This article describes a four-week congressional committee simulation implemented in upper level courses on Congress and the Legislative process at two liberal arts colleges. We find that the students participating in the simulation possessed high levels of political knowledge and confidence in their political skills prior to the simulation. An analysis of pre- and posttest surveys indicates that students experienced significant increases in their self-assessed understanding of the political process, the ability to persuade others to support political positions, and the ability to work with diverse groups to accomplish political goals. Additionally, students without prior internship experience reported notable and statistically significant gains in self-assessed political skills and efficacy. These findings suggest that, for students who cannot participate in an internship, participating in a simulation may generate many of the same benefits.
