Ask parents and they will practically certainly say that they would choose their child to go to a school that has smaller class sizes. Intuitively, it makes sense: smaller classes equal much more personal attention, which equals much more learning.
But does it actually make much difference? As education budgets are tight, the potential costs vs the potential gains should be weighed up. So, what impact, if any, do small class sizes have?

The benefits of smaller class Sizes
Improvements in academic Achievement
One of the most well-known studies that investigated class sizes compared lessons in a small class (13-17 students) with those in a regular sized class (22-26 students) over a four-year period. The researchers found that students who were in the smaller class made much more improvement than their peers in the regular class. This impact was worth an additional 3 months Camiseta Bayern Munich of schooling, with this effect being even larger amongst minority students. Therefore, it seems Camiseta Gremio that smaller class sizes have the potential to enhance academic achievement.
Greater teacher Retention
A recent survey conducted by TES found that workload drove 81% of teachers to consider quitting, whilst a third of teachers argued that their workload had never once been manageable during the last year.
Marking is one of the most significant elements in this; it for that reason is logical that if there were fewer students’ work to mark, there would be a reduction in workload and as such improve teacher retention rates.
Better Staff-Student Interaction
Research has demonstrated that smaller class sizes give teachers much more time to get to know each of their students on a personal level, allowing them to better understand what students need them to do to help enhance their learning.
This interaction also improves the relationship between the teacher and their student, which subsequently increases the respect students have. In turn, they are much more engaged in lessons and much more likely to ask for support ought to they need it.
It’s Not All That Straightforward
No relationship between class size and PISA
PISA is a global international measure of how well each country is doing in education. research has shown there to be no relationship between class size and a country’s PISA score.
East Asian countries consistently have very high PISA scores and often have the largest classroom size. For example, they have larger classroom sizes but instruct fewer lessons per week (720 minutes on average per week, in comparison to an average around 1200 per week in the Western world). This implies that they have much more time available for preparation and marking, enhancing the quality of both.
Lack of value for Money
Research from the Camiseta Selección de fútbol de Países Bajos education Endowment foundation found that for class sizes to have an impact on student’s progression, the reduction needs to be down to 15-20 students. The cost of doing this (in terms of additional teacher salary and building new classrooms) would suggest that, pound for pound, this is one of the least affordable interventions a school can implement.
Final thought
Reducing classroom sizes has numerous potential benefits. These include better grades, better teacher well-being and better communication within the class.
However, what is good in theory isn’t always the same in practice. The sheer cost of decreasing classroom sizes to make a meaningful difference makes it a lot less feasible. With budgets being so tight, other interventions offer better bang for your buck.
