How To Guide

Invent Iowa uses the Invention Convention U.S. Nationals rules and guidelines.

Local Invention Convention

Schools and groups are encouraged to organize local invention conventions to provide students with the opportunity to share their inventions and receive direct feedback. However, participation in a local convention is not a prerequisite for submitting an invention application to the State Invention Convention. The Belin-Blank Center does not host or sponsor local conventions. Individual students have the option to enter without going through a school program.
