The study aims to describe (1) the development stages of the manual arc welding job sheet and (2) its validity. It is a Research and Development (R & D) of which the data were collected by means of non-test instruments, namely the closed-ended questionnaires with the 5-scale responses. The data were collected from the three research participants acting as the material and media experts,namely two lecturers in the Mechanical Engineering Education Study Program, Faculty of Engineering (FE), Yogyakarta State University (YSU), and a teacher of the Basic Welding Technique subject. The job sheet development stages were adapted from Thiagarajan's model, namely the Four-D model covering the definition, design, development, and dissemination. Data were analyzed quantitatively by means of the descriptive statistics. The results of the material evaluation by the material expert I prove that the job sheet is categorized as Appropriate (with the total score of 145 or 82.9%) and Very Appropriate based on the material expert II with the total score of 153 (87.4%). Besides, in terms of the media, the job sheet is Appropriate based on the media expert I (with the total score of 207 or 82.8%) and Very Appropriate based on the media expert II (with the total score of 215 or 84.4%). © Published under licence by IOP Publishing Ltd.
