A study on examiner variability in assessment by short essay type questions
Journal Title: MedPulse -International Medical Journal - Year 2019, Vol 6, Issue 2
Abstract
Assessment of answer scripts of students is invariably associated with examiner variability. The present study is aimed to analyze the marks awarded for answer scripts of short essay type of questions for examiner variability. The answer scripts consisting of short essay type of questions of final year post graduate students in general surgery at two government medical colleges were assessed independently by two faculty members. The marks awarded were analyzed for variability for each question and total marks using ‘t’ test and correlation for each answer between the two examiners was calculated using Spearman’s correlation. The results showed no significant difference in mean scores between the examiners for most of the individual questions and total marks awarded for the answer scripts and also showed a strong monotonic correlation between the examiners but a significant difference was found in the mean scores between the examiners for two questions. Thus short essay questions are reliable and can be used to assess the cognitive skills. The current study recommends appropriate measures to decrease inter examiner variation by identifying the specific questions of variation.
