Small Class Size Benefits Essays

Approved April 2014

NCTE has long-established positions on class size for English language arts teachers. In 1960 it adopted a policy that secondary teachers of English should teach a maximum of 100 students per day, and that elementary teachers should have a comparable load. In 1971 it passed a resolution to inform local, state, and national administrators and policymakers about this policy. In 1983 and again in 1995 there were resolutions urging more attention to the issue of class size. And in 1999 NCTE issued a position statement on class size and teacher workload.

Today public schools employ 250,000 fewer people than before the recession of 2008–09, while enrollment has increased by 800,000, and class sizes in many schools are at record highs (Rich, 2013). Recent research tells us why this matters:

What Is Class Size?

In research on early elementary school students, small classes usually mean fewer than 20 students, while for high school students the definition of “small” classes is usually somewhat larger. There are similar variations in what constitutes small classes for college writing instruction. In addition to the ambiguity about how many students constitute a smaller class, researchers use different strategies for assigning a class-size number. It can mean the number of students enrolled in the course, the number of students completing the course, or the number of students completing major course assignments (Arias & Walker, 2004). Furthermore, there is a shifting relationship between class size and teacher workload. Reducing class size can, for example, increase teacher workload if the number of students per class is lowered but teachers are assigned one more class per day.

Academic Performance

Overall, research shows that students in smaller classes perform better in all subjects and on all assessments when compared to their peers in larger classes. In smaller classes students tend to be as much as one to two months ahead in content knowledge, and they score higher on standardized assessments. It is worth noting, however, that some studies analyze student assessment results in terms of individual student performance and others in terms of class-wide aggregated performance, which can obscure the differences in individual students’ performances.

These positive effects of small class sizes are strongest for elementary school students, and they become more powerful and enduring the longer students are in smaller classes. That is, students who have smaller classes in early elementary grades continue to benefit from this experience even if they are in larger classes in upper elementary or middle school (Bruhwiler & Blatchford, 2011; Chingos, 2013).

Despite the generally positive effects of smaller classes, the benefits are not consistent across all levels and populations. Small classes make the biggest difference for early elementary school students, while for many high school students smaller classes do not make a significant difference in academic performance. However, for minority and at-risk students as well as those who struggle with English literacy, smaller classes enhance academic performance. Class size also shapes the quality of writing instruction at all levels, including college, because smaller classes are essential for students to get sufficient feedback on multiple drafts. Not surprisingly, smaller writing classes increase retention at the college level (Blatchford et al., 2002; Horning, 2007).

Student Engagement

Academic performance is important, but it is not the only measure of student success. In the area of student engagement, findings consistently show the value of small classes. Students talk and participate more in smaller classes. They are much more likely to interact with the teacher rather than listen passively during class. Not surprisingly, students describe themselves as having better relationships with their teachers in smaller classes and evaluate both these classes and their teachers more positively than do their peers in larger classes. Students display less disruptive behavior in small classes, and teachers spend less time on discipline, leaving more time for instruction. Specifically, teachers in smaller classes can diagnose and track student learning and differentiate instruction in response to student needs. In smaller classes students spend less time off-task or disengaged from the work of the class, and they have greater access to technology. Research also suggests that smaller class sizes can help students develop greater ability to adapt to intellectual and educational challenges (Bedard & Kuhn, 2006; Dee & West, 2011; Fleming, Toutant, & Raptis, 2002).

Long-Term Success

The benefits of smaller classes extend beyond test scores and student engagement. In addition to the longer-term positive attributes of small class sizes in the early grades, benefits include continued academic and life success. Researchers have found that reducing class size can influence socioeconomic factors including earning potential, improved citizenship, and decreased crime and welfare dependence. The beneficial effects of being assigned to a small class also include an increased probability of attending college. This benefit is greatest for underrepresented and disadvantaged populations. While the increased probability for all students is 2.7%, it is 5.4% for African American students and 7.3% for students in the poorest third of US schools (Dynarsky, Hyman, & Schanzenbach, 2013; Krueger, 2003).

Teacher Retention

Teacher quality has, for some time, been recognized as the most important variable in the academic success of students. Recruiting and retaining effective teachers has become increasingly important as school districts impose mandates about student test scores and overall academic performance. Class size has an effect on the ability to retain effective teachers because those with large classes are more likely to seek other positions. Research indicates, however, that instead of rewarding effective teachers by decreasing their class size, administrators often increase the class sizes of the most effective teachers in order to ensure better student test scores (Barrett & Toma, 2013; Darling-Hammond, 2000; Guarino, Santibañez, & Daley, 2006).

The Cost Factor

One of the most common arguments against smaller class sizes is financial. School districts claim that they cannot afford to reduce the size of classes because it would be too expensive. However, it is also expensive when students leave public schools to attend private ones. Research shows that class size is a significant factor in parents’ decisions to send their children to private schools. Despite the enormous emphasis on test scores in public schools, parents report little interest in these scores when choosing a school. Instead, two of the top five reasons parents give for choosing a private school are “smaller class sizes” (48.9 %) and “more individual attention for my child” (39.3%). The other three reasons are better student discipline, better learning environment, and improved student safety, all of which are influenced by class size (Kelly & Scafidi, 2013).


Class size is a major factor in student learning. To be sure, it is one of several important factors, and more research is needed to determine how it interacts with phenomena such as teacher quality and context, but existing research should guide policy decisions in several ways.

  • Do not conflate class size and teacher workload.

Class size can refer to enrollment in or completion of a given class or program of study, and each of these has different implications for a teacher’s workload. If a large number of students enroll but do not complete a course, for example, the ratio of class size to workload will shift depending upon whether enrollment or completion is considered. Furthermore, requiring teachers to teach more classes with smaller numbers of students in each does not constitute a decrease in workload.

  • Recognize that the benefits of reduced class size are not uniform across all grades and populations.

Although more research is needed to understand the full effect of class size, existing research shows that younger students, at-risk students, and special-needs students receive greater benefit from small classes than other populations.

  • Consider the differential effects of class size across the disciplines.

Most research on class size does not distinguish among disciplines, so it is easy to assume that an increase or decrease in class size will have the same effect in every classroom. However, a class that assesses student learning with multiple choice tests may not receive as much benefit from a reduction in class size as a class that assesses student learning with written essays.

  • Use multiple measures to evaluate the effects of reducing class size.

Since class size interacts with several dimensions of learning that extend beyond what can be measured with a standardized test, it is important to use several different measures to determine the effects of making classes smaller.

This article was written by Adam Hatch - UC Berkeley graduate, son of a teacher, brother of a teacher, and a teacher himself. Adam started a unique English school in Taipei, Taiwan, where kids learn to research and write articles in English. The articles are published on the first ever English newspaper written by kids in Taiwan, called the Taipei Teen Tribune.

Let’s compare two classes. In terms of teacher ability, student levels, and student behavior, they are essentially identical. The only difference is that one class has 10 students and the other has 30. Which class would you want to teach? Which class is better for the students? The smaller one is the obvious answer, but do you know exactly why? Here are the 10 reasons why smaller class size is so important:

1. More one-on-one time.

In our 10-student class, it stands to reason that each student will have three times more individual face time with their teacher. This type of educating is critical, both for development of skills and for inspiring students. With more one-on-one time with their teacher, students are certain to have a greater sense that their teacher cares for them, and when students feel like someone they look up to cares about their work, they excel.

2. Students can’t hide.

In a 30-student class, it becomes much easier for the quiet kids, or the unmotivated kids, to hide in a clique of friends or the back of the class. With fewer students, the teacher is more capable of ensuring everyone participates and engages the material. This ensures students can’t fake it, thus must keep up, while teachers can prevent declining engagement and scores.

3. Easier to identify issues.

In large classes, teachers can struggle to identify where problems might be arising, and then because their time is so valuable, they further struggle to adequately address these issues. When a teacher has 30 essays to grade, they will spend less time on each one and potentially glaze over flaws in writing skills that could be fixed with minimal instruction. Within these kinds of spaces, where teachers are spending too little time watching for and addressing individual issues, students begin to slip through the cracks.

4. More cohesive class culture.

A smaller class will ultimately make a more cohesive unit than a larger one. A class of 30+ students allows for the formation of cliques even within the class, as well as ensures not all students need to engage each other - students can often stick to who they are comfortable with. However, in a smaller classroom setting, students will have the opportunity to interact with and form relationships with all of their classmates, ensuring that the class is more supportive of each other.

5. Teachers can form better relationships.

Related to the increased amount of individual time spent is the quality of relationships teachers are able to build with each student. In smaller classes, teachers better know the strengths, weaknesses, and needs of each pupil. With this increased level of attention, teachers can more successfully relate and instruct, thus becoming more than a simple instructor, but a genuine role model.

6. Students are more engaged.

When students have a strong relationship with their teacher and know they are responsible for their work and level of participation, they are bound to be more engaged with the curriculum. This has two roots: first, students are in an environment where engagement and quality work is simply expected of everyone - it becomes something of a cultural norm; second, when students have strong relationships with teachers - when they care what their teacher thinks of their performance - they are certain to produce better work.

7. Go faster.

Simply put, with a small group, teacher attention is more focused, students are more inclined to engage and be enthusiastic towards the material, and when this happens, work gets done faster. When work is done faster, classes can cover more ground, explore more topics, and more completely experience the curriculum and ideas presented. And when all the work is done? Now everyone has time for more fun in class, thus improving class culture and cohesion.

8. Much less chaotic.

In a 10-student class, there will simply be less noise - it’s a matter of physics. Furthermore, it will be easier to avoid letting the group get out of hand, and as mentioned in #3, it is vastly easier to identify issues as they arise, thus ensuring a tranquil learning environment. And with a peaceful class, all of the other benefits presented above are amplified.

9. It’s easier on the teachers.

The above reasons are a list of the pedagogical benefits of smaller class sizes, but in aggregate they make for better, more productive, and easier-to-manage environments for the teachers. When teachers are given the space to be productive in a positive and peaceful class, they are simply happier and better at their jobs. The “grind” becomes less of one, teachers last longer in the field, and there is ultimately a net benefit for the field of education when teachers are happier.

10. Research shows tremendous benefits to small classes.

Don’t just take our word for it - the vast majority of research shows that students perform better in all subjects, at all levels, in smaller classes. Furthermore, the research points to other benefits of smaller class sizes besides those listed here, including long-term performance benefits and greater teacher retention.

With so much evidence in favor of small class sizes, don’t we owe it to students and teachers to make sure education occurs in the more constructive environment that smaller classes allow for? For better academic results, happier teachers, and ultimately a more educated society, promoting smaller classes should be a priority for teachers, parents, districts, and government officials.
