Each NAEP assessment is based on an organizing framework, similar to a blueprint, that is developed by education and assessment experts. Frameworks provide information about the content to be assessed in each subject and what knowledge and skills are appropriate for students being assessed in those subjects. The frameworks also offer insights about how to measure skills and student achievement in innovative ways.Learn More

NCES conducts secondary analyses of NAEP results. These studies focus on unique populations of students, including students of different racial/ethnic groups, ages, grades, and those in different types of schools and geographic regions. To gain a clearer picture of these unique populations, secondary analyses may involve additional data collection. NCES also conducts a number of special NAEP studies that involve the evaluation of technical procedures, statistical models for comparison-based analyses, and other methodologies.
