The purpose of this article is to present the results of a research which assessed whether the Knowledge Acquisition Programme and the Non-Commissioned Member Executive Professional Development Programme contributed to the Non-Commissioned Members’ effectiveness as senior leaders in the Profession of Arms within the Canadian Armed Forces. Thirty-seven Programme graduates from 2006 to 2015 received a questionnaire containing seven closed-ended general information questions and twelve open-ended programme/course specific questions. Seventeen graduates responded to the questionnaire. Manual coding was used to identify main themes and sub-themes. The research findings determined that both Programmes contributed to the effectiveness of senior leaders in the Profession of Arms within the Canadian Armed Forces. However, some caveats were expressed, and recommendations brought forward to enhance the Programme and to improve its future deliveries.
