For most people with ADHD symptoms and impairments continue into adolescence and adulthood. These impairments can significantly impact a student’s functioning in the post-secondary setting. The good news is that many more students with ADHD are now able to qualify for entry into post-secondary learning institutions, due to the advances in awareness, diagnostic procedures and the care and support of children and adolescents with ADHD. However, since impairments continue, most will still require appropriate services and learning accommodations be put in place in academic settings. Post-secondary students with ADHD will exhibit marked functional impairments in organizational and time management skills, note taking; reading comprehension; written expression; and keeping track of materials, despite their success in gaining entry to post-secondary institutions. These impairments often result in incomplete and late assignments, which in turn frequently lead to students with ADHD becoming easily over-whelmed and anxious. Some students are able to function well enough in elementary or even high school when supports are in place and academic loads were lighter, but once challenged to a greater degree their impairments become evident. These students will need to be assessed and diagnosed once in the post-secondary education setting.

While students with ADHD may present with significant difficulties in executive function, memory, learning, and speed of information processing, ADHD is not medically categorized or recognized as a learning disability, but rather a mental health or neurodevelopmental disorder. However, it is imperative to note that without assistance many students with ADHD – not just those with a concurrent Learning Disability – are at high risk for academic underachievement or failure despite having average or above average intellectual abilities.


Unfortunately ADHD and its resulting impairments continue to be inadequately understood by post-secondary institutions. This has resulted in some of these institutions demanding that students with ADHD undergo unreasonable costly testing in order to be identified as having a disability. All current Clinical Practice Guidelines for ADHD (including the Canadian guidelines), as well as the DSM-5 diagnostic criteria for ADHD, require evidence that the symptoms impair social, academic, or occupational functioning. Thus, evidence of impairment is one of the required diagnostic criteria for ADHD.

However, a diagnosis of ADHD alone (even if it indicates impairment) is not sufficient for documenting impairment as required by Post-Secondary Education institutions, which require evidence that the person’s functional limitations impact academic performance. In addition, the Canadian government requires that impairment in post-secondary students be a permanent disability that impacts functioning in the post-secondary setting. Since persistent functional impairments such as poor organizational and time management skills, difficulty with note-taking, reading comprehension and written expression constitute a permanent disability, ADHD clearly qualifies as such.

Currently, there are no agreed-upon national or provincial standards for assessment and documentation practices to assure fair access to accommodations and services in post-secondary education for students with ADHD.  There is inequity across and within Canadian Provinces, with some post-secondary institutions requiring similar documentation for ADHD and for Learning Disabilities: that is, they require neuropsychological or psycho-educational testing to determine the severity of ADHD and to quantify the impact of ADHD on cognitive or academic functioning.

The demand that students entering post-secondary education require psychoeducational testing and reporting that indicates a disability is unreasonable or valid, since few if any of the tests used quantify accurately cognitive or academic impairments that caused by ADHD.

Since a detailed report by an ADHD medical expert would be required to meet Canadian government requirements and provide post-secondary institutions with the necessary information they require to understand the student’s unique impairments and need for accommodations, CADDAC has produced some guidelines and a tool to assist medical experts on how to write these reports.

This report should:

  • Identify the permanent disability and list specific impairments
  • Indicate how these impairments would negatively impact functioning of the student in the post-secondary academic setting
  • Link requested accommodations to existing impairments of the student
