The purpose of this study is to construct and validate a multidimensional measurement of training design competencies (TDC) by using three stages (N=497). These competencies include ADDIE training system (analysis, design, development, implementation, and evaluation) and consultation with subject matter experts (SMEs) when human resource professionals engage in a training job. Exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) were conducted. The results demonstrated that the training design competencies were best represented by three dimensions: training planning, training outcome, and the consultation with SMEs. This study offers human resource-related practitioners a valid instrument to develop their professionals and to organize effective training programs.
