Education Week reports that testing for the Common Core State Standards isn’t going to be very “common” this year.

According to EdWeek, only 46 percent of the nation’s public school students live in states that will use one of the two Common Core testing consortia tests this year. Those tests, now mostly known by their initials as the PARCC and SBAC tests, won’t appear at all in many states like Kentucky that have chosen to develop their own, not-common, Common Core tests. Those non-PARCC/SBAC tests enroll 51 percent of the nation’s students.

Of note, a number of states, including Kentucky, were once a part of either PARCC or SBAC. In fact, Kentucky was an “observer” member of both consortia at one time but since abandoned its relationships, most recently with the PARCC effort.

So, states actually are leaving the SBAC/PARCC fold.

The non-PARCC/SBAC state-unique tests, though mostly supposedly developed around the Common Core State Standards, are different from each other. The results from state-unique testing cannot be compared to other states.

So, a big reason for adopting Common Core – common testing – seems to be coming apart, and the pace of that unravelling might even be accelerating.

Along the way, one of the major arguments for the Common Core State Standards appears to be waning on the vine. And, if Kentucky makes changes to Common Core after its standards review ends on April 30, 2015, we will become that much more uncommon, yet again.
