Scotland's PISA Results: What They Mean for Your Child

Scotland’s PISA scores fell for most of two decades. In 2022, Scottish 15-year-olds recorded their lowest maths score up to that point — 471, statistically similar to the OECD average of 472 — and headlines called it a crisis. PISA 2025, published in September 2026, showed no significant change from 2022 in any of the three subjects. But what do PISA results actually mean for your child sitting in a classroom in Dundee or Edinburgh?

What PISA actually is

PISA — the Programme for International Student Assessment — is a standardised test run by the OECD every three years. It assesses 15-year-olds in three domains: maths, reading and science. Around 760,000 pupils in 91 countries and economies sat the 2025 test. In Scotland, 3,066 pupils in 115 schools and colleges took part.

The test is not like a National 5 exam. PISA does not test curriculum content. It tests whether pupils can apply knowledge to unfamiliar, real-world problems — interpreting a graph about population change, for example, or evaluating competing claims in a news article. The OECD sets a baseline average of roughly 500 (this shifts slightly each cycle). Countries are then ranked above or below that average.

Scotland’s trajectory: the numbers

Scotland’s best PISA scores came in the early cycles — 526 in reading in 2000 and 524 in maths in 2003 — and the long decline ran to 2022 before levelling off in 2025. Here are the headline scores:

Maths:

• 2003: 524
• 2006: 506
• 2009: 499
• 2012: 498
• 2015: 491
• 2018: 489
• 2022: 471
• 2025: 467

Reading:

• 2000: 526
• 2006: 499
• 2012: 506
• 2018: 504
• 2022: 493
• 2025: 488

Science:

• 2006: 515
• 2012: 513
• 2018: 490
• 2022: 483
• 2025: 491

The maths decline is the starkest — a drop of 35 points from 2006 to 2022. The OECD put the 15-point fall in the OECD-wide maths average between 2018 and 2022 at about three-quarters of a year of learning, so by its own yardstick Scotland’s fall is well over a year and a half. Reading held up better until 2022, when it dropped noticeably. Science fell from 2006 to 2022; the 2025 rise to 491 is not a statistically significant change, and none of the three subjects moved significantly between 2022 and 2025.

Why the scores have declined

There is no single explanation. Several factors overlap:

Curriculum for Excellence implementation. CfE was rolled out from 2010–2011. Its emphasis on breadth, skills and teacher autonomy came at the cost of some of the structured, content-heavy teaching that tends to produce strong PISA maths scores. This is not a criticism of CfE’s principles — it is an observation that PISA rewards certain types of mathematical problem-solving, and the shift in Scottish classroom practice may have moved away from those.

The pandemic. PISA 2022 tested pupils whose learning was disrupted by COVID-19 school closures. Scotland closed schools for longer than some comparable countries. Scores fell across most of the OECD in 2022 — the question is whether Scotland’s decline was steeper than it should have been, and the evidence suggests the pandemic accelerated an existing trend rather than creating one.

Assessment culture. Scotland removed national testing in the early CfE years and moved towards teacher professional judgement. PISA is a timed, high-pressure written test. Pupils who rarely sit that kind of assessment may perform less well on it — not because they know less, but because they are less practised in that format.

Teacher recruitment and workload. Scotland has faced persistent teacher shortages in maths and science. Fewer specialist teachers, particularly in the early secondary years, may be contributing to weaker foundations.

How Scotland compares to England

In PISA 2025 England scored 492 in maths (Scotland: 467), 497 in reading (Scotland: 488) and 516 in science (Scotland: 491). Scotland was significantly below England in all three, significantly above Wales in all three, and statistically similar to Northern Ireland. Against the OECD average, Scotland was above it in reading and science and similar to it in maths.

The gap is real but the context matters. England has invested heavily in maths teaching through programmes like the Maths Hubs and Shanghai-method mastery training. Scotland has not made the same targeted investment. England also retained high-stakes national testing (SATs, GCSEs) throughout, keeping pupils more familiar with the kind of timed assessment PISA uses.

What PISA does not measure

PISA tests a specific set of skills in a specific format. It does not measure:

• Creativity or critical thinking beyond the test format — Scotland’s curriculum places heavy emphasis on interdisciplinary projects, collaboration and expressive arts, none of which appear in PISA
• Wellbeing — PISA collects some wellbeing data through questionnaires, but the headline scores are purely academic
• Breadth of curriculum — Scottish pupils study all eight curriculum areas through the broad general education, to the end of S3; PISA only tests three
• Equity of access — Scotland provides free university tuition, free school meals for all P1–P5 pupils, and 1,140 hours of funded childcare; PISA scores do not capture these structural advantages
• Teacher–pupil relationships — Scottish schools generally report strong pastoral care and smaller class sizes than the OECD average

A country could score brilliantly on PISA while having miserable, stressed children in high-pressure exam factories. PISA measures one thing. It does not measure everything that matters.

The policy response

The Scottish Government has acknowledged the decline. Policy responses include:

• The Muir report (2022), which recommended replacing the SQA with a new body, Qualifications Scotland — it took over SQA’s functions on 1 February 2026 — and the Hayward Review (2023) on reforming qualifications and assessment
• Increased focus on numeracy and literacy in the BGE phase
• Investment in SNSA (Scottish National Standardised Assessments) as a diagnostic tool in P1, P4, P7 and S3
• A commitment to review how maths is taught in early secondary, including the possibility of more specialist maths teaching in S1–S3

PISA 2025, published on 8 September 2026, found the decline had stopped rather than reversed: no subject changed significantly from 2022, and maths is still significantly below every cycle from 2003 to 2018. PISA is a lagging indicator — it reflects the system pupils have been educated in for a decade, not changes made in the last year.

Should you be worried?

Mostly, no — with a caveat.

PISA is a system-level diagnostic. It tells the Scottish Government and Education Scotland that something needs attention at the policy level. It does not tell you that your child is falling behind, that their school is poor, or that their Highers will be worth less. No university, no employer and no admissions tutor looks at PISA tables when making decisions about individual young people.

The caveat: if your child is struggling with maths, PISA confirms what many parents already suspect — that maths teaching in Scottish schools has not been strong enough for long enough. That is worth acting on. Ask at parents’ evening about your child’s specific attainment in numeracy. If they are behind, ask what the school is doing about it and whether additional support is available. Do not wait for system-level reform to fix an individual problem.

For the broader picture, PISA is one measure among many. Scotland’s education system has genuine strengths — breadth of curriculum, late specialisation, strong pastoral care, free university access — that PISA does not capture. It also has genuine weaknesses in maths and science teaching that the results have made harder to ignore. Both of these things are true at the same time.

The scores should prompt action from policymakers, not panic from parents. Your child’s education is shaped far more by the quality of their teachers, the culture of their school and the support they get at home than by where Scotland sits on an international league table.
