The foundations of measurement and assessment in medical education.

As a medical educator, you may be directly or indirectly involved in the quality of assessments. Measurement has a substantial role in developing the quality of assessment questions and student learning. The information provided by psychometric data can improve pedagogical issues in medical education. Through measurement we are able to assess the learning experiences of students. Standard setting plays an important role in assessing the performance quality of students as doctors in the future. Presentation of performance data for standard setters may contribute towards developing a credible and defensible pass mark. Validity and reliability of test scores are the most important factors for developing quality assessment questions. Analysis of the answers to individual questions provides useful feedback for assessment leads to improve the quality of each question, and hence make students' marks fair in terms of diversity and ethnicity. Item Characteristic Curves (ICC) can send signals to assessment leads to improve the quality of individual questions.
