The Cross-Cultural Competence Scenario-Based Assessment (3C SBA) is a professional development tool that can help individuals identify their cross-cultural aptitude. The 3C SBA uses subjects’ reasoning skills to identify 3C strengths and developmental needs requiring improvement prior to international assignments or overseas deployment. The overall purpose of this assessment is to provide opportunities to enhance deficient 3C reasoning skills, and/or leverage existing reasoning skills to thrive in culturally-diverse contexts.
