In the field of language testing and assessment, a test's predictive validity can be considered one of the most frequently discussed validity in test validation because it mostly addresses the question of test accuracy as a predictor of academic performance. Hence, this study evaluates the predictive validity of the Vietnamese Standardised Test of English Proficiency (VSTEP) according to the Vietnamese Framework for Foreign Language Competency in order to determine the academic success of students by finding the correlation between VSTEP test scores and their cumulative grade point average (CGPA). The results indicated that there were some existing correlations between VSTEP scores and CGPA; however, these correlations were weak. In precise, the correlation between VSTEP overall score and CGPA had a better predictive value and the VSTEP Writing test showed a bit higher predictive evidence than the other three components: Listening, Reading and Speaking. The study finally covers some recommendations for the use of in-house language tests.
