Devereux devoted herself to learning how to best serve her students. Between the years of 1910 and 1918, Devereux participated in several post graduate endeavors, including the study of psychiatry, psychoanalysis and speech therapy at colleges and universities in the Philadelphia area. She also took apprenticeship training in the areas of occupational therapy, woodworking and handicrafts. All her efforts focused on improving the education and experience of the students in her charge. In 1914 she began working for the Philadelphia Normal School in order to teach post graduate students in the country's first course on special education.
