Study abroad has the potential to lead to perspective transformation, the highest level of learning. Instruments are lacking to quantitatively measure the effectiveness of the study abroad experience in terms of student learning outcomes. Obtaining such data could be used to better evaluate teaching methods. Informed by qualitative research, an instrument was developed to measure transformation from study abroad. The scale content validity index was 0.82, demonstrating strong validity. Although further testing is needed, this instrument presents a way to examine the impact of study abroad so that learners may be better prepared to attend to the global community.
