Roughly 7 million students in the K-12 public school system—14 percent—are identified as students with disabilities. Of these, more than 62 percent spend a large majority of their day in general education classrooms. Given the numbers, it is clear that general education teachers should possess the tools necessary to help students with disabilities succeed. Teacher preparation programs can be a powerful and critical lever for ensuring this support; however, most teacher preparation programs do not center students with disabilities in their curriculum for general education teachers.
