Trade School is an informal learning exchange located in New York City where people can take classes and teach skills in exchange for other services or goods. It aims to demonstrate that people are interested in supporting one another and that value is subjective. Classes cover a range of practical and theoretical topics. Trade School has been invited to present at universities and museums. It is organized and run by teachers, students, and volunteers. It started in 2010 as a pop-up event and now operates for longer periods through fundraising and an annual membership model.
