The search for different experiences in touristic visits brings the necessity of differentiating the tours for tour guides with. Interpretation lies at the heart of this differentiation. This research aims to examine the structure of interpretation performance of tour guides empirically within the framework of E.R.O.T/T.O.R.E model. For this purpose, in line with the literature firstly conceptual structure of interpretation performance and interpretative guiding was determined, then expert opinion was sought with the expression pool consisting of draft statements. After expertising process, the measurement tool was first applied on a sample of 191 participants. For preliminary analysis the performance of items was examined. Second application was conducted to the participants of guided tours which departed from Mersin, Adana, Hatay and 419 usable questionnaires were obtained. Validity and reliability analysis revealed that the measurement tool is valid and reliable with two dimensions. Within the framework of EROT (enjoyable, relevant, organised, thematic) model, interpretation performance of tour guides has a two-dimensional structure as “relevant” and “organized” interpretation. As a result of findings theoretical and practical implications were discussed in the conclusion session. This study is important as being the first study to test this structure in the literature.
