The proportional two stage random sampling was applied for 400 STEM education teacher competencies under the secondary educational service area office 19. <br> The research tool was a five level rating scale questionnaire. There are 63 items. Data was analyzed by using: percentage, mean, standard deviation, skewness, kurtosis, chi-square, pearson’s product-moment correlation coefficient and confirmatory factor analysis. The research findings were as follows:</p><ol><li>The factor of STEM education teacher competency has three factors: Knowledge, Skills and Attribute. The factor loading of three factors are 0.26, 0.27 and 0.28 respectively and factor scores were between 0.01 to 0.26.</li><li>The test result of the consistency of structural equation model with the empirical data showed that the Chi-Square goodness of fit test at 42.15 with 49 degree of freedom; p-Value = 0.75; Goodness of Fit Index (GFI) = 0.98; Adjusted Goodness of Fit Index (AGFI) = 0.97; Comparative Fit Index (CFI) = 1.00; and Root Mean Square Error of Approximation (RMSEA) = 0.00. Thus, the model has a good consistency with empirical data.</li></ol> ER -
