The Test Response Function (TRF) in item response theory (IRT) is a mathematical function that describes the relationship between the latent trait that a test is measuring, which psychometricians call theta (θ), and the predicted raw score on the test in a traditional notion (percentage/proportion/number correct). An important concept from IRT, it provides a way […]

Classical Test Theory and Item Response Theory (CTT & IRT) are the two primary psychometric paradigms. That is, they are mathematical approaches to how tests are analyzed and scored. They differ quite substantially in substance and complexity, even though they both nominally do the same thing, which is statistically analyze test data to ensure reliability […]
The two terms Norm-Referenced and Criterion-Referenced are commonly used to describe tests, exams, and assessments. They are often some of the first concepts learned when studying assessment and psychometrics. Norm-referenced means that we are referencing how your score compares to other people. Criterion-referenced means that we are referencing how your score compares to a criterion such […]
The item-total point-biserial correlation is a common psychometric index regarding the quality of a test item, namely how well it differentiates between examinees with high vs low ability. What is item discrimination? While the word “discrimination” has a negative connotation, it is actually a really good thing for an item to have. It means that […]
The California Department of Human Resources (CalHR, calhr.ca.gov/) has selected Assessment Systems Corporation (ASC, assess.com) as its vendor for an online assessment platform.

Online proctoring software refers to platforms that proctor educational or professional assessments (exams or tests) when the proctor is not in the same room as the examinee. This means that it is done with a video stream or recording using a webcam and sometimes an additional device, which are monitored by a human and/or AI. […]
Nathan Thompson, Ph.D., was recently invited to talk about ASC and the future of educational assessment on the Ednorth EdTech Podcast. EdNorth is an association dedicated to continuing the long history of innovation in educational technology that has been rooted in the Twin Cities of Minnesota (Minneapolis / Saint Paul).
