A board of directors is a legally-designated decision-making body in a nonprofit, nongovernmental organization that is charged with establishing and maintaining an organization. They set the goals and objectives of the organization and maintain the authority to govern the organization throughout its existence.
Can youth participate in nonprofit boards of directors? It depends. In the United States the right for youth to create or participate in the boards of directors is made at the state level, so that what holds true in California may not be the same in Florida, and so forth.
In 2007 I co-authored a book with Youth On Board out of Boston called “15 Points To Successfully Involving Young People In Decision-Making.” In that book there is a table (pp 113-114) that provides a state-by-state analysis of the laws that effect youth involvement on boards. Eight of 50 US states disallow people under 18 from being on their boards of directors. In the other 42 states there is no specific age for directors specified in state law. Nine different states disallow young people from incorporating nonprofit organizations.
