What is PTA and how do I join? PTA - Parent Teacher Association - is an association of parents, teachers, and administrators who work together to sponsor programs benefiting the children of a school. Membership in PTA is open to anyone who believes in PTA's mission. When you join your school's PTA, you have a vote in deciding what programs your school's PTA will sponsor. You also become a member of the National and Missouri PTA's, whose collective voice of 6 million strong advocates for a quality education and nurturing environment for every child. Membership information will be available at your school's back-to-school event, and we encourage you to join. When you get involved with PTA, the child who benefits most is your own!
