Participating classes are encouraged to hold a showcase hearing for their Project Citizen. This format provides students with an opportunity to gain knowledge of how public policy is formulated. Some New Jersey schools participating in Project Citizen have been successful in having their projects become public policy. Classes are encouraged to enter their project and oral presentation in the yearly Project Citizen Statewide Portfolio Showcase. At the showcase individual school projects and oral presentations are shared with other schools and judged by panels of educators and public policymakers.

Assistance in the preparation of the portfolio and simulated public hearing can be provided by the New Jersey Center for Civic and Law Related Education. The project that earns first place is displayed in the New Jersey Statehouse and sent to be displayed at the National Project Citizen Portfolio Showcase held at the annual meeting of the National State Legislators.

The NJ Project Citizen Showcase is now open to high school as well as middle school classes.
