This study aimed at validating situation awareness test using confirmatory factor analysis (CFA). The participants were 136 nurse anesthetist students from multistage sampling. The research instrument was situation awareness scale 48 items developed from Endsley’s situation awareness concept with content validity ranging from .57 to .86 and internal consistency reliability was .75. The collected data were analyzed with confirmatory factor analysis for construct validation. The results were as follows: the confirmatory factor analysis of situation awareness model had 3 factors namely perception, understand and projection. The perception factor consisted of 2 indicators collect and inspect. The factor loadings were .45 and .66 respectively. The understand factor consisted of 2 indicators interpret and conclusion. The factor loadings were .61 and .65 respectively. The projection factor consisted of 2 indicators practice and event. The factor loadings were .74 and .99 respectively. The validation of goodness of fitted model yielded a Chi-square of 3.84, p=.57 at a degree of freedom of 5 (GFI=0.991, AGFI=0.961 and RMSEA= 0.000). The situation awareness scale of nurse anesthetist students has construct validity.
