When is EQAO 2026 Grade 9? The Grade 9 EQAO mathematics assessment <\/a>is written in two windows each school year: a winter window in January 2026 for students who take MTH1W in Semester 1, and a spring window in June 2026 for students in Semester 2 or full-year courses. Your child’s school chooses the exact day within the relevant window, so the precise date depends on which semester your child takes Grade 9 math. This guide gives you the full date picture, explains how the windows work, and shows you how to use the time before the assessment with grade 9 EQAO practice and the official EQAO sample test grade 9 so your child walks in confident.<\/p>\n\n\n\n

When is EQAO 2026 Grade 9? (Quick answer)<\/h2>\n\n\n\n

The Grade 9 EQAO is written during two testing windows<\/strong> in the 2025\/2026 school year, and which one your child writes in depends on when they take the MTH1W course.<\/p>\n\n\n\n

The single most important thing to know: schools choose the specific date within the window<\/strong>, so two students in different schools \u2014 or even different classes \u2014 might write on different days. Your child’s math teacher will confirm the exact date a few weeks beforehand.<\/p>\n\n\n\n

How the EQAO Grade 9 testing windows work<\/h2>\n\n\n\n

Unlike the Grade 3 and Grade 6 EQAO assessments \u2014 which are written once a year in late spring \u2014 the Grade 9 EQAO runs twice a year<\/strong> because the MTH1W course is offered in both semesters.<\/p>\n\n\n\n

Why there are two windows<\/h3>\n\n\n\n

Grade 9 math (MTH1W) is a semester-long course in most Ontario high schools. Students who take it in the first semester finish in January, so they write the EQAO in the January window. Students who take it in the second semester finish in June and write in the June window. Schools running full-year math write in June.<\/p>\n\n\n\n

This is different from elementary EQAO, where every student is in the same grade-long curriculum and writes at the same time of year.<\/p>\n\n\n\n

How schools choose the exact date<\/h3>\n\n\n\n

EQAO publishes a multi-week window for each session. Within that window, each school chooses specific days that fit its timetable, computer lab availability, and exam schedule. This is why there’s no single province-wide “EQAO Grade 9 day.”<\/p>\n\n\n\n

The assessment is usually written close to the end of the course \u2014 in the last few weeks of the semester \u2014 so the material is fresh and students have covered the full curriculum.<\/p>\n\n\n\n
