About the Data

Description of the data source, numerator, denominator, survey questions, and other relevant details about the national estimate.

Data Source: 
National Assessment of Educational Progress
Changed Since the Healthy People 2020 Launch: 
Baseline (Year): 
33.9 (2009)
Target-Setting Method: 
10 percent improvement

Number of eighth graders scoring at the proficiency level or higher for grade level in the mathematics skills test administered by the National Assessment of Educational Progress


Number of eighth graders attending public or private schools

Comparable Healthy People 2010 Objective: 
Not applicable
Data Collection Frequency: 
Methodology Notes: 

    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 five mathematics content areas: number properties and operations, measurement, geometry, data analysis, statistics, probability, and algebra.

Caveats and Limitations: 
Students are eligible for the National School Lunch Program (either free or reduced priced lunch) if their family income is at or below 185% if the poverty level. Data for English Language Learner cannot be generalized to the total population of English language learners--some students are unable to take the test. Students are classified by the school as having a disability. Students may have an individualized education plan (IEP) or a 504 plan. Data for students with disabilities cannot be generalized to the total population of disabled students--some students are unable to take the test.
