Fieldwork is an integral phase of occupational therapy education, bolstered by a small but growing evidence base. A broad understanding of the state of that evidence base is necessary to inform the directions for future growth. The purpose of this work was to establish the current state of occupational therapy fieldwork literature, map that literature to recognized criteria for educational research, and identify gaps in the existing literature. Authors followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines to conduct a mapping review of articles with a primary focus on fieldwork education of occupational therapy (OT) or occupational therapy assistant (OTA) students in United States (Accreditation for Occupational Therapy Education)-based programs. Mapping criteria included level of education [OT, OTA], level of fieldwork [Level I, Level II], and categories of the AOTA "Education Research Agenda -- Revised" (2018). Sources included four databases (Academic Search Premier, CINAHL, ERIC, PubMed) and one additional journal (Journal of Occupational Therapy Education). A total of 1,619 articles were identified, with 67 articles meeting inclusion criteria. The 67 included articles disproportionately focused on Level II OT fieldwork (53%, n=36), with sparse representation of Level I OTA fieldwork (1.5%, n=1), and addressed only two categories of the Education Research Agenda (2018; 80%, n=54). Level I fieldwork, occupational therapy assistant programs, and large swaths of the association's Education Research Agenda (2018) were dramatically (or completely) underrepresented in fieldwork education research, suggesting important priorities for the immediate future of occupational therapy fieldwork education.
