The Benefits of Smaller Class Sizes: A Research-Based Approach

The Benefits of Smaller Class Sizes: A Research-Based Approach

April 09, 2025

In an era of educational innovation and evolving pedagogical approaches, one factor consistently emerges as a significant influence on student success: class size. At Emmanuel Lutheran School in Asheville, North Carolina, we've long recognized the powerful impact of smaller class sizes on student achievement, teacher effectiveness, and overall educational quality. With class sizes ranging from 10-20 students, Emmanuel provides an environment where every child is known, valued, and appropriately challenged.

1. The Research Behind Smaller Class Sizes

Extensive research conducted over several decades provides compelling evidence for the benefits of smaller class sizes. The most well-known and comprehensive study, Tennessee's Student-Teacher Achievement Ratio (STAR) project, tracked students from kindergarten through third grade in classes of different sizes. The results were conclusive: students in smaller classes (13-17 students) significantly outperformed their peers in larger classes (22-25 students) in both reading and mathematics.

Subsequent research has reinforced these findings across grade levels and subjects. A meta-analysis published in the Review of Educational Research examined 77 studies and found that reducing class size had a significant positive effect on student achievement, with the most substantial benefits occurring when classes were reduced to fewer than 20 students.

What makes these findings particularly notable is their persistence across demographic groups. While all students benefit from smaller classes, research shows that the advantages are often most pronounced for traditionally underserved populations, including minority students and those from lower socioeconomic backgrounds. This aligns with Emmanuel Lutheran School's commitment to providing quality education to diverse families from throughout the Asheville area.

2. Measurable Academic Benefits

The academic advantages of smaller class sizes manifest in multiple ways that directly impact student learning outcomes:

Higher Achievement Across Subjects

Students in smaller classes consistently demonstrate stronger performance across the curriculum. At Emmanuel Lutheran School, where classes are capped at 20 students, teachers can provide the individualized instruction necessary for mastery in core subjects like mathematics, reading, science, and social studies.

This advantage extends to specialized subjects as well. In STEAM education (Science, Technology, Engineering, Arts, and Mathematics)—a cornerstone of Emmanuel's curriculum—smaller classes allow for the hands-on exploration, experimentation, and project-based learning that develop critical thinking and problem-solving skills.

Improved Reading and Mathematics Foundations

Early literacy and numeracy development benefit particularly from smaller class environments. Teachers can more effectively implement guided reading approaches, provide targeted phonics instruction, and ensure that foundational mathematical concepts are mastered before introducing more advanced material.

The benefits extend throughout elementary and middle school. As students progress to more complex reading comprehension, mathematical problem-solving, and critical analysis, smaller classes provide the necessary guidance and feedback for continued growth.

Enhanced Critical Thinking and Depth of Learning

Beyond simply covering material, smaller classes foster deeper understanding and application of knowledge. With fewer students to manage, teachers can design and facilitate more complex discussions, investigations, and projects that develop higher-order thinking skills.

At Emmanuel, smaller classes enable teachers to move beyond basic content knowledge to emphasis on analysis, evaluation, and creation—the upper tiers of Bloom's Taxonomy. This prepares students not just for standardized tests but for the complex thinking demanded in high school, college, and future careers.

Greater Academic Engagement

Student engagement—a critical factor in learning—increases dramatically in smaller classes. With fewer students competing for attention and participation opportunities, each child has more chances to contribute, ask questions, and receive feedback. This consistent engagement leads to stronger retention of material and more positive attitudes toward learning.

The statistics are compelling: studies show that student participation rates in smaller classes can be two to three times higher than in larger classes. At Emmanuel Lutheran School, this engagement extends beyond verbal participation to include hands-on activities, collaborative work, and independent investigation—all more effectively managed in smaller class settings.

3. Social and Emotional Development Benefits

The advantages of smaller class sizes extend well beyond academics to the crucial areas of social and emotional development:

Stronger Teacher-Student Relationships

Perhaps the most significant benefit of smaller classes is the depth of relationship possible between teachers and students. When teachers work with fewer students, they can truly know each child's personality, learning style, strengths, challenges, and interests. This knowledge allows for more personalized motivation, guidance, and support.

Emmanuel Lutheran School's teachers consistently cite these relationships as central to their effectiveness. When teachers can work with smaller groups, they can check in personally with every student every day, immediately noticing if someone is struggling academically or emotionally, and address issues before they become bigger problems.

Improved Classroom Management and Learning Environment

Smaller classes naturally reduce management challenges, allowing more time for actual teaching and learning. Research shows that teachers in smaller classes spend significantly less time on discipline and procedural matters—as much as 80% less in some studies. This translates to more instructional time and a more positive classroom atmosphere.

At Emmanuel, smaller classes enable teachers to establish clear expectations, consistent routines, and a supportive community. The result is a learning environment where students feel safe to take intellectual risks, participate actively, and develop their potential.

Greater Sense of Belonging and Community

Students in smaller classes report stronger feelings of belonging, importance, and community. Each child is more visible and has more opportunities to contribute meaningfully to class activities and discussions. This increased visibility helps students develop confidence and a positive academic identity.

Emmanuel's Christian environment enhances this sense of community, as students learn to see themselves and others as valuable members of God's family. Smaller classes facilitate the implementation of biblical principles of kindness, respect, and mutual support in daily interactions.

Enhanced Development of Social Skills

Contrary to what some might expect, smaller classes actually provide more opportunities for developing social skills. With teacher guidance and sufficient time for quality interactions, students learn to collaborate effectively, resolve conflicts peacefully, communicate clearly, and develop empathy.

In smaller classes, teachers can more closely monitor group dynamics and intervene constructively when needed. They can also ensure that all students have opportunities to work with different classmates, developing flexibility in social interactions that will serve them well throughout life.

4. Benefits for Teachers and Instructional Quality

While student benefits are paramount, smaller class sizes also significantly impact teacher effectiveness and satisfaction:

More Individualized Instruction

With fewer students, teachers can truly differentiate instruction according to learning styles, readiness levels, and interests. At Emmanuel Lutheran School, teachers regularly provide:

  • Extension activities for advanced learners
  • Additional support for students who need more time and guidance
  • Alternative approaches for different learning styles
  • Meaningful feedback on student work
  • One-on-one conferences to discuss progress and set goals

This individualization ensures that all students are appropriately challenged and supported in their learning journey.

Increased Active Learning Strategies

Smaller classes make it feasible to implement more active, engaging instructional strategies that might be unmanageable with larger groups. Emmanuel's teachers regularly incorporate:

  • Hands-on experiments and demonstrations
  • Interactive discussions and Socratic seminars
  • Collaborative problem-solving
  • Project-based learning
  • Educational games and simulations
  • Field experiences and community engagement

These approaches develop deeper understanding, stronger retention, and greater transfer of learning to new contexts.

More Thorough Assessment and Feedback

Assessment is most effective when it provides specific, timely feedback that guides future learning. Smaller classes allow teachers to evaluate student work more thoroughly and provide the detailed feedback necessary for improvement.

At Emmanuel, teachers conduct frequent formative assessments to monitor understanding and adjust instruction accordingly. They also provide substantive feedback on assignments, helping students understand not just what they did right or wrong, but how to improve. This process is significantly more manageable with 10-20 students than with 25-30 or more.

Reduced Teacher Burnout and Increased Satisfaction

Research consistently shows that class size significantly impacts teacher morale, job satisfaction, and retention. Teachers with smaller classes report greater sense of efficacy, less stress, and higher job satisfaction than those managing larger groups.

Emmanuel Lutheran School benefits from high teacher retention rates, with many faculty members serving for 10+ years. This stability allows for continued professional growth, strong teacher-parent relationships, and deep understanding of our curriculum and community.

5. Faith Integration and Character Development

At Emmanuel Lutheran School, one of the most significant benefits of smaller class sizes is the ability to integrate faith and character development more effectively throughout the educational experience:

Individual Spiritual Growth

In smaller classes, teachers can better know and support each student's spiritual journey. They can provide guidance, answer questions, and offer encouragement in age-appropriate ways. This individual attention helps students develop a personal understanding of faith rather than just general religious knowledge.

Emmanuel's teachers pray with and for their students, model Christian character, and help students connect biblical principles to their daily lives and academic subjects. These faith connections are more meaningful when teachers know their students well—something made possible by smaller class sizes.

Character Development Through Relationships

Character is formed largely through relationships and examples. In smaller classes, teachers can more effectively model and teach Christian virtues such as honesty, responsibility, kindness, and perseverance. They can also address character issues as they arise, helping students learn from mistakes and grow in virtue.

Emmanuel's approach to discipline emphasizes growth and restoration rather than merely punishment. This approach requires the time and relational foundation that smaller classes provide, as teachers work with students to understand problems, make amends, and develop better choices for the future.

Service Learning Opportunities

Smaller classes facilitate meaningful service learning projects that connect academic content with Christian values of service and compassion. At Emmanuel, these projects might include:

  • Creating care packages for those in need
  • Designing solutions to environmental challenges
  • Corresponding with elderly community members
  • Developing presentations on important social issues
  • Participating in community improvement efforts

These experiences help students see how their knowledge and skills can be used to serve others and honor God—a perspective that is more effectively developed with the guidance possible in smaller classes.

6. Practical Implementation at Emmanuel Lutheran School

Emmanuel Lutheran School's approach to class size isn't merely theoretical—it's implemented throughout our program from preschool through eighth grade:

Intentional Class Size Limits

Emmanuel maintains class sizes between 10-20 students, with capacity for each classroom set at 20 students maximum. This range allows for vibrant classroom communities while ensuring individual attention and engagement.

When classes approach maximum capacity, administration carefully considers the benefits of additional enrollment versus maintaining smaller class sizes. This thoughtful approach prioritizes educational quality and student experience.

Strategic Teacher Deployment and Support

To maximize the benefits of smaller classes, Emmanuel strategically deploys teaching resources:

  • Core classroom teachers focus on their primary students
  • Specialist teachers for art, music, physical education, and STEAM provide expertise in these areas while giving classroom teachers planning time
  • Resource support for students who need additional assistance
  • Teacher assistants in early grades to provide additional support

This staffing approach ensures that the benefits of smaller class sizes are fully realized through appropriate instructional support.

Classroom Design for Engagement

Emmanuel's classrooms are physically arranged to take advantage of smaller class sizes:

  • Flexible seating arrangements that can be reconfigured for different activities
  • Learning centers or stations for small group work
  • Adequate space for hands-on and project-based learning
  • Technology integration that supports personalized learning
  • Quiet spaces for independent work or small group collaboration

These physical arrangements would be far less effective with larger classes but enhance learning significantly with our 10-20 student groups.

Community-Building Emphasis

Smaller classes enable a strong emphasis on community building through:

  • Morning meetings that develop relationships and set positive tone
  • Class discussions where every voice can be heard
  • Collaborative projects that develop teamwork skills
  • Conflict resolution processes that restore relationships
  • Celebrations of individual and group achievements

These community-building practices are central to Emmanuel's educational approach and are facilitated by our smaller class sizes.

7. Addressing Common Questions About Smaller Classes

Parents and educators often have questions about the practical implications of smaller class sizes:

Does the benefit of smaller classes justify the higher tuition cost?

Research consistently shows that class size is one of the most significant factors affecting educational quality. While private education does involve financial investment, Emmanuel Lutheran School works to make this investment accessible through:

  • Competitive tuition rates compared to other private schools
  • NC Opportunity Scholarship eligibility for qualifying families
  • ESA+ program for students with special needs
  • School-based financial aid
  • Multi-child discounts

Many families find that the educational benefits, individual attention, and faith integration offered in Emmanuel's smaller classes provide tremendous value relative to the cost.

How do smaller classes prepare students for larger educational environments?

Some parents wonder if students from smaller classes will adjust well to larger high school or college environments. Research and our experience show that students from smaller classes actually develop stronger academic foundations, social skills, and confidence that serve them well in transitions to larger settings.

Emmanuel graduates regularly report that their experience in smaller classes helped them develop:

  • Self-advocacy skills for seeking help when needed
  • Strong study habits and time management
  • Confidence in participating and asking questions
  • Well-developed communication abilities
  • Adaptability and resilience

These qualities enable our alumni to navigate larger educational settings successfully, often taking leadership roles and maintaining academic excellence.

Are there any disadvantages to smaller classes?

While the benefits of smaller classes are well-documented, balanced consideration requires acknowledging potential limitations:

  • Less diversity of perspectives than might be found in larger groups
  • Fewer peers for social interaction and friendship formation
  • Potentially less competition in certain academic or extracurricular areas
  • More intense social dynamics when conflicts arise

Emmanuel addresses these potential limitations through:

  • Intentional community-building across grade levels
  • Mixed-grade activities and buddy programs
  • Collaborative projects with other schools and community organizations
  • Thoughtful guidance in navigating social relationships
  • Rich extracurricular offerings despite our smaller size

Our experience suggests that the benefits of smaller classes far outweigh these potential limitations, particularly when the school is intentional about addressing them.

What class size is ideal?

Research suggests that the most significant benefits occur when class sizes are reduced to fewer than 20 students, with diminishing returns below about 15 students. Emmanuel's policy of capping classes at 20 students aligns with this research while maintaining sufficient peer diversity for rich learning experiences.

The "ideal" class size may vary somewhat depending on:

  • Grade level (younger students typically benefit from even smaller groups)
  • Subject matter (some subjects may benefit from slightly larger discussion groups)
  • Teaching approach (project-based learning works well with 15-20 students)
  • Student characteristics (students with special needs may require smaller groups)

Emmanuel's approach provides flexibility within our overall commitment to smaller class sizes, allowing for optimal learning environments across our program.

8. The Asheville Context: Class Size in Local Schools

Understanding Emmanuel Lutheran School's approach to class size is enhanced by considering the local educational context:

Buncombe County Public Schools

Buncombe County public schools typically maintain class sizes of:

  • Kindergarten: 18-20 students
  • Grades 1-3: 20-24 students
  • Grades 4-8: 24-29 students

While these numbers reflect North Carolina's class size mandates for lower grades, they still exceed Emmanuel's maximum of 20 students per class. Additionally, public school classes occasionally exceed these targets due to budgetary constraints or teacher shortages.

Other Private Schools in Asheville

Private schools in the Asheville area vary in their approach to class size:

  • Some maintain similar caps to Emmanuel (around 20 students)
  • Others allow larger classes but emphasize additional teaching support
  • A few specialty schools offer even smaller classes at significantly higher tuition rates

Emmanuel's position within this spectrum represents a balanced approach that maximizes educational benefits while maintaining accessibility for a range of families.
