 So, I think the toughest thing is when you visit, it's how do you view yourself? And some still view themselves as imparters of knowledge and not developers of a process or at least along both of those things. So the challenging thing is to, is that this framework, this rubric, immediately may call into question how I view myself as a teacher. And so whenever identity gets threatened, you know you have a roadblock. So there's some that just immediately take to it and it gives language to what they know that they should be doing or feel like they have been doing, many of them. There's others that are in the middle and then there's some that are really hesitant to do it. I mean, we're really muddling our way through this so if we seem fully polished then we're clearly not. We're just working through this the same way as I think any other group would. Our teachers made a three-year commitment to being in the program. So you've got teachers that were pretty committed if they're willing to give three years anyway. And then the other thing that is that for substantive change to really occur, it takes that kind of time because what we're seeing now is that the end of this second year, it begins to permeate and the ones that were already there are even more there and the ones that critical middle group that you'd want to get on really to really make the feel like the grant turn. Both of us at the end I think of the seminar I looked at each other and said, the second set of summer sessions said, I think we turned a corner here. I think we got a critical mass believing that what we're doing really makes sense but this is two years of doing it. You have them long enough, you develop trust, you make it safe for them to share, you give them lots of choice where they can volunteer and they can emerge as leaders, they can support each other. And I think we're seeing that this is a really fine, one of the best parts of being involved in this taught group is the teachers themselves. This is a fine group of teachers. They were strong teachers when they came in to begin with but I think that we made some good decisions to have the same group over a course of years and to try to be as purposeful as we can about developing a safe environment where they can learn from each other.
