I reconsidered the work learning to bring up life management skills aimed at the social and vocational independence of the students with the mental disabilities in special support class and newly conducted with educational practice based on the subject "carrier management". In this study, we took up the practice of "food processing" and analyzed the students' behavior and description by adapting an evaluation standard, which involved the point of view of the evaluation and basic, transferable skills. As the result, we confirmed that the students enhanced a feeling of self-affirmation through their behavior and description. On the other hand, we thought that considering the students' stage of development and the linkage between other subjects, the important points of the instruction should be made clear.
