The Unmistakable Difference: Educators Speak Out on Class Size Impact
For decades, the debate around class sizes in British schools has simmered, often dismissed by policymakers as an expensive luxury with minimal educational returns. However, a chorus of experienced teachers is now speaking with one voice, drawing from years in the classroom to challenge this assumption with compelling, first-hand evidence.
A Lockdown Revelation in Liverpool
Caroline Manley, a primary school teacher with twenty-five years of experience, describes the 2020-21 academic year as nothing short of revelatory. During the spring 2021 lockdown, her class in Liverpool was reduced to approximately eighteen children, comprising key workers' children and those with special educational needs and disabilities (SEND).
"For the first time ever," she writes, "I could sit with an individual child for five whole minutes to resolve a maths difficulty, or have an in-depth reading discussion." This unprecedented level of individual attention transformed the classroom dynamic. Science investigations that were previously logistical nightmares became feasible due to adequate space and resources.
Most strikingly, SEND children developed the confidence to voice opinions and seek help actively. Every pupil present was able to fulfil their academic potential in ways that seemed impossible under normal, crowded conditions. Manley describes this period as "a vision of what education could be." The return to full classes in March brought a stark contrast: children once again lacked elbow room to write properly and had to share vital resources between six.
Four Decades of Evidence from Hertfordshire
Carole Kendall, who spent forty-two years in primary education across various roles including class teaching, music specialism, and teacher training, offers a broad perspective. She has observed and taught classes ranging from a single pupil to the standard thirty-plus in state schools, noting that private institutions typically maintain numbers below twenty.
"It most definitely makes a difference to teaching and learning," Kendall asserts. "The outcomes are not the same." She identifies the core issue as financial, stating that small classes cost money, which remains the bottom line for many decision-makers. In her view, politicians and educational leaders are often reluctant to admit the superiority of smaller groups, despite the benefits massively outweighing the few disadvantages.
Historical Perspectives from Cumbria and Beyond
Professor Colin Richards, a former primary school teacher and schools inspector from Cumbria, casts his mind back to the late 1960s. He recalls the immense challenge of attempting to teach a class of forty-eight nine- and ten-year-olds single-handedly in a severely overcrowded classroom. He places the word "teach" in telling inverted commas, questioning how effective his instruction could possibly have been under such conditions.
He admits he couldn't know all the children well, with some regularly slipping his attention. The class included children with a range of special needs that he neither recognised at the time nor could have addressed alone. Sixty years on, he argues that class size remains critically important. He suggests that falling school rolls present an opportunity to better meet special and individual needs, giving every child the attention they deserve.
Adding a historical footnote, Martin Goodwin from Standish, Greater Manchester, shares a class photo from his final year at Grange Junior School in Bradford in 1961, which shows forty-three pupils. While this highlights some progress—the current average class size in England is reported as 26.6 pupils—the underlying message from educators is clear: there is still a long way to go.
The Core Argument: A Matter of Basic Dignity and Efficacy
These letters collectively dismantle the argument that class size is irrelevant. They frame it not merely as an educational policy issue, but as one of basic working conditions and human dignity. As Caroline Manley powerfully concludes, "Anyone who says class size makes no difference hasn't spent their working day squashed up against their colleagues and still be expected to work and behave at their best, as our children have to every day."
The testimonies underscore that smaller classes enable:
- Individualised attention and support, particularly for SEND pupils.
- The execution of practical, investigative learning activities.
- Increased student confidence and participation.
- A more manageable and effective workload for teachers.
While financial constraints are acknowledged, the educators' consensus is unequivocal: the investment in smaller class sizes yields profound and tangible benefits for teaching quality and student outcomes, making it a priority that the education system can ill afford to ignore.
