In the past, the students were scored manually by facilitators. The scores were checked and transferred to a spread sheet by at least three administrative assistants. This massive workload delayed the process of finalizing scores in each study block which meant students with low scores were not identified promptly. Consequently some of these students did not pass their study. An electronic scoring system was implemented to improve the scoring process. The system facilitates the adminis- trative assistant to create a scoring form, manage scenario details, store data, perform backups, and export data. One year analysis showed the major effect of the new system was that it significantly reduced the time taken for the scoring process. Finally, the improvement of the scoring system decreased the number of repeat student from 10 (on average between 2008 and 2011) to 2 students in 2012.
