Description: A computer program, called WinGen (Han, 2006) was developed to generate dichotomous and polytomous item response data for several IRT models and for many conditions that arise in practice. Although many IRT model simulation software programs have been developed, most of them were designed for intentionally narrow purposes since they were not publicly shared programs. WinGen is more general and more user friendly than many of the IRT simulation programs available today. WinGen is easy to use with an intuitive, user-friendly interface while providing very strong research tools and performance at the same time. Thus, WinGen should be useful for researchers who want to do simulation research, and students who are eager to learn more about IRT.
