Your analogy is great for golf, but doesn't apply to education. Golf and golf instructors don't face the reality of the political system which impacts schools, teachers and students. Of course, teacher quality is critical to the success to any educational reform movement. However, to ignore the impact that the teacher has on students just won't fly (excuse reference to your mode of transportation)in the local decision making process for sustainability.

Just providing data on teacher quality, using the pd and implemetation data is not enough in many communities. Impact data is also necessary in the form of student work (notebooks), performance tasks, and test data both criterion referenced. This data must be used in a variety of ways. Teacher feedback about their effectiveness in facilitating student understanding of the "big idea" of what they just taught is critical for continuous and long term improvement by both the teacher and the student. This data is also essential to build the case for sustainability.
