NAHT Cymru has responded to the latest Programme for International Student Assessment (PISA) results, warning that the findings underline the urgent need for long-term investment and support for schools across Wales.

The results show that Welsh students continue to face significant challenges in mathematics, reading and science, with performance remaining below OECD averages and below levels seen prior to the pandemic. Wales recorded average scores of 456 in mathematics and 459 in reading and 476 in science.

Commenting on the findings, NAHT national secretary, Dr Graham Gault, said: "These results will be disappointing for everyone who wants to see Welsh education thrive.

"However, they should not come as a surprise. School leaders have repeatedly warned that years of financial pressure, recruitment challenges, rising levels of additional need and the continuing impact of the pandemic have created significant barriers to improvement.

"It is important that these results are not seen as a reflection of the dedication or capability of learners, teachers and school leaders. Across Wales, education professionals work tirelessly every day for children and young people, often in extremely challenging circumstances.

"PISA provides a useful international benchmark, but it is only one measure of an education system. The response must be thoughtful and evidence-based rather than driven by quick fixes or headline-grabbing reforms.

"School leaders need greater investment in staffing, support services, professional development and resources if they are to deliver the ambitions set out for Welsh education. Raising standards requires sustained commitment and long-term planning, not constant policy change."

NAHT Cymru said the findings reinforce concerns about educational inequality and the growing pressures faced by schools supporting learners affected by poverty and poor wellbeing.

Dr Gault added: "If we are serious about improving outcomes, we must tackle the wider barriers to learning that many children face. Schools cannot do this alone. Government, local authorities and public services must work together to ensure every child has the support they need to succeed.

"Our members remain committed to delivering excellent education for all learners, but they need the resources, trust and support necessary to achieve that goal."
