Earlier this year Wisconsin teachers and their supporters compared Wisconsin and Texas academically and claimed that Wisconsin had better achievement because it ranked higher on ACT/SAT scores. The fact that this claim ignored the ethnic composition of the states, prompted David Burge to use the National Assessment of Educational Progress(NAEP) to compare educational achievement within the same ethnic groups. His conclusion, based on the 2009 NAEP in Reading, Mathematics, and Science (3 subject areas times 2 grades, 4th and 8th, times 3 ethnicities, white, black, and hispanic equals 18 comparisons), was Longhorns 17 – Badgers 1.

The 2011 NAEP results are now available for Reading and
Mathematics. The updated conclusion (2 subject areas times 2 grades, 4th and 8th, times 3 ethnicities, white, black, and hispanic equals 12 comparisons) is Longhorns 12 – Badgers 0. Not only did Texas students outperform Wisconsin students in every one of the twelve ethnicity-controlled comparisons, but Texas students exceeded the national average in all 12 comparisons. Wisconsin students were above the average 3 times, below the average 8 times, and tied the average once.
Again, as in 2009, the achievement gaps were smaller in Texas than in Wisconsin.
