NAEP, also known as “The Nation’s Report Card,” is a program of the US Department of Education that provides information on state and national student achievement. It also provides information on how student achievement has changed over time. NAEP conducts state and large-district assessments in grades four and eight and national assessments in grades four, eight, and twelve. Results are based on a representative sample of students, and individual student or school results are not provided. In California, district-level results are available only for Fresno Unified School District (USD), Los Angeles USD, and San Diego USD.
