The 2022-2023 data shows Arizona had the highest ratio and Vermont had the lowest. In the US, there are an average of 15.4 students per public school teacher. How much individual attention a public school student receives from their teacher could depend, in part, on where they live. Using data from the National Center for Education Statistics, an agency within the Department of Education, Business Insider ranked all 50 states and the District of Columbia by the number of students per public school teacher. The data — which shows there are about 50 million students and 3.2 million teachers total in the US — covers students from pre-kindergarten to high school during the 2022-2023 school year.
