Spotlight on the States provides achievement results for public school students in the nation and participating states. This chart contains achievement level data for 40 states, the District of Columbia, Guam, and Department of Defense schools, both overseas (DoDDS) and domestic (DDESS). Not all states appear because some elected not to participate in NAEP, and others failed to satisfy all criteria (*).
