 And I think this is really where it has to be a state and local conversation on looking at the data. It has to start with looking at the data. I think about the line of Tip O'Neill in a very different context, but all politics is local. And I know it's shortages are just the same in understanding where are the shortages? Why is this happening? Where is it happening? Before you can have the sort of knowing how to address the issues, you need to know is there a special education shortage in my state? Is there high teacher turnover of math and science teachers in my state in high need areas? This is, it has to be a state directed conversation some too many times we find in education we go right for the intervention and don't sort of look at the root cause of the problem and know what the scope of it is. And I think of the work of Ellen Sherratt who was at AIR and now at National Board and she spoke about it, I think it's the perfect term that before you're going into this conversation it's looking at multiple data points but it's having a coherent dialogue and a common language for how you're talking about that because we all talk about teacher shortages we talk about teacher turnover but we first need to know and this is particularly important on the state level to know what are the terms we're talking about what are the specific issues that we're dealing with then we'll know how to address it so along those lines at the National Governors Association in advance of the 2018 election what we're working on developing is identifying what are those decision-making tools that governors can use to get to the root cause? Cause analysis, there's been some great work done I think about Minnesota with their teacher shortage predictor or the teacher in supply demand reports they made it very actionable and as well as Missouri and Arkansas with teacher shortage predictor tools so what kind of planning tools can be in place if we're going to break this cycle of teacher shortages and teacher turnover it's going to be because there's been planning ahead on the issue and setting that in motion.
