The study of competencies in student affairs began more than 4 decades ago, but no instrument currently exists to measure competencies broadly. This study builds upon previous research by developing an instrument to measure student affairs competencies. Results not only validate the competencies espoused by NASPA and ACPA, but also suggest adding a new competency and dividing some existing competencies into separate ones. Competency strengths, competency weaknesses, and implications for current practice and future research are discussed.
