Abstract: The purpose of this study was to revise the content of the Work Performance Rating Scale (WPRS) as a valid assessment tool for sheltered workshop workers. A focus group of 11 sheltered workshop workers was recruited to collect their opinions about the relevance of the WPRS from the service users' perspectives. A panel of 23 frontline practitioners who had experience in using various work assessment instruments provided at their work setting was recruited to review the content of the WPRS. A 14-item amended version of the WPRS with five new items added was proposed based on the opinions of service users, frontline practitioners, and the concept of the Minnesota Theory of Work Adjustment (MTWA). An expert panel of 12 professionals at the senior level from various vocational rehabilitation settings was recruited to comment on the content validity of the 14-item amended version of the WPRS. The expert panel agreed that the amended version of the WPRS was related to the concept of job satisfactoriness which could be used to assess the work performance of sheltered workshop workers. Thus, the use of the MTWA for improving the content validity of the WPRS to assess the employability of sheltered workshop workers was supported by the findings of the study.
