            This descriptive research study was conducted to analyze the confirmatory factors of competency in Rational Drug Use of the nursing graduates based on the competency framework of drug prescribing. The sample was the data on Rational Drug Use competencies of 4,263 nursing graduates who completed the Bachelor of Nursing Science program in the academic year 2018. The data was collected using the Rational Drug Use competency questionnaire for nursing graduates. The questionnaire had the content validity check with IOCs between 0.75 - 1 and greater than 0.5 for each item. The reliability was tested yielding a Cronbach alpha coefficient of 0.96. The results of the confirmatory factor analysis revealed that the Rational Drug Use competency model of nursing graduates based on competency framework of drug prescribing was consistent with the empirical data. The Goodness of Fit Index (GFI) of the model was .980, the Adjusted Goodness of Fit Index (AGFI) was .972, the residual of the Root Mean Square (RMS) was near 0 with a value of .005, and the Root Mean Square Error (RMSE) was .019.
