The article summarizes the effects of an eight-week short-term study abroad program (four weeks in the United States and four weeks in Germany) on students' global competence. Students' global competence was measured with the Global Competence Aptitude Assessment (GCAA) before and after the eight-week summer program. Data was collected from three summer programs and a total of 42 students participated in the study. The results indicate that students made statistically significant improvements in several dimensions of global competence but also statistically declined in one area. Suggestions for possible curricular and programmatic changes were made that may be put into place to provide more opportunities for the development of global competence in future iterations of this summer study abroad program.
