This project will investigate the use of Moderated Nonlinear Factor Analysis (MNLFA) as a potential improvement upon existing vertical scaling methods that use the common item, nonequivalent group (CING) design. Vertical scales aim to capture growth across time by linking test forms appropriate for students of different ages, placing scores onto a common scale. This scale design is integral to several applications in education, ranging from the measurement of individual students' growth acro...
