This training event will help you to gain a better understanding of the concept of assessment reliability, how it is conceptualised, calculated and how it should be interpreted. It is aimed at those responsible for the development and quality control of assessments.
This event provides an overview of the ways in which the reliability of a test is conceived and calculated. It includes an introduction to the relationship between reliability and classical test theory. The presentation was well structured and thought through. The presenter pitched the level very well and with enthusiasm, and he clearly understood the concepts at a very deep level when asked."
The reliability of marking and reliability relating to the choice of questions included within an examination will both be covered in this training session.
Tom will explore the different ways in which reliability can be presented to an external audience and will invite participants to look at the advantages/disadvantages of each. The session will also explore which factors may affect the reliability of a test.
