipeline is hence somewhat leaky – tens of thousands of disadvantaged children show clear mathematical ability at age eleven, yet only a tiny fraction go on to achieve at least a 2:1 in a mathematics-focused degree.

Two stages stand out as critical loss points. First, maintaining performance through to GCSE matters enormously: roughly 12,000 of the initial 31,000 high‑ability disadvantaged pupils do not reach a B/5 at GCSE. Second, subject choice at 16 is also decisive — about 14,000 more opt out of advanced mathematics after GCSE. A smaller, but still important, drop occurs when pupils choose university subjects. Taken together, these three losses explain why just 2% of disadvantaged pupils with high Key Stage 2 mathematics scores go on to obtain at least a 2:1 in a mathematics-based degree (physical sciences, mathematical sciences, computer sciences, engineering).

The distribution of losses from this pipeline is not uniform. Figure 2 presents differences in the probability of achieving a GCSE B/5 grade between high-achieving disadvantaged pupils of different ethnicities and genders. Estimates refer to percentage point differences compared with disadvantaged White boys.

The lost potential of disadvantaged White pupils is particularly acute. High‑achieving Asian pupils are, for example, around twenty percentage points more likely than equally high‑achieving White pupils to secure at least a B/5 grade at GCSE. Initially high-achieving disadvantaged Black pupils also outperform their White peers.

Yet, even when disadvantaged White pupils do continue to achieve a strong grade in GCSE mathematics, they are less likely to continue to choose to study this subject post-16. This is illustrated in Figure 3, which presents differences in the probability of taking A-Level mathematics amongst initially high-achieving disadvantaged pupils that achieved the same GCSE mathematics grades. Results are again presented compared to disadvantaged White boys as the reference group. Even when they are equipped to do so, White boys are around 16 percentage points less likely to choose to study A-Level mathematics than their Black and Asian peers.

Together, these results illustrate how many children show clear potential in mathematics at age eleven but fail to develop that early promise. If we want more home‑grown mathematicians, we need interventions that keep bright disadvantaged pupils engaged in mathematics at the moments that matter most. As we have highlighted previously, Key Stage 3 may be a key period when intervention is needed.

This includes during the GCSE to A-Level transition – when many young people who excel at this subject choose not to study it at an advanced level. Schools and colleges should support high‑ability disadvantaged pupils who excel at mathematics with targeted academic support, clearer subject‑choice guidance and stronger pastoral care that sustains their interest, motivation and aspiration in the subject.
