The Ontario Public School Boards' Association (OPSBA) represents public district school boards and public school authorities across Ontario. The association ensures that the best interests of Ontario's students are considered by the Ministry of Education and other provincial ministries.

OPSBA trustee members and staff analyse, develop and evaluate education policies. The association lobbies the government for a fair and effective education system and promotes public education to parents, taxpayers, students, businesses, the community and the media.

OPSBA also provides a range of services and programs to the education system to enhance members and partners in the delivery of public education.
