This study aimed to calculate the mean reliability of scores obtained from Unified Theory of Acceptance and Use of Technology (UTAUT) scales and to explore the variability in reliability estimates within the educational context. For this purpose, a Reliability Generalization (RG) meta-analysis study was conducted using 484 reliability estimates from a total of 464 studies. In the study, reliability estimations for 9 factors of UTAUT models (Venkatesh et al., 2003; Venkatesh et al., 2012), namely Performance Expectancy, Effort Expectancy, Facilitating Conditions, Social Influence, Hedonic Motivation, Price Value, Habit, Behavioral Intention, and Use Behavior were analyzed. Cronbach's alpha and Composite Reliability (CR) reliability estimates were examined using the random effects model. As a result of the study, the mean Cronbach's alpha reliability estimates were found between 0.83 and 0.89, the mean CR reliability estimates were found between 0.87 and 0.92, and all mean reliability estimates were found statistically significant according to the random effects model. Moderator analysis revealed that the number of items, and the number of response options had a statistically significant effect on Cronbach's alpha, and the number of items, sample group, and number of response options had a statistically significant effect on CR reliability estimates only for a few factors, while the moderators of sample size and gender (% female) did not have a significant role in explaining the variability in reliability estimates.
