2. JACK O’CONNELL State Superintendent of Public Instruction 2 NAEP Design NAEP collects data from a sample of schools in each jurisdiction. In many schools, only a random sample of students in a given grade may be assessed. Samples are stratified by geographic location, ethnic mix, school size, and STAR scores. Parents may opt their students out of NAEP. Learning disabled and English learner students may be excluded from the assessment if NAEP does not offer the appropriate accommodation or if the student does not normally take state tests. The NAEP assessments are matrix tests: No student answers every question. Scores are only reported at the state and national level.

3. JACK O’CONNELL State Superintendent of Public Instruction 3 Interpreting NAEP Results Comparisons should be focused on specific sub-groups of interest. –Whole state population comparisons are problematic. –For example, English learners have substantial impacts on California results. NAEP scores contain variability due to sampling and measurement error. –Statistical tests must be conducted to determine if observed differences are larger than would occur simply by chance. Changes in populations over time can impact statewide trends. –For example, the change in the proportion of economically disadvantaged students between 2003 and 2005.

10. JACK O’CONNELL State Superintendent of Public Instruction 10 Notes on Comparing Performance Among States Because of sampling and measurement error in NAEP, small differences in scores may not be significantly different. –Therefore, a ranking of states by average scale score is inappropriate. Differences in population composition can greatly affect scores. Differences in exclusion rates for various groups can potentially confound results.

18. JACK O’CONNELL State Superintendent of Public Instruction 18 Summary California student’s NAEP scores in reading and mathematics parallel the national trend. Progress in reading is slower than in mathematics. Hispanic students that are not English learners have made the greatest gains on NAEP in recent years.
