Abstract
In this study, we have tried to improve the effectiveness of counseling through developing support index and utilized the index for student counseling from whom encountered various issues during their college life. In order to develop the support index, about 20,419 records were analyzed based on the results of learning from the training data for the last six years. Individual factors for students were set as descriptive variables, and students’ academic continuity and dropout were analyzed through logistic regression. As a results, firstly, the input of explanatory variables was significant in the model fit (p < .001). Secondly, the number of breaks, the number of academic records, and economic factor1 have a strong impact on the support index, but the number of enrollment semester, the average of grades, and the number of scholarships have a negative effect on the support index. Lastly, economic factor2 and the total amount of scholarships were shown significant, but the impact on the support index was minimal. Based on the results, the support index, which indicates the degree of support required was proposed to increase the efficiency of student counseling.
