the (not so) hidden connection between neurodivergence and school avoidance in girls

I went looking for something else entirely (some other school avoidance rabbit hole, I don't even remember which one anymore, they all start to blur together after a while) when I found the number that actually stopped me. In one large study of children experiencing significant school distress, 92% were neurodivergent, and among the kids who had stopped attending school altogether, the figure was 95.7%. I read that twice, then a third time just to rule out the possibility that I'd forgotten how percentages work, which at 11pm felt like a real possibility. If your daughter is struggling to get to school and neurodivergence hasn't come up yet in any of the conversations you're having about it, I think it's worth raising, and I say that as someone who spent an embarrassingly long time assuming this didn't apply to us.

Neurodivergence is the umbrella term for things like autism, ADHD, dyslexia and sensory processing differences, conditions that overlap more than I'd realised and that, in girls especially, tend to look nothing like what I'd pictured, which is probably why it took me this long to even consider it. What got me, reading through study after study (yes, I became one of those people, the kind with fourteen browser tabs open and a slightly unhinged look by 1am), was learning that the diagnostic criteria for both autism and ADHD were built mostly by observing boys and tested mostly on boys, which is the kind of glaring oversight you only really notice once you're the one living downstream of it, and means a lot of girls with the exact same underlying wiring as the boys who do get diagnosed have spent years being missed, misread, or sent home with a shrug and a suggestion to try a bit harder. I know that shrug. I've sat across from it. I may have also, on at least one occasion, given a milder version of that exact shrug to myself in the mirror, so I'm not claiming any moral high ground here.

The thing I had to learn about before any of this started making sense was masking, a word I'd vaguely heard before and confidently assumed I understood, which tells you something about how much actual research I'd done up to that point.

Masking, sometimes called camouflaging, is what happens when a neurodivergent person works hard to hide or smooth over their natural responses so they read as neurotypical, and from what I've read it amounts to a full time, almost entirely invisible job, the kind that doesn't show up on a resume and definitely doesn't come with benefits: watching other people closely and copying their cues, rehearsing conversations before they happen, tracking her own facial expression in real time, holding still when her body wants to move, forcing eye contact that doesn't come naturally, running a constant internal check on whether she's doing the interaction correctly, all of it happening at once and on top of whatever the actual schoolwork and the actual social landmines of the day are already asking of her, which when you list it out like that makes me want to go lie down on her behalf. Girls seem to do more of this than boys, partly because there's so much pressure specifically on girls to appear friendly and easygoing and emotionally available (a pressure I am also, for the record, intimately familiar with, despite being decades past the age where anyone is checking), and partly because girls tend to start observing and copying social behaviour earlier in life, which means the masking can become so automatic, so early, that even she may never have registered it as effort.

What this produces, from the outside, is a kid who looks like she's doing fine: she has friends, or seems to, her grades are decent, she's not causing problems, teachers call her quiet and sweet and maybe a little sensitive, and nobody flags her for an assessment because there's nothing obviously wrong to flag, which is its own kind of cruelty when you think about it, being so good at hiding the problem that nobody thinks to look for one. What nobody sees is what happens once she's home. I hadn't fully understood, until I read about this, just how much effort it takes to hold a mask in place for an entire school day, something people have described as performing on a stage for every waking hour and never once getting to just be, and that kind of exhaustion is real and physical and cumulative, it doesn't just shake off overnight, and at some point, for a lot of these girls, the body simply stops being willing to go back and do it again, which from the outside can look like laziness or drama or a teenager being difficult for sport, and which I am embarrassed to admit I have, in weaker moments, also wondered about.

School itself, when you actually stop and look at it, is a genuinely strange thing to ask any kid to sit through all day, let alone a kid managing all of this on top of it: the noise in hallways and cafeterias, the unpredictability of who's friends with who this week, the expectation that you'll concentrate across several different subjects on a schedule you have no say in, the fluorescent lights, the constant switching between completely different demands with barely a breath in between, and if you described this exact arrangement to an adult and asked them to do it five days a week for thirteen years, you would, I suspect, be reported to someone. For a neurotypical kid that's a lot but it's manageable. For a kid who's also maintaining a mask the whole time, it's something closer to an ordeal, and the part that took me longest to understand, possibly because I didn't want to, is that the distress doesn't necessarily show up there. It shows up later, at home, in the evening, at the door the next morning, which means the school genuinely may not see it and may not entirely believe you when you describe it, and there's a very particular kind of maddening in trying to explain something you live with every single day to someone who's looking at you like you might be exaggerating, possibly for attention, possibly for fun, as though this is a hobby I've taken up.

There's a term, apparently, for a kid who holds it together all day and then falls apart the moment she's home: after school restraint collapse, and it's common enough in neurodivergent kids that I wish someone had just handed me this phrase years ago instead of leaving me to workshop my own increasingly creative theories about what was going on (a phase, a personality clash with a specific teacher, possibly just teenagers being teenagers, none of which, it turns out, were it). The meltdown at the front door isn't manipulation and it isn't drama, it's a kid decompressing from an enormous expenditure of effort that her school probably never witnessed and might not fully credit, which puts you, the parent, in the strange position of trying to describe a daily reality to people who weren't there for any of it, while also quietly wondering if you're the unreliable narrator of your own life, which is a fun feeling to sit with at 7pm on a Tuesday.

The statistics on how late girls tend to get diagnosed are worth sitting with for a minute, because they surprised me more than I expected, and not in a good way. Autistic girls are typically diagnosed years later than autistic boys, and plenty of autistic women don't get a diagnosis until their twenties or thirties or later, often after years of being told it's anxiety, or depression, or borderline personality disorder, and one study I came across found that 15% of patients at a clinic for borderline personality disorder actually met the criteria for autism, a statistic I have now repeated in at least three separate conversations because I genuinely cannot get over it. The pattern, as far as I can tell, goes something like this: a girl masks successfully for years, quietly burning through reserves she doesn't know she's spending, gets to middle or high school where the social complexity jumps and the demands on executive function jump with it, and the strategies that got her through elementary school just stop working. Her mental health starts to fray. And by the time anyone's paying attention, the presenting problem is anxiety or depression or school avoidance, and the neurodivergence underneath it, still undiagnosed, is invisible, so whatever help she gets is aimed at the anxiety without ever touching what's actually driving it, and you're left trying to solve a puzzle that's missing half its pieces while everyone keeps confidently handing you pieces from a completely different puzzle.

ADHD deserves its own mention here because it tends to show up so differently in girls, less hyperactive and more inattentive, which means it doesn't look like a kid bouncing off the walls, it looks like a kid who's quietly drifting, daydreaming, losing things, forgetting instructions, struggling to start a task or struggling to stop one, none of which tends to get anyone referred for an assessment. What it tends to get instead is a kid told to try harder and pay closer attention, which, having tried this exact advice on a number of unrelated personal failings of my own, I can report does not actually work, and never has, for anyone, in the history of advice. I can only imagine how exhausting it must be to live inside undiagnosed ADHD as a girl, doing active, effortful work for things that come automatically to everyone else, all day, every day, with none of it visible from the outside, until she comes home completely wrung out and, eventually, can't make herself go back.

None of this means your daughter's school avoidance is definitely tangled up with neurodivergence, or that she needs a formal diagnosis before anyone can help her, and I'll admit I still don't fully know where the line is for us. Some days I'm certain. Other days I think I'm just a tired woman who has read too many studies and is pattern matching her way toward a conclusion that feels more manageable than the alternative. But if the usual approaches keep stalling, the incentives, the firm talks, the gradual return plans, it might be worth wondering out loud whether there's something neurological going on that nobody's named yet, and worth asking that question of someone who actually knows what this looks like in girls specifically, which turns out to be a smaller list of people than I expected and, in my experience, a longer waitlist than seems legally permissible.

A few things I've started asking myself, for what it's worth, somewhere between googling and the things I probably shouldn't google at midnight: does she fall apart at home in ways that don't match anything the school describes? Does she struggle more than seems reasonable with noise, crowds, certain textures, clothes that don't feel right? Have people called her highly sensitive, or intense? Does she have interests she goes back to again and again and knows in incredible depth? Do transitions or changes to routine throw her more than they seem to throw other kids? Has a teacher ever called her gifted but underperforming, or bright but not working to her potential, a sentence I've heard described by more than one parent of an undiagnosed neurodivergent girl, usually in the exact same flat, exhausted tone, like we're all reciting lines from a play none of us auditioned for.

None of this is diagnostic, and I am, I cannot stress enough, not a doctor, just a parent with wifi and an unreasonable amount of free time at 11pm. It's just a handful of threads I found worth pulling on. And if you're reading this with that particular feeling of quiet recognition, the sense that this sounds a lot like your daughter, or maybe even a lot like you, that feeling is probably worth paying attention to, even if, like me, you spend a fair amount of time wondering whether you're onto something real or just tired enough to start seeing patterns in the carpet.

further reading: the Autistic Girls Network (autisticgirlsnetwork.org) is where a lot of my late nights eventually led, and it has more detailed, accessible material on masking, late diagnosis and how autism and ADHD tend to show up in girls, if any of this raised questions you didn't have an hour ago.
