It’s been a day since the disappointing “Nation’s Report Card” results came out, and it has given me a chance to crunch some numbers a bit. They don’t tell us anything definitive – there is a lot more that impacts test scores than a policy or two – but it is worth seeing if there are any patterns that might bear further analysis, and it is important to explore emerging theories.
Not surprisingly, while many observers have been rightly hesitant to make grand pronouncements about what the scores mean, some theories revolving around the Common Core have come out. The one I’ve seen the most, coming from people such as U.S. Secretary of Education Arne Duncan and Karen Nussle of the Core-defending Collaborative for Student Success, is that the Core will bring great things, but transitioning to it is disruptive and we should expect to see short-term score drops as a result.
That is plausible, and we can test it a bit by looking at the performance of states (and the Department of Defense Education Activity) that have demonstrated some level of what I’ll call Core aversion. Those are states that (1) hadn’t adopted the Core at the time of the NAEP test; (2) had adopted but had moved away by testing time; and (3) were still using the Core at test time but officially plan to move away. They are broken down in the following table, which uses score changes in the charts found here:
