Why Does Class Size Matter?

Class size is one of the most important factors shaping how much support and attention students receive every day. Smaller classes help teachers connect with students and personalize their learning. This means kids get more support, lessons can be tailored to their needs, and everyone has a chance to participate.

Research shows that smaller classes often lead to higher academic achievement, especially in the early grades. The Tennessee STAR experiment found that students in classes of 13-17 performed significantly better in reading and math than peers in classes of 22-25. Even more compelling: those benefits lasted well beyond elementary school, with students from smaller classes more likely to graduate high school and earn more later in life.

In Washington Township, schools work to keep class sizes manageable so every student can get the attention and support they need. Across NJ, the average elementary class size is 18, putting us in the top 30% of states with the smallest class sizes. By comparison, states like Utah average 26 students per class in elementary classrooms. Smaller class sizes help create a learning environment where teachers can meet students’ individual needs and support their growth both academically and socially.

I’ll always advocate to keep class sizes manageable in our district – every student deserves to be seen, supported, and set up to succeed.
