Here come a set of charts to illustrate how Kentucky's 2015 NAEP results line up.
Point 1. Kentucky fourth grade results were significantly better than national results for all students, students with disabilities, students with free or reduced-price meal eligibility, African American students, and Hispanic students, and in a statistical tie for white students without disabilities or f/r meal eligibility.
Point Three: Fourth grade results improved significantly from 2013 to 2015 for all students, student with disabilities, students with f/r meals eligibility, and white students without disabilities or meal eligibility. (African American results are shown with greater growth than any of the other groups, but that result was not statistically significant. The number of Kentucky African American students participating in NAEP is small enough that many comparisons over the years have fallen in that statistical uncertainty zone.)
Point 4: Eighth grade reading results did not show statistically significant change from 2013.
Point 6. Even the fourth grade progress should make us impatient for more rapid improvement in students readiness, and the eighth grade sluggishness is far from what we need to see.
Point 7. Those gaps mean student potential unfulfilled and a weaker future for all of us. We must especially build greater improvement for those groups of students.
