Teacher Salaries Around the Country

I recently found a Web site of teacher salaries by state, alongside other statistics. The Web site provides charts comparing teacher salaries to such things as median house price, median household income, and cents of benefit per dollar of salary, but expanding the data set a bit to include a representative standardized test result led to the following intriguing result:

The figure is sorted by math results, from lowest to highest, and the dotted red lines are trendlines for the respective measures. Notice that there appears to be a negative correlation between teachers' total compensation (as a percentage of median household income) and math scores.

All sorts of considerations arise. There is a positive correlation between a state's median household income and its students success on the math tests, and a (less significant) correlation between results and per-pupil spending. The obvious rebuttal to my chart, therefore, would be that as household income goes up (along with test scores), teachers earn less as a percentage thereof, thus creating that negative correlation. However, further examination shows that teacher compensation and NAEP math scores both go up with median household income, while the teacher compensation in absolute terms has almost no effect on test scores.

Put differently, wealthier populations see better results on the tests and pay their teachers better, but paying teachers more does not remedy demographic disadvantages. Not surprisingly, given all of this, Rhode Island is tenth highest in total teacher compensation and ninth highest in per-pupil spending, but thirty-sixth in NAEP math scores.
