About this ranking

Average scale score of public school students in mathematics, grade 4 on the National Assessment of Educational Progress (NAEP, the Nation's Report Card), on a scale of 0 to 500, from the National Center for Education Statistics. The year is the year of the assessment, given from January to March.

NAEP tests a sample of students, so each score has a margin of error and a difference of a few points between states or years is often not statistically significant. States are tested every two years (2003 to 2019, then 2022 and 2024). The national value is for public schools only, the group NCES compares states with. Scores are on the same scale across years and states but cannot be compared with state test results.

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.
