Abstract：

This study aims to explore the current status of Computer Aided Drawing (CAD) teaching at mechanical departments in Colleges and Institutes of Technology and Vocational Education and the students' learning situation so as to provide reference for efforts to improve the teaching content of CAD in the future. The first part of the study focuses on theories related to the required competency and reviews literature in this field in order to set a theoretical foundation for the study. The next step is to develop a questionnaire for interview on CAD teaching by means of experts' panel discussions. The final part of the study involves a site visit to mechanical departments in Colleges and Institutes of Technology and Vocational Education for the purpose of shedding more light on the current situation of CAD teaching and including a rich gamut to opinions into the study. Based on the analysis of the result of questionnaire, the study reaches the following conclusions:
1. CAD course should be divided into two semesters and taught to sophomore. Colleges should provide the teacher with opportunities for further CAD studies while offering the student prep-courses on engineering graphics.
2. The learning status of CAD-related competency items: The competency items that are highly essential include Specifying Tolerance and Fit, Drawing Sections, Dimension, Note and Precision, Construction of 3D concepts, Making 3D Detail Drawing, etc. The competency items that have reached a higher degree of satisfaction include setting up computer peripherals, Dimension, and understanding processing methods and processes, etc.

Keywords：CAD, competency items, engineering graphics
