A state-by-state look at the percentage of fourth-graders who scored at or above reading and math proficiency levels on the National Assessment of Educational Progress, NAEP, which is administered by the Education Department's National Center for Education Statistics. Proficiency levels in both subjects are shown for both 2009 and 2011, with reading scores in the first two columns and math scores in the next two.

Notes: DoDEA stands for Department of Defense Education Activity, which supervises schools on overseas military bases. Details may not sum to totals because of rounding. Some apparent differences between estimates may not be statistically significant.
