Recent advances in computer-related technology and the availability of technology to everyone at affordable cost have made it possible to use such technology in every aspect of teaching-learning. Educational institutions are increasingly using optical mark readers (OMRs) which also feature software that calculates difficulty index and discrimination index in addition to correcting hundreds of OMR mark sheets in a matter of seconds to minutes which would otherwise take many man-hours. We explore how useful the calculations of discrimination index by optical mark readers are in item analysis of single best answer MCQ tests with small student numbers.
