ASC has been a world leader in psychometrics and technology since the 1970s! Learn about our history, mission, and team of experts. Our Mission: To positively impact educational and career opportunities by facilitating the development and delivery of fair, valid, and reliable assessments. Founded out of the University of Minnesota, with a singular focus on improving assessment. ASC was founded out of the psychometrics PhD program at the University of Minnesota, the North Star State. 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). Their passion and commitment to re-inventing how we do educational and workforce assessment led to extensive funding from the US government as part of their groundbreaking research on IRT/CAT at the University of Minnesota in the 1970s.
