Purpose: The purpose of this paper is to serve as a comprehensive review of short-term study abroad (STSA) outcomes to help guide future STSA and study abroad (SA) scholars and practitioners in the further development of the field. Design/methodology/approach: This paper is the first comprehensive and systematic review of all outcomes of STSA programs within the SA body of research based on 156 papers. Findings: The study provides the first comprehensive classification of all previously studied STSA outcomes (85) into six categories: cross-cultural outcomes, STSA pedagogy outcomes, personal and professional outcomes; language outcomes; teacher and faculty outcomes; and other outcomes. Distinct subcategories are identified that provide insights on the current landscape of STSA and related research. Research limitations/implications: This study makes a significant contribution to the theory and practice of SA, and among the key contributions are a systematic understanding of the scale and scope of STSA outcomes; insights on the most efficient design of future STSA programs; and an expanded understanding of the role and importance of STSA programs in international education. Furthermore, a comprehensive STSA outcomes map develops an extensive research agenda. Social implications: While the COVID-19 pandemic currently limits the opportunities for STSA, given its previous popularity, the authors envisage a strong return in the coming years of this form of affordable and valuable global learning. STSA programs have become an important component of higher education and which require considerable resources from participants and educational institutions alike. Therefore, further research is needed to understand the impacts of STSA programs and to further improve program design. Such research will serve to better inform both academic understanding of the phenomenon and educational practice. Originality/value: The study provides the first comprehensive classification of all studied STSA outcomes.
