Parent-teacher organizations
Parent-teacher organizations are volunteer groups that work to improve the education, health, and safety of children and youth in local communities. They encourage close cooperation between home and school to achieve this goal. Parent-Teacher Associations, called PTA's or PTO's (Parent-Teacher Organizations), are the most numerous and active of these groups in the United States. Other parent-teacher organizations include Home and School Associations, various local parent advisory committees, and school-based councils.
