PTA is the largest volunteer child advocacy organization in the nation; PTA  reminds our country of its continued obligation to all children. Created as a  partnership among parents, educators, students, and other individuals, the PTA  actively works in schools and communities to improve the lives of every child.  PTA is a not-for-profit association with nearly 6.5 million members who work in  26,000 local units in all 50 states, the District of Columbia, the U.S. Virgin Islands, and in Department of Defense schools in Europe and the Pacific.  Becoming a PTA member means you’re adding your voice to those working to make a  difference in children’s lives. A PTSA is a PTA that includes and encourages student participation.
