A study, entitled "The Mirage," was based on surveys of 10,000 teachers and 500 school leaders, along with interviews with more than 100 staff involved in teacher development. The surveys and interviews were conducted in three large school districts and a mid-sized charter school network.
PD costs were found to average $18,000 per student per year. Based on findings, it is estimated that the 50 largest U.S. school districts alone spend about $8 billion annually on teacher development, far more than was previously thought.

"The Mirage" study describes the widely held perception among education leaders that we already know how to help teachers improve, and that we could achieve our goal of great teaching in far more classrooms if we just applied what we know more widely. Our research suggests that despite enormous and admirable investments of time and money, we are much further from that goal than has been acknowledged, and the evidence base for what actually helps teachers improve is very thin.
Great teaching is very real, as are teachers who improve over time, sometimes dramatically so. Undoubtedly, there are development experiences that support that improvement. But we found no clear patterns in these success stories and no evidence that they were the result of deliberate, systemic efforts. Teacher development appears to be a highly individualized process, one that has been dramatically oversimplified. The absence of common threads challenges us to confront the true nature of the problem—that as much as we wish we knew how to help all teachers improve, we do not.
1 .. REDEFINE what it means to help teachers improve and Define “development” clearly, as observable, measurable progress toward an ambitious standard for teaching and student learning.
3 .. REEVALUATE existing professional learning supports and programs
New Zealand currently requires PD programs to produce academic gains in students by measuring the effect sizes produced by PD. It is all about improving student learning.

There was NO ... observable, measurable progress toward an ambitious standard for teaching and student learning due to this fall 2007 adoption of EDM materials and accompanying professional development.
It is way past time to REEVALUATE existing professional learning supports and programs.
It would also be a good idea to use relevant data in the selection of textbooks and materials.
