James Horn points to some serious achievement gaps in Tennessee.
A recent news story in the Tennessean found that the most recent TN standardized test scores show remarkable disparities between affluent and poor school districts across the state:
Out of the subjects we analyzed, Algebra II saw the largest performance gap with a staggering 72-percentage-point spread. Williamson County Schools posted a 74% proficiency rate, while Humboldt City Schools came in at 2%. Geometry came in second for disparities with a 71-point spread between Williamson County Schools, which saw 76% proficiency, and 2% proficiency rate for Humboldt City Schools.
The city of Humboldt is shared by both Gibson and Madison Counties. Gibson County is ranked #33 in household income, and Madison County comes in at #45. Williamson County, on the other hand, is ranked #1 in household income.
Not only are income gaps between advantaged and disadvantaged school systems reflected in test scores, but the same gaps are found within districts when comparing scores of “economically disadvantaged” students with students who are “non-disadvantaged.”
