National Assessment of Educational Progress (NAEP)

The National Assessment of Educational Progress (NAEP) was developed in 1969 to measure student achievement nationally, and is the only nationally representative and continuing assessment of what America's students know and can do in various subject areas. Since 1983, ETS, on behalf of the National Center for Education Statistics (NCES), has developed content, analyzed data and reported results for NAEP, often referred to as "The Nation's Report Card." Assessments are conducted periodically in the arts, civics, economics, geography, mathematics, reading, science, U.S. history and writing.


ETS has assisted the NAEP program in introducing numerous psychometric and assessment design innovations over the years. Most recently, NAEP has transitioned from traditional paper-and-pencil to a digital format. This transition to digitally based assessments reflects a commitment by ETS to incorporate cutting-edge technologies into NAEP assessments.

NAEP Data Explorer (NDE)

Developed by ETS researchers, the NDE is a powerful statistical tool that encompasses many analytical functions such as sophisticated searching, data comparison and chart and table creation. The enhanced NDE makes it even easier to explore NAEP results. This interactive, user-friendly web tool lets users do the following:

  • Build custom statistical tables, animated graphics and state maps using NAEP data.
  • Explore decades of assessment results for various subjects, grades and jurisdictions.
  • View information about factors that may be related to student learning.

  •  NAEP-TIMSS Linking Study
    NAEP-TIMSS Linking Study
    The National Center for Education Statistics initiated this special study to link the NAEP scale to the Trends in International Mathematics and Science Study (TIMSS) scale so that states could compare the performance of their students with that of students in other countries. The study was conducted in 2011 with eighth-grade students in all 52 states/jurisdictions that participated in the NAEP mathematics and science assessments.
  • Graphic from The Nation’s Report Card: Vocabulary 2013.
    The Nation's Report Card: Vocabulary 2013
    This special report focuses on students' performance on vocabulary questions that were part of the NAEP 2013 reading assessment. Students were asked to demonstrate their understanding of words used in literary and informational texts to highlight the importance of vocabulary in reading comprehension.
  • Cover from The Nation’s Report Card: High School Transcript Study 2009.
    The Nation's Report Card: High School Transcript Study 2009
    This study analyzed transcripts from a representative sample of 37,700 public and private high school graduates nationwide to show what courses they were taking, how many credits they earned and their grade point averages. It also examined the relationship between course-taking patterns and student achievement, as measured by the NAEP assessments using a subsample of approximately 30,100 of the graduates who also took NAEP.
