Rasch analysis constructs linear measures from scored observations, such as responses to multiple-choice questions, Likert scales and quality-of-life assessments. This course covers the practical aspects of data setup, analysis, interpretation and reporting. Simple test linking and equating designs are addressed, and supporting theory is presented conceptually. The course will use a time-limited version of Winsteps software, and Microsoft Excel is used extensively.

What Our Students Say
This has given me a great overview of Rasch and introduced me to Winsteps which I will use instead of Quest in the future. Thanks, the course was very useful and was very clear and well explained, especially for a beginner like me!

Additional Course Information
Organization of Course
This course takes place online at The Institute for 4 weeks. During each course week, you participate at times of your own choosing – there are no set times when you must be online. Course participants will be given access to a private discussion board. In class discussions led by the instructor, you can post questions, seek clarification, and interact with your fellow students and the instructor.
At the beginning of each week, you receive the relevant material, in addition to answers to exercises from the previous session. During the week, you are expected to go over the course materials, work through exercises, and submit answers. Discussion among participants is encouraged. The instructor will provide answers and comments, and at the end of the week, you will receive individual feedback on your homework answers.
This is a 4-week course requiring 10-15 hours per week of review and study, at times of your choosing.
Homework in this course consists of short answer questions to test concepts and an end of course measurement construction project.
Practice tasks are also provided to allow participants the opportunity to practice the concepts being taught with provided data sets.
In addition to assigned readings, this course also has supplemental readings available online.
All necessary study material is provided online by the instructor.
The course will use a time-limited version of Winsteps software available when the course starts. Microsoft Excel is used extensively. Note: Winsteps does not run on native Macintosh OS; you will need to be running Windows.
