2025-2026 EQAO Highlights
The provincial Education Quality and Accountability Office (EQAO) has released the 2025-2026 assessment results for Ontario schools. The Durham District School Board (DDSB) continues to demonstrate strong achievement in literacy across elementary grades and Ontario Secondary School Literacy Test (OSSLT). There are continued efforts to strengthen student achievement in mathematics.
Key Highlights
-
Strong literacy achievement across the system: 85% of Grade 6 students met provincial standards in Reading and 84% in Writing, while 73% of Grade 3 students met the provincial standard in Reading and 66% in Writing. The DDSB's OSSLT success rate remained strong at 86%.
-
Improvements in several assessments: Compared with the previous year, DDSB saw improvements in Grade 3 Writing and Grade 6 Reading, Writing and Mathematics. Literacy outcomes for multilingual language learners (MLLs) also improved in Grade 6 meeting the provincial standard with 61% in Reading and 59% in Writing.
-
Students with Individual Education Plans (IEPs): Students receiving special education supports demonstrated improvements in several assessments, including Grade 3 Reading, Writing and Mathematics, and Grade 6 Reading and Writing. These results reflect positive progress, while highlighting the importance of continued efforts to support student achievement.
-
Positive trends in French Immersion: Students in French Immersion continued to achieve strong results, with particularly high levels of success in Grade 6 at 94% in Reading and Writing, and improvements across other areas.
-
Mathematics remains a key area of focus: While Grade 6 Mathematics improved slightly to 48% and Grade 9 Mathematics remained stable at 58%, mathematics achievement continues to be an area for targeted support, particularly for multilingual language learners and students with IEPs.
-
Achievement gaps remain: While many student groups experienced success, results indicate continued opportunity to strengthen outcomes for multilingual language learners and students with IEPs across several areas, particularly in mathematics.
