Abstract

This training event will be particularly beneficial for awarding body subject staff and assessors involved in setting assessment material, providing examples of successful and unsuccessful items, how they are identified and what questions to ask about the assessments on which they work.

It is an introduction to test and item evaluation covering the item level statistics used across a range of Cambridge Assessment’s qualifications. It introduces the concepts of omit rates, facility values, discrimination indices, bias or Differential Item Functioning, and analysis of multiple choice items. Parts of the session are delivered in a workshop style to allow participants to build confidence in interpreting statistical analysis of assessments. This session assumes a basic knowledge of statistics, including the concepts of mean and standard deviation.
