ranging from mild to quite severe. Other disabilities include speech or language impairments, physical disabilities, cognitive disabilities, mild to severe medical and emotional disabilities, and injuries (National Research Council, 2004). Although states and districts vary in their criteria for diagnosing disabilities and in the specific policies through which they implement the IDEA requirements, it is clear that teachers face far different challenges than they did prior to IDEA and that many teachers are responsible for students with a wide range of disabilities. Overall, the work of teachers has become more and more complex as the nation pursues the goal of equal, and equally high-quality, education for all students.
