Mixture IRT modeling allows the detection of latent classes and different item parameter profile patterns across latent classes. In Rasch mixture model estimation, latent classes are
assumed to follow a normal distribution with means constrained to be equal across latent classes for the model identification purpose. In the literature, this conventional constraint was
shown to be problematic in establishing a common scale and comparing item profile patterns across different latent classes. In this study, a simulation study was conducted to explore the
degree of recovery of class membership. Also, the class membership recovery of the conventional constraint approach was compared to the class-invariant item constraint approach. The results
show that the recovery of class membership has the similar recovery for both approaches. In addition, the consistency of class membership for two approaches is consistent with each
other. / A Thesis submitted to the Department of Educational Psychology and Learning Systems in partial fulfillment of the requirements for the degree of Master of
