The research aims to study and apply a proper statistical method for creating and developing the evaluation model of pre-service teachers’ competency in the 21st century. Data collection process includes an interview, focus group, questionnaire and evaluation. Descriptive statistics, Exploratory Factor Analysis and First and Second - Order Confirmatory Factor Analysis are the techniques used for data analysis. The samples of 1284 instructors and teachers in training unit are collected for the Factor analysis. The study presents 10 factors of the pre-service teacher competency in the 21st Century: (1) the proficiency of professional teachers’ basic subjects, (2) the proficiency to promote learning efficiency, (3) the proficiency of the social context, (4) the learning management skills, (5) the media technology skills, (6) the communication skills, (7) the social skills, (8) the conscious and awareness, (9) the self-practice, and (10) the moral and ethics. The result shows that KMO =0.979 and the Bartlett’s Test shows all indicators are correlated at α= 0.05. The total variance of the components is 79.782%. The fit indexes indicate the consistency of the structure evaluation model with empirical data includes Chi square/df. =1.96, RMSEA = 0.027, CFI =1.00 and GFI=0.93. The validity is measured by t>|1.96| at α=0.05 and the reliability of indicator using R2 are between 0.62 to 0.83 for all 60 indicators. The construct reliability of this model are between 0.91 - 0.96 indicating a good reliability and the construct validity is consistent with standard criterion. The model includes 5 evaluation factors: focus group, scope, procedure, judgment, and report.
