The low absorption of the workforce in the vocational high school graduates indicates their lack of expertise and competency. It urges to improve their work skills to meet the demand of work. This research aims at developing a Lean-based learning model to enhance the work skills of vocational high school students. This research categorized as development research uses the modified Borg and Gall method. The Lean-based learning model was tested through three stages, namely its validity, effectiveness and practicality. Respondents of the research are vocational high school students, vocational high school teachers and industry practitioners in Indonesia. The model was validated by some experts and FGD results. The effectiveness of the model was tested by an experimental with a posttest only control group design. The population of the experiment was students of the Vocational High School who were doing an industrial experience in some industries, which followed a work shadowing strategy, the sample is chosen by random sampling; data were collected to develop a performance test. Two questionnaires were used to evaluate the practicability of the model according to the perceptions of the teachers and students of the Vocational High School. Based on the research, the developed learning model can be categorized as “good” in case of its validity, effectiveness, and practicality. It means that the lean-based learning model is valid, effective and practical. The conclusion of research is that lean learning model is one of the alternatives to improve work skills competency among vocational high school students to fulfill the industrial demand.
