California NAEP Results

National Assessment Educational Progress Reports for California.
Introduction

The results of the National Assessment of Educational Progress (NAEP) are reported between six to 18 months after they have been collected. The No Child Left Behind Act mandates reporting of State NAEP Mathematics and Reading Results within six months of the last day of the assessment period. Results for the Trial Urban District Assessment (TUDA) assessments in subjects other than mathematics and reading are usually available within one year of the assessment.

Accessing NAEP Reports

NAEP Reports may be accessed at the Nation's Report Card website External link opens in new window or tab.. For State and TUDA NAEP assessments results, a one-page Snapshot Report is generated for each subject and grade assessed. Links to the most recent California and TUDA Snapshot Reports for the NAEP are provided below.

Interpreting NAEP Results

It is important to keep in mind the following points when interpreting NAEP data.

  • The averages and percentages presented are estimates based on samples of students rather than on entire populations.
  • The questions students respond to are only a sample of the knowledge and skills covered by the NAEP frameworks.
  • Results are subject to uncertainty, reflected in the standard error of the estimates – a range of from less than one point, to over 18 points for smaller sub-groups.
  • Differences between scores or between percentages are discussed only when they are significant from a statistical perspective. Some seemingly large differences may not be statistically significant.
  • It is important to note that simple cross-tabulations of a variable with measures of educational achievement, like the ones presented in this report, cannot constitute proof that a difference in the variable causes differences in educational achievement.
  • The California Assessment of Student Performance and Progress (CAASPP) system is based on a different set of standards than the NAEP assessments. For example, the CAASPP assesses English language arts/literacy, encompassing reading, writing, listening, and research/inquiry; while the NAEP assesses reading.
  • Scores on the CAASPP and other assessments are not directly comparable to those on NAEP.
  • Achievement levels for California statewide tests and NAEP are not equivalent. Comparisons involving statistics such as percent proficient should be made with extreme caution.
