About the National Data
Baseline: 40.2 percent of 4th grade students attending public and private schools had mathematics skills that were at or above the proficient achievement level for their grade in 2017
Target: 43.1 percent
The proficient achievement level is one of three National Assessment of Educational Progress (NAEP) achievement levels: basic, proficient, and advanced. Minimum cut-off scores are established for each achievement level by a standard setting process. The proficient achievement level represents solid academic performance for the grade level assessed. The mathematics assessment was designed to measure students' knowledge of mathematics and their ability to apply that knowledge in problem-solving situations. The mathematics framework classifies assessment questions in two dimensions, content area and mathematical complexity, that are used to guide the assessment. Each question is designed to measure one of the following mathematics content areas: number properties and operations, measurement, geometry, data analysis, statistics, probability, and algebra.
