A campus can only plan for the students it knows are there. A study published this year says colleges and universities have been badly underestimating one group in particular, and the reason has less to do with who enrols than with who is ever counted.
Researchers led by Bradley Cox at Michigan State University set out to answer a question that sounds simple and turns out not to be: how many autistic students are actually in higher education? Their paper, published in the journal Autism in Adulthood in March 2026, worked through 731 publications, 16 common student surveys, and six federal datasets, then synthesized the usable data from 14 of them, to build the first national estimate of its kind. The answer they landed on is a range, and it is a wide one.
What the study found
The researchers estimate that between 135,400 and 286,254 autistic undergraduates are currently attending college in the United States. To get there, they worked through three separate questions.
First, how many autistic high school students go on to post-secondary at all. Their best estimate is 42.9 to 47.0 per cent, close to half, and far higher than the older picture of college as mostly closed to autistic students. Second, what share of students already registered with a campus disability services office are autistic: 2.8 to 4.0 per cent. Third, what share of all undergraduates are autistic: somewhere from 0.3 to 4.7 per cent, a spread that shows how uncertain the underlying data still is.
The authors are careful about that uncertainty. As they put it, “current data do not allow a single number,” so they offer ranges rather than a headline figure. Even so, their point stands: the population is several times larger than campuses have assumed, and, in Cox’s words to Inside Higher Ed, “it’s hard to serve a population you don’t know is even there, because autism is an identity that isn’t always apparent, isn’t always visible.”
Why the count is almost certainly low
The gap is not mainly about enrolment. It is about disclosure.
Colleges tend to count autistic students through one door: the disability services office, and only for students who register there. That leaves out anyone who has a diagnosis but does not disclose it, anyone who registers under a different qualifying condition, and anyone who never asks for accommodations at all. Cox told Inside Higher Ed that many students diagnosed before college “don’t actually report that identity or seek academic accommodations through a disability service office,” and that even those who do “often don’t feel like they’re the ones that are most necessary or important or valuable.”
That matters because the whole support system is built to activate only when a student comes forward. A student who stays quiet, for privacy, for fear of stigma, or because the process looks exhausting, is invisible to the people whose job is to help. The count and the support run through the same narrow gate.
What Canada knows about its own campuses
The Cox study is American, and the authors say plainly that their estimates “may not apply to higher education in other countries.” Canada has no comparable national count of autistic post-secondary students. What it does have is a map of how thin the specific supports are.
In a 2021 study in Research in Autism Spectrum Disorders, a team led by Megan Ames scanned the websites of Canada’s publicly funded post-secondary institutions for autism-specific supports, things like transition programs, peer mentoring, and social groups. Their finding: “Of the 258 publicly-funded postsecondary institutions in Canada, only 15 institutions (6%) had at least one support.” Among those 15, the most common offering was simply information on the institution’s website (67 per cent), followed by transition-to-university support (47 per cent) and social groups (33 per cent). Universities and institutions in Ontario and British Columbia held a disproportionate share.
Six per cent is not a measure of how many autistic students are enrolled in Canada. It is a measure of how few campuses have built anything designed specifically for them. The rest rely on the general disability accommodation system, which brings us to the part a student can actually use.
The system runs on the student coming forward
In Canada, post-secondary education is a provincial responsibility, and the right to accommodation sits in provincial human rights law rather than one national statute. The shape of it is consistent across the country, though, and Ontario states it clearly. The Ontario Human Rights Commission puts it this way: “Education providers have a duty to accommodate students with disabilities up to the point of undue hardship.”
That duty is real, and it is strong. But it is also, in the Commission’s words, “a shared responsibility.” The institution must have “appropriate, effective and dignified accommodation processes” in place. The student’s part is to start the process: a student “is required to advise the education provider of the need for accommodation, participate in discussions regarding possible accommodation solutions,” and work with the office over time.
In practice that means two things. Accommodation is individualized, worked out between the student and the disability services office rather than handed down as a fixed package. And it does not begin until the student registers and, in most cases, provides documentation of a disability. This is the same mechanism the Cox study describes: support is available, but only to students who identify themselves and ask. A diagnosis on its own does nothing until it is brought through the door.
What a student can ask for
If you are an autistic student, or heading to post-secondary soon, the practical move is to treat the disability services office as a starting point rather than a last resort, and to register early, before a crisis, when there is time to set things up.
Accommodation is individual, so there is no fixed list. But these are the kinds of supports students commonly discuss with a disability office, and any of them is worth raising:
Exam arrangements, such as extended time or a lower-distraction testing space. Note-taking support or permission to record lectures. Advance access to slides, readings, or a course outline so the term holds fewer surprises. Flexibility around attendance or participation formats where a course allows it. Alternative formats for materials. And a single, named point of contact in the office so you are not re-explaining yourself to a new person each time.
You do not have to know which of these you need before you go in. Naming the difficulty, the group project, the timed exam, the lecture you cannot process in real time, is enough to open the conversation. The office’s job is to work the solution out with you.
We are describing how the system works, not giving legal or clinical advice. Programs, documentation rules, and timelines differ by province and by institution, so the office at your own school, and your provincial human rights body, are the places to confirm what applies to you.
The larger point from this year’s research is worth holding onto. The students are there, in far greater numbers than campuses have counted, and the reason they go uncounted is the same reason some go unsupported: the system waits for them to speak first. Knowing that is knowing where the door is.
Frequently asked questions
How many autistic students are in higher education in the United States?
A study led by Bradley Cox at Michigan State University, published in Autism in Adulthood in March 2026, estimates that between 135,400 and 286,254 autistic undergraduates are currently attending college in the United States. The authors say “current data do not allow a single number,” so they offer ranges. They estimate that 42.9 to 47.0 per cent of autistic high school students go on to post-secondary, and that 2.8 to 4.0 per cent of students registered with campus disability services offices are autistic.
Why are autistic students likely undercounted on campus?
Colleges tend to count autistic students through one door, the disability services office, and only for students who register there. That leaves out anyone who has a diagnosis but does not disclose it, anyone who registers under a different qualifying condition, and anyone who never asks for accommodations at all. The support system also activates only when a student comes forward, so a student who stays quiet is invisible to the people whose job is to help.
Does Canada count autistic post-secondary students?
Canada has no comparable national count of autistic post-secondary students, and the authors of the American study say their estimates “may not apply to higher education in other countries.” A 2021 study in Research in Autism Spectrum Disorders scanned the websites of Canada’s 258 publicly funded post-secondary institutions and found that only 15 of them, 6 per cent, had at least one autism-specific support. That figure measures how few campuses have built anything designed specifically for autistic students, not how many are enrolled.
Do Canadian colleges and universities have a duty to accommodate autistic students?
Post-secondary education is a provincial responsibility, and the right to accommodation sits in provincial human rights law. The Ontario Human Rights Commission says education providers have a duty to accommodate students with disabilities up to the point of undue hardship, and that this is a shared responsibility. The student’s part is to advise the education provider of the need for accommodation and take part in discussions about possible solutions. Programs, documentation rules and timelines differ by province and by institution, so confirm what applies to you with your own school’s office and your provincial human rights body.
What can an autistic student ask a disability services office for?
Accommodation is individual, so there is no fixed list, but students commonly discuss exam arrangements such as extended time or a lower-distraction testing space, note-taking support or permission to record lectures, advance access to slides and readings, flexibility around attendance or participation formats where a course allows it, alternative formats for materials, and a single named point of contact in the office. You do not have to know which of these you need before you go in, because naming the difficulty is enough to open the conversation. It helps to register early, before a crisis, when there is time to set things up.
