When we began the sustainability study, I believed that teachers at Socrates Middle School had developed a first-rate inclusion program and that structures—supportive leadership, collaborative culture, high-quality professional development, and shared decision making—were in place to sustain it. I had come to admire the SMS teachers and their commitment to students with disabilities, but seldom agreed completely with the decisions they made about the inclusion program. As a result, entering into the sustainability study, I was curious about the shapethe program had taken and whether SMS stakeholders retained their commitment to it. I felt less investment in the particulars of the program; I knew its flaws and understood that I would have little opportunity to contribute substantially to the process of improving it. Yet, in this regard, little had changed; it was the teachers who shaped and refined the original program, not RISES researchers.
