ASC has been a game-changer in assessment and psychometrics since 1979.
Assessment Systems Corporation (aka ASC or Assessment Systems) was founded with the sole purpose of modernizing assessments to create improve educational and career opportunities.
David Weiss, Ph.D., and David Vale, Ph.D. – our founding fathers – were the pioneers of computerized adaptive testing (CAT) and the use of item response theory (IRT). They drove early research in the 1960s and 1970s on the use of AI in assessment and psychometrics, as part of the Department of Psychology at the University of Minnesota. ASC was founded to bring that technology to a wider range of organizations.
Assessment Systems Corporation has been a trusted provider in computerized testing since its inception. We were involved with the first research on computerized assessment in the 1960s and 1970s, and built the first publicly available software for adaptive testing and item response theory in the early 1980s.
Our team is dedicated to improving assessment. Of course, a large part of this is quality software with modern psychometric technology.
