Beginning Tuesday, May 23, grade 3 and 6 students will begin EQAO assessments of reading, writing and mathematics. Grade 9 students will complete their assessment of mathematics, beginning on Monday, June 5. Please check with your individual school for exact assessment dates.

The Education Quality and Accountability Office (EQAO) is an independent provincial agency, funded by the Government of Ontario, that develops and oversees reading, writing and mathematics tests that all Ontario students must take in grades 3, 6, 9 and 10. EQAO’s mandate is to conduct province-wide tests at key points in every student’s education and report the results to educators, parents and the public. EQAO measures students’ achievement in reading, writing and mathematics in relation to Ontario Curriculum expectations.

EQAO assesses students throughout their school career:

  • Grade 3 assessment of reading, writing and mathematics
  • Grade 6 assessment of reading, writing and mathematics
  • Grade 9 assessment of mathematics (all students working toward a credit in Grade 9 academic or applied mathematics are required to participate)
  • Grade 10 Ontario Secondary School Literacy Test (OSSLT) – successful completion of the test is one of the requirements students must meet to earn an Ontario Secondary School Diploma
