ASC’s expertise in computerized adaptive testing (CAT) is recognized around the world. Back in 2008, our co-founder was asked to contribute to an Education Week article about the topic. CAT was seeing a significant growth in the US K-12 market at the time, so it was a timely piece. Here’s part of the article:
In essence, “each student gets questions that are appropriate just for them,” said David J. Weiss, a professor of psychology at the University of Minnesota-Twin Cities and an expert on computer-adaptive assessments. “[In a fixed-form test], low-ability students are going to get questions that are too difficult, and they’re going to be frustrated,” he said. “[With an adaptive test], everybody will be equally challenged.”
In addition to shortening the length of the test, the approach creates a fairer psychological test-taking environment for each student, said Mr. Weiss, who has studied computer-adaptive tests since the 1970s.
