Abstract
This research aimed to analyze the confirmatory factor structure of digital competency among basic education school administrators. The sample consisted of 400 administrators under the Udonthani Educational Service Area Office for the academic year 2025, selected through proportional stratified random sampling and simple random sampling by drawing lots from all schools. The research instrument was a five-point Likert scale questionnaire with a reliability coefficient at .997. Data were analyzed using frequency, percentage, mean, standard deviation, skewness, kurtosis, Pearson correlation coefficient, Kaiser-Meyer-Olkin (KMO) measure, Bartlett’s test of sphericity, and confirmatory factor analysis (CFA).
The results showed that:
- The correlation coefficient, KMO, and Bartlett’s test indicated that all main components of digital competency were positively correlated at the .01 significance level, with correlation coefficients exceeding .30. The KMO value was .911 (greater than .60), and Bartlett’s test produced an approximate Chi-square value of 2398.859 significant at the .05 level. These findings confirm strong inter-variable relationships and suitability for factor analysis.
- The confirmatory factor analysis was conducted to construct a structural equation model (SEM) to examined the consistency between the theoretical model and empirical data. Indicators were grouped under 8 main components, 29 subcomponents, and 70 indicators. After model adjustment, the model demonstrated excellent fit with empirical data: χ² = 268.355, df = 240, χ²/df = 1.118, P-value = .101, RMSEA = .017, CFI = .996, TLI = .993, GFI = .957, AGFI = .922, RMR = .006, and Hoelter index = 413.000 at the .001 significance level.
All statistical indicators met acceptable criteria, confirming that each indicator properly aligned under its subcomponent, and each subcomponent corresponded to its main component. Therefore, the digital competency model for basic education school administrators was found to be highly consistent and well-fitted with the empirical data.
