Does doing better in primary school show up in later pay?
DfE's own research links Key Stage 2 and GCSE results to LEO earnings records decades later — but every figure here is an association after statistical controls, not a proven cause, and the cohorts are people now in their 30s and 40s, not today's pupils.
A one-standard-deviation improvement in combined KS2 English and maths attainment is associated with £63,700 more in lifetime earnings in present-value terms (£157,500 undiscounted) — a 13.8% increase — after controlling for pupil characteristics and school attended.
Association, not causation
DfE's own words: "We caution against overly strong causal or deterministic interpretations of the findings in this report. They simply show the association between [attainment] and lifetime earnings, controlling for a range of other factors that could drive these outcomes." The department calls this a "selection-on-observables" approach — it adjusts for characteristics it can measure (free school meal eligibility, ethnicity, special educational needs, English as an additional language, local deprivation, and the school attended), not for everything that could jointly affect both attainment and earnings, such as the home learning environment or non-cognitive skills. Read every figure on this page as an association after those controls, not as a causal effect.

Maths and English attainment are associated with different-sized figures — not because one subject is inherently more valuable, but because that is what this specific regression finds after its controls.

Split by subject, a one-standard-deviation improvement in maths alone is associated with £42,200 more in present-value lifetime earnings; the same improvement in English alone, £26,500 more — maths carries a larger association than English.
Most of the maths association runs through GCSE results, not primary school alone
Once GCSE attainment is added as a control, the direct maths association falls from £42,200 to £9,600 present value (77% of it is explained by GCSE results), and the direct English association turns slightly negative — DfE's own reading is that most of the raw KS2 association operates through GCSE outcomes, not as a standalone primary-school effect.
By sex
Women: £75,200 present value (18% of average lifetime earnings). Men: £52,200 (10%). The percentage-of-earnings figure is larger for women, but the cash figure is larger for men, because average lifetime earnings themselves differ by sex.
By free school meal eligibility
Not FSM-eligible: £65,500 present value (13.7%). FSM-eligible: £52,400 (14.4%). The percentage return is similar across both groups — the cash return is smaller for disadvantaged pupils because their average lifetime earnings are lower to begin with.
GCSE attainment and lifetime earnings
A one-standard-deviation improvement in overall GCSE performance is associated with £96,000 more in present-value lifetime earnings — about 20% of average lifetime earnings — for pupils who sat GCSEs in the early 2000s.

Returns are largest at the D→C and C→B grade boundaries in most subjects; returns to top grades (A/A*) are robust in some subjects and not statistically distinguishable from zero in others. Non-FSM pupils show a 9% larger marginal return per grade than FSM-eligible pupils; men show an 18% larger average marginal return than women.
A different way of measuring the same question
Tracked only to age 25–33 rather than over a full simulated lifetime, a one-standard-deviation improvement in combined KS2 attainment is associated with 24% higher earnings and a 2 percentage-point higher chance of being in employment at 33.
Once highest qualification held is added as a control, the English earnings effect becomes statistically insignificant while the maths effect remains significant. DfE's own reading: "suggesting returns are generated through facilitating further higher-level study [for English]. Whilst in maths, estimates remain significant, suggesting the skills acquired hold intrinsic value in the labour market."
Ten years after GCSE, by post-16 route
This comparison is not adjusted for who takes each route
DfE's own words on this specific release: "These results should NOT be considered to show the causal impact of studying at a particular qualification level" and "Differences in outcomes between groups should not be attributed solely to obtaining qualifications." Unlike the KS2 and GCSE reports above, these are raw group comparisons, not adjusted for pupil characteristics — a weaker evidentiary standard, carried here rather than smoothed over.
Among the GCSE 2012/13 cohort, tracked to the 2023-24 tax year (~10–11 years after GCSE), non-graduate median earnings at ten years ranged £18,300–£25,600 for women and £24,500–£34,000 for men, depending on GCSE attainment quintile. DfE's own headline: "Apprenticeships (at level 4/5) offer the highest returns at this age" — among the pathways this release compares at the 10-year mark.
The proportion in sustained employment or further study at ten years after GCSEs is consistently higher for graduates than for those with no higher-level qualification, across the combinations DfE reports.
What this does not show
Whether raising a child's KS2 or GCSE grades would raise their future earnings
DfE's own words: "We caution against overly strong causal or deterministic interpretations of the findings in this report. They simply show the association between [attainment] and lifetime earnings, controlling for a range of other factors that could drive these outcomes." The department calls this a "selection-on-observables" approach — it adjusts for characteristics it can measure (free school meal eligibility, ethnicity, special educational needs, English as an additional language, local deprivation, and the school attended), not for everything that could jointly affect both attainment and earnings, such as the home learning environment or non-cognitive skills. Read every figure on this page as an association after those controls, not as a causal effect.
What this means for a child sitting these exams today
These are historical cohorts, not today's pupils. The KS2 study follows children who sat their Key Stage 2 tests between 1996/97 and 1999/00 — people now in their late 30s. The GCSE study follows pupils who sat GCSEs between 2001/02 and 2004/05 — people now in their late 30s. Both DfE reports note the roughly 20-year gap between the cohort and today when interpreting the results: curricula, qualifications and the labour market have all changed since, so these are records of what happened to specific people, not predictions for a child taking these exams now.
A complete picture of income
LEO links school records to HMRC and DWP data, not a survey — but it only captures earnings reported through PAYE (from 2003/04) and self-employment tax returns (from 2013/14). DfE's own words: "They do not contain information on dividends or other forms of capital income." People who move abroad, or whose income sits below the reporting threshold, are typically excluded from earnings figures rather than counted as zero — a real coverage gap this page cannot correct for. For cohorts observed only into their 30s, DfE simulates the remaining working-life earnings using Labour Force Survey transition data rather than observing them directly, which is a modelled projection, not a recorded fact, for every year beyond the last observed one.
