PTA advocacy helps you, your child and all OES children because you will learn what you can do to positively impact students, families and schools, as well as education programs and services. PTA is the nation’s oldest and largest volunteer child advocacy association. For over 125 years, PTA members have been behind historic achievements like child labor laws, the federal school lunch program, and more. Your membership supports PTA advocacy at our school, in our local community, in our state and on Capitol Hill.
