A screening license is required for all screenings organized outside of one’s home - this is true whether or not you charge for tickets, or are a for-profit, non-profit organization or school. However, license fees vary by location(s), type of organization and how many times you plan the screen the film.
You may select the license that is right for you from the following links:
When you buy, rent, or borrow any type of audiovisual work made by someone else (like the team behind Girl Rising!), you obtain only the copy of the content itself, and not the copyright to the movie. You certainly are free to watch the movie yourself or with your personal network in a private setting, but, beyond that, your rights are limited by law. When you purchase a screening license you are buying the rights to publicly screen the film in a designated location.
As an independent screening host, you are eligible for a public performance license which is considerably cheaper than what a commercial cinema must pay to show a film. Even if the cost seems unreasonable, please keep in mind that this is a standard practice for documentary films.
