WEB18 Test Security: The Psychometric Side of Test Security


This on-demand webinar introduces test security from a psychometric perspective. Start by learning a background for relevant threats to test score validity.  Most are related to “cheating” in a broad sense, but not all; some might be due to low engagement or other issues that are not malicious but nevertheless invalid. Next, learn a framework for evaluating threats to validity, how they might impact your programs, how they might present themselves in data, and what you can do to deter and detect the threats. Finally, delve deeper in the psychometric forensics that are available, what messages they can provide, where their limitations reside, and options for both free and commercial software to calculate them.

Learning Objectives

After attending this on-demand webinar, you will be able to:

  • Identify the threats to score validity typically related to test security that are present in test data.
  • Evaluate threats and have an understanding how to fit that into a test security plan
  • Identify the types of psychometric forensics available to find test security related threats to score validity.
