A DEVELOPMENT OF TRAIT INDICATORS FOR SERVANT LEADERSHIP OF TEACHERS IN BASIC EDUCATION SCHOOLS AND VOCATIONAL SCHOOLS UNDER THE MINISTRY OF EDUCATION

Abstract

The study conducted a second-order Confirmatory Factor Analysis (CFA) of servant leadership of teacher in basic education schools and vocational schools under the Ministry of Education, with findings based on empirical data. The sample for this research consisted of 1,200 participants, teacher in basic education schools, and teacher in vocational schools under the Ministry of Education, selected through multi-stage random sampling process. The research instrument was a five-point rating scale questionnaire that underwent content validity verification. The results were analyzed to determine the Item-Objective Congruence (IOC), with values ranging from .80 to 1.0. The item discrimination indices of the questionnaire ranged from .46 to .80, and the reliability analysis, using Cronbach's alpha coefficient, yielded a value of .95. The statistical method used for data analysis was CFA. The study results yielded six trait indicators for servant leadership of teacher in basic education schools and vocational schools under the Ministry of Education of six factors, include: valuing others 3 indicators, developing others 4 indicators, developing communities 4 indicators, demonstrating virtue 5 indicators, supporting leadership 4 indicators, and exercising shared leadership 5 indicators. The results of the examining the Goodness-of-Fit Index of CFA found the model fit indexes based on the empirical data were the Relative Chi-Square. (χ²/df) = 1.242; RMSEA=0.022; SRMR=0.038; GFI=0.958; CFI=0.995; TLI=0.993; NFI=0.975; IFI=0.995. The factor loadings of six factors were from 0.739 – 0.914 and the reliability was at 0.546 – 0.835, indicating that all factors exhibit strong and acceptable loadings. The overall result of CFA measurement model demonstrates a good level of fit and construct validity.
