Which U.S. States Have the Highest and Lowest Student/Teacher Ratios?

The average public school student/teacher ratio in the United States is approximately 15 students to one teacher, according to Public School Review. Why is student/teacher ratio important? It’s believed that smaller classes allow teachers to spend more time focusing on the needs of individual students, reduce the amount of class time needed to deal with disruptions, improve working conditions for both teachers and staff, and overall contribute to a more comprehensive and meaningful learning environment. Small class sizes are especially important for early education, special education, and students from disadvantaged backgrounds. Smaller classroom sizes also correlate with higher teacher satisfaction! The team at AAAStateofPlay has created a guide to the average student/teacher ratio by state to highlight where classroom size reform may be needed and to provide insights into each state’s educational system to help parents, teachers, and caregivers make informed decisions:

• What Are the Benefits of Having a Smaller Class Size?

A few of the benefits of a lower student/teacher ratio include improved test scores, a lower dropout rate, and higher graduation rates. The Student Teacher Achievement Ratio study, conducted in Tennessee during the late 1980s, discovered that a large reduction in class size resulted in an increase in student achievement by “an amount equivalent to about 3 additional months of schooling four years later.”

According to the OECD, or the Organization for Economic Co-Operation and Development, “Overall, evidence on the effects of reduced class size on student performance is weak. Also, there is no consensus on what the best ratio of students to teachers should be at different students’ ages, but there is wide agreement that younger children need more time and interaction with teachers for a quality education, supporting a lower ratio of students per teacher in early education. There is also some evidence showing that smaller classes may benefit students from disadvantaged backgrounds. Research also indicates a positive association of smaller class size and higher teacher satisfaction.”

Additionally, smaller average classroom sizes around the world seem to have some correlation with academic achievement. For example, Norway’s average student/teacher ratio is 10.5 to 1 for elementary school and 10.2 to 1 for secondary school. Norway is renowned for the quality of education that it provides for its students. While there are many factors contributing to it, such as plenty of play and exercise opportunities, it is likely that a lower student/teacher ratio plays a valuable role.
