The purpose of this empirical service research is to analyse the reliability of the dimensions and items of a new measurement scale for community-based rehabilitation service excellence culture. This survey research employed the quantitative approach with structured questionnaire survey and a total of 1029 questionnaires were collected for analysis. The empirical research discovered six dimensions (thirty-eight items) for the rehabilitation service excellence culture, namely: Trainee, Competitor, Inter-functional Coordination, Excellence-driven, Long-term, and Employee orientations. The multi-sample reliability analysis was done and the scale reliability was found to be consistent.  This reliable multi-item scale is potential for effective and meaningful service excellence culture management to care for people with special needs.
