Well, at this point there is nothing from any official avenue (or at least any that I have seen) that Texas is moving to the district system. It is all speculation and rumors. We know there may be talks but no one has 'officially' acknowledged anything more than that (once again to my knowledge). Until there is official word some districts may not be willing to discuss the issue with their mentors/coaches.
Now, before you say that it is ridiculous that a district would behave that way I have vast evidence to the contrary on how the educational system in this state works; don't get me wrong, I love my state and teaching high school but we definitely have our flaws. For instance, six years ago we went through a major standards re-write that completely revamped all CTE (Career Technology Education) courses. Districts
knew that the re-writes were actively happening and going to be implemented within a very short timeframe yet the majority did little to nothing to prepare for the changes. They took (and many of them still do) a, 'we'll cross that bridge when we come to it', attitude.
I understand what you are saying but (and maybe this is just my shortsightedness

) it is difficult for me to plan for the future based on rumors of things that may or may not happen.
