The Education Quality and Accountability Office (EQAO) is an independent agency in Ontario, Canada that assesses student learning in public schools. It conducts standardized tests for students in Grades 3, 6, 9, and 10 to measure their skills in subjects like mathematics and language arts. The results help schools, parents, and the government understand how well students are performing. EQAO's assessments aim to provide valuable data that can improve education quality across the province. The tests are designed to be fair and reflect the curriculum, ensuring that all students have an equal opportunity to succeed.
