A new tool from the Education Trust allows quick state-to-state comparisons of 2015 National Assessment of Educational Progress (NAEP) scores and changes over time from 2003 to 2015.
Of course, as we have pointed out before, it’s essential when doing such comparisons to break the scores out by race, which the new tool allows, in order to reach accurate and credible conclusions.
Here are some interesting comparisons I worked up that compare Kentucky’s white and African-American students’ NAEP scores in math and reading over time to those for Arizona, a charter school-rich state.
(Note: On these graphs, higher performance plots in the upper right quadrant, the place where you find Arizona’s (AZ) dot.)
This first graph shows how Arizona’s white eighth-grade students posted a higher math score than Kentucky’s white eighth-graders in 2015 (about 297 versus Kentucky’s 281 score, as plotted along the vertical axis) and more improvement over time between 2003 and 2015 (about a 14-point improvement versus Kentucky’s 4-point gain, as plotted on the horizontal axis).
Overall, charter rich Arizona was both a “Higher Performing” and “Higher Improving” state, while Kentucky fell in what the Education Trust shows as the “Lower Performing – Lower Improving” quadrant.
Now, here is how both states’ African-American students did on NAEP Grade 8 math.
Once again, Kentucky falls in the “Lower Performing – Lower Improving” part of the graph while Arizona is classed as “Higher Performing – Higher Improving.”
Of course, Kentucky reportedly does better on NAEP reading. Click the “Read more” link to see if that reputation holds out for the Grade 8 NAEP Reading results for Kentucky versus Arizona.
