The profession of school social work began in 1906 but was not recognized in federal legislation for students with disabilities until nearly 70 years later. However, since 1906, school social workers have worked with students considered at-risk for academic failure, including students with disabilities. This article highlights the beginning of the visiting teacher movement, from 1906 through 1920, with a particular emphasis on the role of the visiting teacher within the context of working with students with developmental disabilities. Implications for school social work practitioners are discussed.
