The National Assessment of Educational Progress Data


NAEP is the “Nations’ Report Card” that monitors levels of achievement in math, reading, science, writing, history, geography and civics for representative national samples of students. NAEP began collecting data in the early 1970s in math, science and reading and has measured trends about every 4 years. Writing, history, geography and math have also been tested periodically. Testing samples vary by test, but can include 9, 13 and 17 year old students or 4th, 8th and 12th grade students. State samples were begun in 1990 for 4th and 8th grade reading and math is order to allow statistically valid comparison across participating states. In 2003, all states were mandated to test students and national sample sizes are now about 125,000 for each bi-annual test.

Research with this data has included estimating models that might explain different achievement levels and trends across states in reading and math in terms of the level and use of resources and the characteristics of the state-based standards and accountability system. The data is also used to estimate the location of at-risk students in the nation and their characteristics, and to compare differential trends in achievement for white and minority students, and advantaged and disadvantaged students.
