A case study was conducted with a student leadership body of a private multicultural international secondary school in North-West Province , South Africa, to indicate that the emotional intelligence leadership development challenges of student leaders can be identified through a questionnaire as a measuring instrument, which can then be utilized in promoting training and development of student leaders. The questionnaire results were used to construct emotional intelligence leadership profiles for the 12 participating student leaders, followed by semi-structured interviews with them to verify the results qualitatively. The results of the questionnaire and two of the interviews are reported. It was established that it was possible to develop a reliable instrument to measure the emotional intelligence leadership development challenges of student leaders, which can be used in promoting their training and development.
