Addressing the Potential for Bias in the Development and Scoring of Performance Examinations
Clarence "Buck" Chaffee
All tests are subject to influence of the authors’ human proclivity to reflect their own experience and background. They are the “subject matter experts” and are charged with deciding what is important and what is true or correct. And theoretically, if you have a diverse enough group of experts their collaborative decision-making will override the influence of individual backgrounds and preferences. Groups however can all share the same biases and it is dependent on the test designer and developer to make the conscious efforts to minimize inappropriate bias. This is especially important in performance-based testing where the number of measurable responses is generally small and especially when human scoring is involved.
This presentation looks at the subtle types of bias that are possible in the design of performance tests and human scoring of those exams and it explores approaches to identify and measure bias and reduce the impact of it in the final testing decision.

The Human Element: Building Structure for Standardized Performance Tests
Vicki Gremelsbacker &
Performance testing offers a unique opportunity to rate practitioners in real-world settings, putting their knowledge and skills to the test as they will actually be used. However, the raters are practitioners as well and can introduce additional variation – positive and negative – to the rating process based on their own experiences. Both candidates and raters deserve a scoring system that levels the playing field to ensure the credibility of the credential.
How can an organization build a performance exam that recognizes and neutralizes rater bias?
In this interactive session, we will explore the real-world experiences of the Certification Council for Professional Dog Trainers® (CCPDT®) as they developed their performance exam, the Certified Professional Dog Trainer – Knowledge and Skills Assessed (CPDT-KSA®). Working closely with Professional Testing Corporation (PTC), CCPDT developed a rating process that minimizes rater bias and balances the scores from each member of the rating panel.
Presented by both CCPDT and PTC, we will provide attendees with practical information and processes that can be implemented in their own performance testing initiatives. The discussion will address the importance of developing a thorough rubric that neutralizes rater bias, including technical specification items, gated items, and scored items. We will also highlight the value of a formal rater selection, training, and debrief process to increase rater accuracy and consistency and to ensure that the exam remains standardized across administrations.

How Good Is Good Enough: Standard Setting for Performance Tests
Mark Terry, Greg Applegate, & Ellen Julian
Decisions about how to score performance tests impact the options available for setting passing standards. The two activities should be considered as a unit, even if the final decision about the passing standard must wait until performance data are available. Decisions about whether compensation across cases will be allowed and whether some actions (or lack thereof) are fatal (i.e., trap-door/gated items) will have game- changing implications for standard setting. This presentation will address both the psychometric and practical aspects of these complicated decisions. Data from the National Registry of EMTs psychomotor examination for paramedics will illustrate the relationships among the various approaches and their experience with setting passing standards for performance tests will inform the discussion of the practical implications of different approaches.

Keeping up With the Softwarians – A Look at Developing, Testing, and Validating Exam Performance in the Age of Frequent Software Update Cycles
Jefferson Hansen, Pat Hughes, & Ty Kenworthy
The rapid pace of software and service updates most companies embrace today can cause significant challenges for exam developers who use live or simulated software in their exams to assess candidate skills. In addition to changes to ODs and exam items, PBTs require additional development, testing, and checks for relevance. Certiport and ITS have confronted this challenge for all of the live-in-the-app exams we deliver. We will first present the challenges and some solutions we’ve employed and then open up to a group discussion and Q&A.
