Abstract: The study aims to identify quality dimensions, and provide valid and reliable measurement instruments for the service quality of TQM education institutions from the external customers' perspective. The external customers of three traditional universities in a developing country were involved in the study. A five-point Likert scale 26-item instrument was developed to elicit information from the selected participants. Out of 1,050 questionnaires administered, 834 were returned with 819 being eligible responses with the response rate of 79.4%. Confirmatory factor analysis yielded same five principles with the 26 items which accounted for 71.3% total variance explained. The internal consistency with an overall KMO value of 0.97 indicated higher reliability. The instrument is found to be valid and reliable. Further studies could be done to capture more public and private universities for comparison. The instrument could be used periodically to assess the service quality performances by the education institutions.
