The Nation's Report Card™ informs the public about the academic achievement of elementary and secondary students in the United States. Report cards communicate the findings of the National Assessment of Educational Progress (NAEP), a continuing and nationally representative measure of achievement in various subjects over time. NAEP collects and reports information on student performance at the national, state, and local levels, making the assessment an integral part of our nation's evaluation of the condition and progress of education. This report shows the following: average scores in mathematics and reading in 2013; the percentage of students at or above the "Proficient" level; and score gains for the 11 states that volunteered in both the 2009 and 2013 assessments. National average scores from the 2013 NAEP did not change from 2009. Among the 11 volunteer pilot states that participated in both the 2009 and 2013 assessments, 4 made gains from 2009 in mathematics, and 2 made gains in reading.
