Poor competency of construction workers in the construction industry is considered one of the most discouraging human resource issues in developing countries. This paper reports an investigation into the competency level of Indonesian migrant workers in the Malaysian construction industry. Data from this research was collected from the survey questionnaires with 300 Indonesian migrant workers. Results indicated that the levels of knowledge, skill and attitude among Indonesian migrant workers towards the trades in the construction industry only showed moderate levels. Suggestions for ways to overcome skill gap among Indonesian migrant workers were given in order to enhance their competency level in the construction industry.
