All instructional and maintenance sessions occured in a standart room at a hotel in city center. Generalization of skills was assessed in a suit-room of hotel.Results indicated that VM, was effective in teaching hotel house-keeping skills to young adults with intellectual disabilities. Skills, which were maintained over time, were further generialized at high levels to suit room in the same hotel. Assessment of video-based non target skills data showed that one participant acquired 100% correct on non target skills while the other three participants, whose performances range from 33% to 66%, could not acquire at such high levels.Key words: Job skills, hotel house-keeping skills, video modeling, intellectual disability, non target skills.
