The mission of the New York City Student Union is:
to act as a powerful, collective voice for New York City students that can defend the rights we are so often deprived of due to lack of organization; to give students a voice in the decisions made about our own education, and to allow students to work cooperatively with school officials, department of education officials and public officials to find solutions to the problems that plague the lives of city youth; to provide communication between students from all ends of the city, and to ensure that students are able to make the most of the broad array of educational and social opportunities we are offered.
