The purpose of this annotated bibliography is to summarize relevant research to update practitioners and professional development (PD) providers about designing effective and impactful professional development models. Few studies were found specific to transition professional development; therefore, this bibliography includes a wider review of PD models, limiting the review to studies illustrating the five essential features of PD within education. Given that PD is multifaceted, many of the PD interventions incorporate multiple elements. This paper summarizes four studies in the area of transition-focused education, followed by 14 studies of professional development across a range of educational practices.
