the post-covid rise in school avoidance: what the data actually shows

Before my daughter stopped going to school, I had a vague sense that this kind of thing happened to some kids, somewhere, occasionally. I did not have any sense that it was happening at a scale significant enough to have its own research literature, its own clinical terminology, or its own entry in a BMJ journal article with the phrase "perfect storm" in the title. I do now, obviously, but the learning curve was steeper than it needed to be.

Here is what the data actually shows, because it's more striking than most people realise, and also because understanding it has a specific, useful effect on the particular brand of isolation that tends to come with this experience.

The numbers

Before the pandemic, roughly 15 percent of US students were chronically absent, defined as missing at least 10 percent of the school year, around 18 days. By 2022, that number had nearly doubled to 28 percent. It has since come down somewhat, to around 23.5 percent in 2024 according to the American Enterprise Institute's national tracking data, but no state has returned to pre-pandemic levels. In roughly half of urban school districts, more than 30 percent of students were chronically absent in the 2024-25 school year. District leaders now rank chronic absenteeism as one of their top three pressing challenges, on par with math and reading achievement, which is a sentence that would have been surprising five years ago.

These are not all school avoidance cases in the clinical sense. Chronic absenteeism includes students absent for any reason. But the trend line for emotionally based school avoidance, the kind driven by anxiety rather than logistics, has followed the same trajectory, and researchers who study it have been fairly direct about the connection. A 2024 paper in BMJ Mental Health described the overlap between rising post-pandemic absenteeism and rising EBSA as a "perfect storm," driven by school closures disrupting attachment to the school environment, pandemic anxiety that was never fully resolved, and a mental health system that was already stretched thin before any of this started.

Why girls specifically

This is the part that tends to get buried in the broader absenteeism conversation, and it's the part most relevant to families like ours. Multiple studies published since 2022 have found that older adolescent girls experienced a greater increase in anxiety symptoms than their male peers during and after the pandemic, and that those symptoms have been slower to resolve. One large review found clinically significant anxiety symptoms nearly doubling in young people overall, from around 12 percent pre-pandemic to over 20 percent post-pandemic. Among girls, social anxiety in particular increased and has remained elevated, which matters specifically because social anxiety is one of the most common drivers of school avoidance in adolescent girls.

The mechanism isn't complicated once you see it. Pandemic school closures removed the social environment entirely for a sustained period, during exactly the developmental years when girls are most sensitive to social threat and social comparison. When schools reopened, the environment they returned to wasn't the same one they'd left, and the anxiety that had developed in the gap didn't simply resolve because the buildings were open again.

What this means practically

None of the numbers make any individual family's experience easier. But they do change the frame, which matters more than it might sound. School avoidance is not a parenting failure that happened to a handful of unlucky families. It is a documented, research-confirmed consequence of a period that disrupted the social and emotional development of an entire generation of young people, with a measurable and persistent effect on girls in particular. The school system is still catching up to that reality, which is part of why the support on offer can feel so inconsistent. The research has moved faster than the institutional response, as it almost always does.

Understanding that doesn't fix anything on a Tuesday morning. But it does mean this isn't something that happened to your child and nobody else's, and that's a different thing to be carrying around than the alternative.
