Most social work students receive only limited instruction about disabilities in their general coursework despite a growing need for trained social workers in this area. In this paper, we argue that coursework dedicated to the field of intellectual and developmental disabilities (I/DD) needs to be implemented as an essential component of a graduate-level social work education. This paper presents a complete syllabus for a graduate-level course (referred to here as "I/DD 101") dedicated solely to teaching about I/DD in social work practice. Course content explores the historical, societal, and environmental factors influencing how social workers interact with individuals with I/DD across their lifespan. This syllabus is structured as a template that can be customized for different purposes and contexts. Rather than being viewed as definitive or comprehensive, it is offered as a resource and starting point for education in this field.
