The purpose of this paper is to clarify the impression and the value about building cleaning service as mentally-disabled persons' employment. The questionnaire was conducted for special needs school teachers across the nation. As the result of the multivariate analysis, while "Age" and "Information amount to evaluate company" in respondent's attributes were seen a high correlation to value of the building cleaning service, the relations between them were analyzed in detail. In addition, the ease with which mentally-disabled persons were able to work was estimated such as the meaning of multi-employment, the important point to work easily and so on. And the current state of the mentally deficient person who had worked there was defined according to the questionnaire by the only respondents who had offered job guidance about cleaning service.
