Assessment Analysis: How It Is Done

Abstract

This article was migrated. The article was not marked as recommended. This article elaborates assessment analysis, a topic recently introduced in another article published in January 2017 by the same author in AMEE MedEdPublish. The formulae used to generate difficulty index and discrimination index of examiner-scored assessments as well as whole papers like MCQ are described in simple terms. The formulae used for assessment analysis are aligned to those established decades ago for item analysis. A step-by-step guideline is included to enable those interested to practice assessment analysis. The formulae, an Excel worksheet showing index calculations and the interpretation of index values are also included.
