Why do smaller classes improve academic outcomes?
/
Smaller class sizes help improve children's overall school performance because they ...
- Facilitate more one-to-one time with the teacher
- Mean the quieter child does not get lost in the crowd
- Enable the teacher to manage discipline better
- Give space for the teacher to uncover strengths and weaknesses
- Permit a more supportive non-threatening learning arena
- Give more opportunities for children to contribute
- Mean teachers can differentiate beyond average ability
- Promote better collaborative social and communication skills
- Help shyer and less confident children feel more secure
- Enable children to get better quality in-person feedback
Some children come bounding into school ready to learn. Others are less eager and do just enough to get by.
Maybe you have a child who’s a consistent high achiever. But most children go through different phases. Perhaps you see something of your child in one of these descriptions?
Conscientious and high-achieving? Smart but distracted? Sensitive and perfectionist? Quiet and compliant? Lost somewhere in the middle? Able but uninspired? Convinced they’re not ‘academic’? Coasting and under-achieving? Struggling and discouraged? Disinterested and demotivated?
Small classes have most value at primary school stage
So how can a school cater best to all these different personality types, teaching approach requirements and developmental stages? Part of the answer lies in smaller class sizes.
Research by the Education Endowment Foundation shows that a class group of under 20 students gives the best results. It states that it is during the primary school years that children get the most benefit from being in a small class.
At primary school age, children are still yet to develop the independent learning skills and self-discipline that they’ll have by the time they’re ready for secondary school.
By the age of 11 or 12, pupils will be better equipped to thrive and learn in a bigger group environment. So is at the primary school stage that smaller classes provide the maximum learning boost.
This fact is backed by the Department for Education’s Class Size and Education in England Evidence Report which states: “The evidence base on the link between class size and attainment, taken as a whole, finds that a smaller class size has a positive impact on attainment and behaviour in the early years of school.”
Small classes are better for both less able and more able children
At Sompting Abbotts, class size is average 15 and we see better results. The more able children get the challenge they need. The 'coasters' are galvanised. The less able children – or those with SEND (special educational needs) – have more time with their teacher to receive the extra support they need.
Importantly, no child gets 'lost in the middle' or ‘forgotten in the crowd’.
Small classes enable the teacher to manage discipline better
In recent years, primary-school class sizes in the UK state sector have increased due to current funding cuts, putting additional pressure on teachers.
It is a tough ask for teachers to oversee a class of 30+ young children. It is difficult to do, even with the presence of a teaching assistant.
‘Managing’ is what you end up doing as a teacher when you’re confronted with a large class. Inevitably you have to gear your teaching to the middle ability to keep all children on task.
Small classes give space to uncover strengths and weaknesses
Spurts and dips are normal for children. They learn at different rates and it’s not always linear. Plateaus are not uncommon.
This could be because it is the way the child is developing right now. Or because other life issues are having an impact.
Teachers in a small class can judge this and respond in a measured way. This kind of stable support can be a big help when students are feeling overwhelmed by personal problems outside of school.
Small classes permit a more reassuring learning arena
In a small class, the teacher has space and time to uncover children’s strengths, weaknesses and personality traits.
They can create a learning environment that is supportive and non-threatening and, importantly, where mistakes are viewed as inevitable and useful. This is why behavioural problems in a small class are the exception rather than the rule.
More time with each child also means more time to listen to them properly: to hear their special news, answer questions and explain tricky concepts.
Small classes allow children to be stretched more carefully
According to the Department of Education, the UK has one of the largest average primary school class sizes of the OECD countries.
Hundreds of thousands of children are taught in classes of more than 30. This has been true for at least the last decade, although it’s become more common to have larger primary school classes recently – a fact that was underlined with the spacing issues that COVOD-19 imposed.
“Every child deserves to be stretched (carefully – they’re not pizza dough...). ”
In small classes, teachers can be nuanced beyond average ability
Teachers in smaller classes are less inclined to assume ability in their classroom follows a ‘bell-curved’ distribution. They don't plan on the basis that there'll always be roughly three groups of children: the below average, average and above average.
They can be more nuanced to fine-tune teaching to unlock children’s motivations to succeed. The best teachers are the ones who believe in the success of every student they encounter.
Because all children deserve to be stretched. Carefully – they're not pizza dough. So they can achieve their full potential – whether their strengths are academic, music, sports, drama or art.
“All teaching and learning takes place within a context, and one important feature of school classrooms is the number of pupils in a class. Smaller classes can help teachers provide a more effective education.”
Smaller classes at primary school stage allows greater individualisation.
But push aside the academics. School is also a social experience.
Collaborative learning activities in small groups promote positive social interaction.
Small classes promote better social and communication skills
Emotional and social skills will be just as important in life ahead for children as their eventual exam results.
We’ve noticed that small classes benefit the quieter and less-motivated child and the confident and outgoing child because they favour participation.
In a small class, there’s full incentive for pupils to pay attention and get involved because it’s obvious when they don’t.
Small classes help less confident children feel more secure
Often, the reason a quieter child doesn’t contribute is down to self-belief, not disinterest. In a large setting, when they feel insecure, they find it ‘scarey’ to put their hands up. So they let the self-assured ones hold sway.
But with the more relaxed atmosphere of a small class, a teacher can bring all children into group discussions.
For the confident child, the close collaboration of the smaller class also has benefits. They have to learn to be respectful – to listen, share ideas and be tolerant and patient.
These are useful skills. The World Economic Forum says the most in-demand future workplace skills will be these: critical thinking; problem-solving; collaboration; co-operation; adaptability; communication; initiative and curiosity.

“The gains from smaller class sizes are likely to come from the increased flexibility for organising learners and the quality and quantity of feedback the pupils receive.”
Small classes enable children to get better quality feedback
Do smaller classes lead to better outcomes? In our experience, they do. We believe that the foundation for children's future success are laid down during the crucial primary school years.
Giving children ‘the best start in life’ is a cliché (it features on a lot of school prospectuses!). But we are convinced that equipping children young is a longstanding gift.
There is truth in the saying: “Start children off on the way they should go, and even when they are old, they will not turn from it.”
Attention-challenged children focus more in smaller settings
Small classes at primary stage give best developmental value
We agree with Peter Blatchford, Professor of Psychology and Education at the UCL Institute of Education. He states: “Careful moment-by-moment systematic observation of pupils shows that class size affects the amount of individual attention pupils receive, and their engagement and active involvement in class.”
As the Education Endowment Foundation reports: “The gains from smaller class sizes are likely to come from the increased flexibility for organising learners and the quality and quantity of feedback the pupils receive.”
However, the real evidence comes for our staff from our own parents. "I can't believe how well you know my child," is something at parents evenings that we often hear them say.
And for us, that’s the greatest proof.
What's it like to be a pupil at Sompting Abbotts Preparatory School? Annabelle, Year 8, won the Ken Shearwood All Rounder Scholarship Award to Lancing College. She says that she benefitted from the small class sizes at Sompting Abbotts and her "inspiring and supportive" teachers.
“Intuitively, it seems obvious that reducing the number of pupils in a class will improve the quality of teaching and learning, for example by increasing the amount of high quality feedback or 1-1 attention learners receive. However, overall, the evidence does not show particularly large or clear effects until class size is reduced substantially to fewer than 20 or even 15 pupils. It appears to be very hard to achieve improvements from modest reductions in class size to numbers above 20, for example from 30 to 25. Overall the evidence does not show particularly large or clear effects, until class size is reduced substantially. The key issue appears to be whether the reduction is large enough to permit the teacher to change their teaching approach.”
