Admission criteria and academic performance in medical school

BACKGROUND: Different variables have been used to predict the academic performance of students in medical schools. The aim of this study was to assess the effect of demographics, admission system, and high-school background on the academic performance of medical students. METHODS: We conducted this longitudinal cohort study on 808 students admitted to the Faculty of. Medicine at the University of Jordan (Amman, Jordan), in the years 2012 and 2013. Admission pathway, and academic performance data were collected and analyzed. RESULTS: A total of 808 students [i.e., 426 (52.7%) females, and 382(47.3%) males] were identified. Admitted students were holding 17 different types of high school degrees, and were accepted through 6 different quota pathways (open competition [National unified admission], underprivileged [“Makrumah”], parallel, children of university staff, international students, and others). Students admitted through the open competition and the underprivileged quota(Makrumah) were more likely to graduate on time and had higher graduation grades while students admitted through the parallel, international and others quota were more likely to fail and had lower graduation grades. Regarding highs school degrees, the students that were more likely to graduate were those with IB and the Jordanian high school degrees. The highest graduation GPA was for IB students followed by SAT, IGCSE as well as Jordanian and Syrian high school degrees respectively. IB, Jordanian, Kuwaiti and IGSC high school grades were significantly correlated with the graduation GPA. CONCLUSIONS: Admission criteria such as type of high school degree and grades as well as admission pathways can predict the likelihood to graduate and the graduation GPA of medical students. Open competition and underprivileged admission pathways as well as IB, IGCSE and Jordanian high school degrees seem to be better predictors of student performance in the medical school.
