This study outlines the analysis of a post trade curriculum development system called Dacum. The term Dacum is an acronym for Developing A Curriculum. The system is generally considered to be a standard approach to competency based curriculum development and is used to plan the technical and vocational programmes for technician engineers. The analysis of the work roles for technician engineers is to show the range of activities they are engaged with in industries. Data for the study was collected through a survey conducted on behalf of New Zealand Engineering Industry Training Board. The generation of Dacum - charts and subsequent task analysis identifies the skills and beliefs required by technician engineers to perform successfully on a job and shows the relevance of the polytechnic studies as applied to their work. This also serves as a guideline to review curriculum design and training programmes for technician engineers that will render more effective practical application in their occupational roles.
