Unfortunately, doing valid comparisons of Kentucky’s NAEP scores to those from other states isn’t so easy. For one thing, statistical sampling errors in NAEP turn many apparent “wins” into nothing more than ties. Other factors such as wildly different student demographics and the ever-present achievement gaps complicate state to state comparison of scores, as well. You can’t just compare overall “All Student” scores from the NAEP and get a valid idea about relative state education system performance. You have to break the data out and do more refined comparisons.
I have done that for the NAEP Grade 8 math results using the NAEP Data Explorer tool to generate maps that show states where white students scored statistically significantly higher, the same as, or statistically significantly lower than Kentucky on this math assessment series. The results are very disappointing.
