Official Scottish government data published last month showed that 189 schools across Scotland were categorised as “poor” defined as “showing major defects and/or not operating adequately."

Another six were rated as “bad,” meaning they had come to the end of their “economic life” or were “at risk of failure.”

The number rated “bad” remains unchanged from 2024, and there has been a slight fall in schools rated “poor”  — down from 198 in 2024.

But more than 50,000 pupils continue to be educated in substandard buildings and the tally of schools assessed as “good” condition has fallen from 644 to 581 in a year.

The data, however, shows that there has been substantial progress over recent years, with 798 fewer schools rated in the bottom two categories than in 2007 while the number rated “good” or “satisfactory” climbed by 582.

Scottish Labour education spokesperson Pam Duncan-Glancy MSP said: “Young people are Scotland’s greatest asset, and we owe it to them to build an education system that allows them to reach their full potential.

“While there has been progress in improving the school estate, it is still unacceptable that nearly 200 school facilities across Scotland are not in an adequate condition for young people to learn.

“These figures demonstrate that there can be no room for complacency when it comes to investing in Scotland’s education system, ensuring that children have the best start in life.

“A Scottish Labour government will make Scotland’s schools world-class once again — from properly supporting teachers, to providing the resources pupils need to thrive.”

SNP George Adam MSP said: “Anas Sarwar’s claims don’t change the facts — the last time Labour were in power, they left Scotland’s schools in a terrible state.

“Under the SNP, 92 per cent of Scotland’s children are learning in schools rated good or satisfactory — the highest number ever, up from just 62.7 per cent when we took office.”
