“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. The Nation’s Report Card compares performance among states, urban districts, public and private schools, and student demographic groups.”
The Nation’s Report Card: Economics 2006: “This report presents results of the first ever National Assessment of Educational Progress (NAEP) U.S. economics assessment in 2006.

The overall national average score was set at 150.”
