Nowadays the assessment of Sport Services is one of the most studied facts due to the need to understand the users’ behaviour and for the use of the information that the organizations obtain through this type of research. There are different measuring instruments but they have several limitations. The aim of this study is to validate an instrument and verify its reliability as a means of assessment of the services provided by the different sport organizations. To do this a questionnaire was made, composed of three areas: perceived quality, satisfaction, and perceived value. A statistical analysis, an exploratory factor analysis, and a confirmatory factor analysis were performed on the items and the validity was determined. The results were embodied in a final questionnaire consisting of eight dimensions and 25 items, able to assess the perceived quality, satisfaction and perceived value of the service provided by the sport organizations.
