In higher education, the demand for robust assessment systems has never been higher. We recently conducted a one-week graduate-level course on classic test theory (CTT) and item response theory (IRT) for STEM experts. CTT is a conventional statistical framework. It underpins conventional student testing that assists test developers to judge the general quality and their tests and questions. IRT is a more modern statistical framework, which enables test developers to implement cutting-edge and highly reliable assessment systems to monitor student progress.
