Assistive technology (AT) benefits many individuals with intellectual and developmental disabilities (IDD). The appropriate application of accommodation solutions, whether they involve the use of AT or not, can be a complex process involving a team of people with various backgrounds. This article describes an in-service AT training program that was developed for case managers (CMs) serving individuals with IDD. The article goes on to describe results of the course evaluations designed to measure participant knowledge, attitudes, and behaviors relating to the application of AT in developing accommodation solutions for individuals with IDD. Results indicate that CMs saw limited financial resources as a significant barrier to obtaining appropriate accommodations. However, CMs also felt better equipped to identify appropriate AT accommodation solutions and were more likely to apply AT solutions following completion of the training program.
