Inspiring The Improvisor


More ITI

ITI logoITI stands for: The International Theatresports™ Institute, but we are much more than just ‘Theatresports’. We are dedicated to supporting, developing, connecting and promoting the growing community of improvisers who work with Keith Johnstone’s improvisational techniques and formats. In 1998 the ITI was set up as the official worldwide management of the Production Rights to Keith Johnstone’s formats Theatresports™, Maestro Theatre™, and Gorilla Theatre™.

Our membership numbers over 90 companies, schools and Universities from 22 countries on 6 continents. The formats are performed in 17 different languages.

Who owns the ITI?

The ITI is a not-for-profit organisation that was created by Keith Johnstone to manage the Production Rights for Theatresports™, Maestro Theatre™, and Gorilla Theatre™. No one owns the ITI. Your membership and donations support the community, and enable Member Perks.

How does it operate?

The ITI is managed by our Office Administrator, a Board of Directors comprised of nine elected Regional Representatives, and a number of Advisory Board members. The Office Administrator looks after all administrative and office duties, helps implement initiatives decided on by the Board of Directors and manages the day to day operations of the organization.


The Regional Representatives are volunteers elected by the members of their region. They are the voice of the Membership at the Board level who can field questions, concerns, ideas for improvements, or whatever support the Membership needs. Regional Representatives speak on their member’s behalf and their primary purpose is to serve the members in their region. Regional Representatives have no authority on memberships, licenses and artistic policy.

The Advisory Board are volunteers who ensure the By-laws and Articles of Association are followed to secure the longevity of the ITI. Together, the Office Staff and Board of Directors work to inspire the community through communication, information, professional development, Festivals, and policies that represent what is happening in each Region.
