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

Scotland’s PISA scores have fallen. In 2022, Scottish 15-year-olds scored below the OECD average in maths for the first time. Headlines called it a crisis. 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 690,000 students in 81 countries sat the 2022 test. In Scotland, approximately 3,200 pupils across 108 schools were sampled.

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 PISA performance peaked in 2006–2012 and has declined since. Here are the headline scores:

Maths:

• 2006: 506
• 2009: 499
• 2012: 498
• 2015: 491
• 2018: 489
• 2022: 471

Reading:

• 2006: 499
• 2012: 506
• 2018: 504
• 2022: 493

Science:

• 2006: 515
• 2012: 513
• 2018: 490
• 2022: 484

The maths decline is the starkest — a drop of 35 points from 2006 to 2022, equivalent to roughly a year of schooling by the OECD’s own rule of thumb. Reading held up better until 2022, when it dropped noticeably. Science has been falling steadily since 2006.

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. Every country saw declines 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

England also declined in PISA 2022, but less sharply. England scored 489 in maths (Scotland: 471), 494 in reading (Scotland: 493), and 503 in science (Scotland: 484). England remained above the OECD average in all three domains; Scotland dropped below in maths and sat around the average in the other two.

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 until S4; 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 Hayward Review (2023), which recommended replacing the SQA with Qualifications Scotland and reforming 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

Whether these measures will shift the next PISA results (expected from the 2025 cycle, published in late 2026) remains to be seen. 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.
