Introduction to Classical Test and Rasch Measurement Theories IMEDM401

In this course you will gain an introduction to the historical development of test theory and how modern theory has superseded traditional theory in many applications, especially in large-scale assessments. In particular, you will learn how Rasch measurement incorporates, elaborates and better achieves the goals of traditional test theory.

Upon successful completion, you'll receive:

  • Six PD Points - stackable for unspecified academic credit in award courses
  • A Certificate of Achievement
  • A UWA Plus Professional Development Transcript, listing all successfully completed micro-credentials

Why study this course?

  • Students will be able to explain the basic principles of Rasch measurement theory in the social sciences

  • You will understand the principles of traditional test theory in terms of Rasch measurement theory

  • Learn to use a range of diagnostic tools in order to assess the quality of items in constructing assessment instruments of achievement, knowledge and attitude

  • Learn to apply software in analysing assessment data

Who should study this course?

  • Professionals in assessment and measurement of performance and attitude who know traditional test theory and are interested in learning the principles of modern test theory and Rasch measurement.
  • People in education, psychology, health care and health sciences who are concerned with outcome measurement.
  • People familiar with Rasch measurement and modern test theory (item response theory) who want to consolidate their understanding of first principles.
  • Students enrolled in higher degree studies and who require knowledge and evidence of studying educational and psychological measurement, especially an introduction to traditional and modern test theory.

How does it work?

Assessment comprises of nine assignments

What's next after this course?

The Psychometric Laboratory does research in all areas of Rasch models for measurement, in particular epistemological, applied, and in software development. This is an opportunity to study with researchers who have made advancement in all these fields.
