When educating international special education teachers, teacher self-efficacy should be evaluated to better understand the effectiveness of training and the delivery of services to students with disabilities. Professionals in the field of disability services, from the United States, conducted a five-day seminar with special education teachers in Tahiti. Participants were self selected teachers from the islands of Tahiti. The purpose of this study was to evaluate the self-efficacy previous to and after the five-day seminar. Teachers self-efficacy was determined through self-reported surveys. Results proved that cross-cultural seminars are beneficial for increasing the self-efficacy, as well as the knowledge base of international teachers in Tahiti. In addition, findings add to a limited research base for education of international teachers as well as the data collected in French Polynesia.
