The data in this thesis were taken from DLIFLC and only students from the four principal services with valid DLAB scores were considered for this study. Also, as DLI is concerned with students who do not make the grade academically, entries having administrative attritions were not considered. Four logistic regression models were analyzed for the purposes of this study: Graduation of students across all four categories of languages taught at DLIFLC, graduation of students in Category I languages, graduation of students in Category III languages and graduation of students in Category IV languages. The results of this study can assist DLIFLC in investing its resources in students with the best chances of success and assist the staff in identifying the weaker students from the onset of the course. / Major, Republic of Singapore Air Force
