Wisconsin NAEP science results exceed national average

Wisconsin DPI, via a kind reader’s email:

cience scores for Wisconsin students exceeded the national average on the National Assessment of Educational Progress (NAEP) science assessment, administered between January and March of 2009.
The state’s scale scores on the assessments were 157 at both fourth and eighth grades, eight points higher than the national scale scores of 149 for both grades. In state-by-state comparisons, Wisconsin’s results at fourth grade were higher than those in 27 states, not significantly different from those in 12 states, and lower than seven states. At eighth grade, Wisconsin’s results were higher than 27 states, not significantly different than 14 states, and lower than five states.

Today I am releasing the 2009 National Assessment of Educational Progress science results.
Students were assessed at the fourth, eighth, and twelfth grades. Over 156,000 students at grade 4, 151,000 at grade 8, and 11,000 at grade 12 took the assessment. We have national results for public and private school students at all three grades. At grades 4 and 8, we also have results for public school students in 46 states and the Department of Defense schools. The state samples were combined and augmented with sampled students from the four non-participating states plus the District of Columbia, along with a national sample of private school students, to create the full national samples for grades 4 and 8. The twelfth-grade sample is smaller because there are no state-representative samples at that grade.
