Back in 2010 one of the major reasons we heard for adopting the Common Core State Standards was that the results from new Common Core-aligned tests would be comparable across states.

It’s now 2017, and as Chalkbeat points out, this is yet another promise from the education community that hasn’t been kept.

Kentucky, of course, uses its own, self-created Common Core-aligned Kentucky Performance Rating for Educational Progress (KPREP) tests, which don’t compare to tests used in any other state.

But, even for those states that joined one of the two Common Core test consortia and are nominally using the same tests, Chalkbeat’s article points out that no one is calling the results comparable.

It makes you wonder if the underlying education in each state is even close to comparable.

Which brings up another problem.

We normally could answer that question about cross-state education performance with results from the National Assessment of Educational Progress (NAEP). However, there was a change in the way this federal test was administered in 2017. Right now, we won’t see the 2017 NAEP results for several more months, at least. Even then, it is possible the 2017 results might have problems because of those changes in administration procedures. So, even the NAEP might not be useful to analyze the Common Core and cross-state education performance as of 2017.

In any event, right now, that Common Core promise about comparing cross-state testing remains unfulfilled. With seven years under its belt since enactment, that doesn’t speak well for Common Core.
