Abstract Objectives: To determine the impact of collaborative program of four different dental faculties in Indonesia toward National Board Dental Exam result Methods: The collaboration activities were conducted intensively in June until August 2014 in four institutions. Progress Test is chosen as the formative test in collaborative activities. Progress Test (PT) is conducted through computer based-test (CBT) and implemented two times with interval 2 weeks. The result of the progress test were statistically analyzed using the Wilcoxon test to assess the comparative result and Spearman correlation test to determine the relationship between the result of Progress Test and the result of CBT in the National Board Dental Exam . Results: Wilcoxon signed rank showing 3 students of second Progress Test (PT 2) have a value lower than the value of first Progress Test (PT 1), 174 students have grades of PT 2 higher than PT 1 and two students have the same results between PT 1 and PT 2. Analytical results Wilcoxon test showed a significant difference between the results of PT 1 and PT 2 (p<0.05). Spearman correlation tests result showed significant correlation between the value of PT 2 with CBT National Board Dental Exam (p<0.01). There are significant correlation showed between score of PT 2 with the success rate in CBT but in weak correlation category (r = 0.475). Conclusions: Collaborative activities with four faculties of dentistry have positive impact on the success rate of National Dentists CBT. Progress test collaborative can be applied in the process of dental education in Indonesia. Keywords: collaboration, progress test
