Introduction: In various educational streams including health sciences, the students are evaluated through subjective and objective questionnaire. Multiple choice questions are to be evaluated for meaningful contribution to the marks obtained by students. This assessment or item analysis is done to make question bank to find out the low achievers. Material and methods: This study was conducted on 100 first year MBBS students of GMC, Haldwani (UK) on completion of a part of Anatomy. Fifty multiple choice questions were given for item analysis. Difficulty index, the p value and Discrimination index (DI), of multiple choice questions were assessed. Results: Difficulty index of 24 (48%) items were in acceptable range (p=30-70%), 20 (40%) were optimum range (50-60%) and 6 (12%) were unacceptable range (<30%). Discrimination index of 12 (24%) items were excellent > 0.35, 8 (16%) had good discrimination 0.25-0.34, 26 (52) were acceptable 0.20-0.24 and 4 (8%) items were in unacceptable range (<0.20) Conclusion: Difficulty index, p value >70% and Discrimination index, D value <0.20 needs modification of item or MCQ. Thus this analysis of questions can be useful for development of better questions in the future. MCQ items having optimum Difficulty Index and excellent Discrimination should be regarded as best framed questions.
