Methodology
The analysis uses the 2024–25 EQAO English-language school-level files for Grades 3, 6 and 9, along with Grade 10 literacy results for first-time eligible students.
The data were limited to English-language HDSB public schools using the following filters: BoardName = Halton DSB, OrgType = S and Language = en.
Results were weighted by the number of participating students, not by school. For each measure, the number of students who met the provincial standard was divided by the total number who fully participated. For Grade 10 literacy, the calculation uses first-time eligible students who successfully completed the assessment.
A school without a reportable group for a particular measure was excluded from that calculation. It was not given a score of zero.
Limitations
These results show differences in published EQAO outcomes, but they do not explain what caused them. Factors such as staffing, school capacity, student mobility, special education needs, attendance and access to programs may all affect the results.
The comparison also covers different geographic areas. The Milton group includes schools in one trustee area, while the Oakville and Burlington groups include all reportable English-language HDSB public schools in those municipalities.
