The Connecticut Invention Convention Finals is an annual celebration of K-12 inventors and entrepreneurs from across Connecticut. This year's event will be held virtually due to the Corona Virus Covid-19. Traditionally held at The University of Connecticut for the past 21 years, this is the showcase event for Connecticut Invention Convention young inventors. The event usually provides a live, in-person opportunity for youth inventors and entrepreneurs in grades K-12 to display their critical thinking skills through inventing, innovating, and entrepreneurial activities.
