Article 77 of the Child and Youth Welfare Code provides that every elementary and secondary school shall organize a parents-teacher association for the purpose of providing a forum for the discussion of problems and their solutions, relating to the total school program, and for insuring the full cooperation of parents in the efficient implementation of such program. All parents who have children enrolled in a school are encouraged to be active members of its PTA, and to comply with whatever obligations and responsibilities such membership entails.
