Abstract

The objectives of this research were to: 1) study the level of educational quality assurance competency of school administrators, and 2) examine the educational quality assurance competency model developed for school administrators in harmony with the empirical data. The research participants were 500 school administrators in primary and secondary education area offices in Nakhon Ratchasima, Buriram, Surin, and Chaiyaphum provinces, selected through stratified random sampling. The instrument used in the research was a measure of educational quality assurance competency of school administrators with an IOC value between 0.80–1.00, item discrimination between 0.47–0.75, and a Cronbach’s alpha reliability coefficient of 0.93. Data were analyzed using descriptive statistics, Pearson product-moment correlation, and second-order confirmatory factor analysis with maximum likelihood estimation in LISREL.

The results showed that: 1) The overall level of educational quality assurance competency of school administrators was at a high level (M = 3.51, SD = 0.46). When considering each component, the characteristics component obtained the highest mean (M = 3.58, SD = 0.83), followed by knowledge (M = 3.48, SD = 0.45) and skills (M = 3.47, SD = 0.71), respectively. 2) The quality assurance competency model of school administrators, specified as a second-order CFA with three first-order factors (Knowledge, Skills, Characteristics) loading on a general competency factor, was consistent with the empirical data: χ² = 1.19, df = 3, p = 0.756, χ²/df = 0.39, GFI = 1.00, AGFI = 0.99, RMSEA = 0.00, and RMR = 0.00.
