About this ranking

Students enrolled in public elementary and secondary schools in the fall divided by the full-time-equivalent number of public school teachers, from the NCES Digest of Education Statistics (Common Core of Data). The year is the fall of the school year (2022 means fall 2022, the 2022-23 school year).

This is not class size: teachers include those who do not lead a regular class, such as special education and specialist teachers. NCES publishes it for selected years only (2000, 2012 and 2017 onwards).

Every value in the ranking comes from the same publisher and the same period, so the states are compared on one definition. Equal values share a rank.
