Aim: The aim of the study is to develop a scale to determine the customer loyalty levels of customers receiving service from sports centers serving in the public or private sector.

Methods: The research was designed as an original study in the general screening model.

Results: KMO= 0.784 and Barlett test χ2 = 6235,211 (p <.001) were conducted to test the suitability of the data for factor analysis. It was determined that the item factor loads of the scale ranged between 0.35 and 0.82. As a result of the exploratory factor analysis, a structure with 40 items and three factors that explained 67.12% of the total variance was obtained. It was concluded that the correlation values (.191- .311) between the sub-dimensions were appropriate, and the fit indices of the scale were significant (X2=726,66 sd=408, p=.00, X2/sd=1.78).

Conclusion: In the light of the analyses made and the findings obtained, it was concluded that the CLSSC is a valid and reliable scale that can determine the level of customer loyalty among receiving service from sports centers.
