Public universities in Bangladesh arrange admission test to judge the students' merit before the enrollment. Academic results of previous examinations (SSC and HSC) are also considered in the admission procedure. There are some disputes regarding the importance of admission test besides the previous academic records. The universities emphasize on the admission test while the government authorities ponder it as a burden for the students. This study has made an attempt to examine the importance of admission test in selection procedure utilizing a particular year admission test database of Shahjalal University of Science and Technology (SUST). Univariate and bivariate analyses along with regression models were used to analyze the data. The results indicate that students with higher score in both SSC and HSC examinations had higher possibility to be eligible for enrollment. However, a vital proportion of applicants with maximum GPA 5.00 in both examinations did not qualify in merit and waiting position. The results also show association and moderate positive correlation of admission test score with SSC and HSC results. Finally, regression analysis indicates that though the contributions of the SSC and HSC results on admission test scores are significant, the variation in admission test scores is not much explained by the previous records. Such findings recommend arranging admission test, besides academic qualification, to select the eligible applicants for enrollment in public universities.
