Abstract :

AIM: To assess the quality of multiple choice questions and take further intervention MATERIALS AND METHODS: Total of 30 multiple choice questions were taken to find out difficulty index ( DIF I) , discrimination index ( DI) , and distractor efficiency (DE) . RESULTS : 21 items showed DIF I between 30–70%, 9 items had >70% . Out of 30 items, 21 had DI index between 0.2 – 0.35 while 9 had > 0.35. None of the items showed DI < 0.15. Out of total 30 items, 18 ( 60%) had nil NFD {DE= 100%} , 6 ( 20%) had 1NFD { DE= 66.6%}, 4 ( 13.3%) had 2 { DE= 33.3%} and 2 (6.7%) had 3 NFDs { DE=6.3%} . Thus mean � SD value for DIF I came out as 58.84 � 19.16 % and for DI and DE came as 0.31 � 0.14 and DE = 77.76 � 31.98 respectively. CONCLUSION : This study emphasize that questions having average difficulty and high discriminating power with presence of functional distractors should be incorporated into further tests. Very difficult and very easy items need to be properly reconstructed.
