Research shows that chronic absenteeism—defined as missing school frequently over a long period—among Canadian kindergarten students rose sharply after the start of the COVID-19 pandemic. Before the pandemic, about 17.7% of kindergarten students were chronically absent, but this number more than doubled to 41.3% afterward. The study, which analyzed data from over 500,000 children in eight provinces, found that the increase was most significant in Ontario, while British Columbia saw the smallest rise. These differences may be connected to how each province handled public health measures and implemented school policies during the pandemic. One unexpected finding from the study was that children who were chronically absent after the pandemic were less likely to be considered developmentally vulnerable compared to those who missed school frequently before the pandemic. Developmental vulnerability refers to delays in key areas like communication, physical development, and problem-solving. Researchers suggest that this shift might be due to changes in the types of children who were chronically absent. After the pandemic, a larger share of these children came from higher socioeconomic status (SES) neighborhoods, where children generally have better developmental outcomes. The researchers believe that the change in the composition of the chronically absent group, rather than a decrease in the negative effects of absenteeism, may explain this finding. Another possible reason is the increased availability of online learning and other educational resources at home, which may have helped some children continue learning even when they were not physically present in school. Families with more resources may also have been better equipped to support their children's learning from home. The study emphasizes the need for more research to understand the reasons behind school absences and their impact on children’s learning and development. It also calls for the creation of policies that aim to reduce missed school days while helping children and families who face challenges in attending school regularly.
