Study led by 91亚色 U tracks decade-long rise in high school absenteeism

As Ontario moves to make attendance and participation part of high school students' final marks, 91亚色 research offers context for what rising absenteeism may signal and why there may be no simple fix.

The study, co-authored by Faculty of Education's Robert Brown, adjunct professor, and Gillian Parekh, associate professor and Canada Research Chair in Inclusion, Disability and Education, along with collaborators from the Toronto District School Board (TDSB) and Wilfrid Laurier University, uses the 2011-12 academic year as a baseline to track absenteeism trends in TDSB schools through 2023-24.

One of the study's key findings complicates the common assumption that rising absenteeism is mainly a post-COVID issue. While student absence rates surged dramatically during and after the pandemic, the researchers found that roughly one-third of this increase was already underway before the pandemic.

"COVID took existing trends and put them on steroids," says Brown. "This isn't something just caused by COVID."

The study finds that absenteeism roughly doubled over the 12-year period, with increases evident across grades. Brown says attendance tends to be relatively high in kindergarten, stable through much of elementary school, then rises in senior elementary grades before accelerating in high school. More recent 2023-24 data show some decline in absence rates among early and mid-elementary students, but rates continued to climb across all secondary grades.
