Can I use the same ADHD diagnosis letter for school and work?
Quick answer
Usually, yes. A diagnosis letter that names the diagnosis, describes your functional limitations and suggests accommodations in general terms can be given to both a school and an employer. The difference is how much each is entitled to see: an employer generally needs your limitations and needs rather than the diagnosis itself, while most post-secondary accessibility offices want the diagnosis named. Ask for a letter that covers all three elements, and keep a copy so it can be reused.

One letter usually serves both, because schools and employers ask for the same three things
A single letter works for both settings when it contains the three elements every accommodation process is built on: confirmation that a regulated clinician made a diagnosis, a description of how the condition limits you, and a statement of what would help. Finding Focus issues a standard diagnosis letter for $49, listed on the pricing page, and it is written to be reused rather than tied to one recipient. Whether a school or workplace accepts an online diagnosis at all is a separate question, answered on the acceptance page.
- The diagnosis and who made it. The clinician's name, designation and registration details, the date, and the criteria used (DSM-5-TR).
- Functional limitations. What the clinician documented about sustained attention, organisation, time management, working memory or follow-through, in plain language a non-clinician can act on.
- Recommended accommodations. Stated generally enough to apply in either setting: extended time on timed tasks, a quieter workspace, written instructions, breaks, or reduced distraction. The Canadian ADHD Practice Guidelines from CADDRA include accommodation templates that clinicians draw on for this section.
A letter with all three can be handed to a university accessibility office on Monday and a human resources contact on Tuesday. A letter that only confirms the diagnosis, with no functional detail, will often be sent back by both.
An employer is entitled to less of the letter than a school
The same letter serves both, but you are not obliged to show both the whole thing. Human rights law in every province Finding Focus serves requires employers to accommodate disability to the point of undue hardship, and the information they need to do that is about limitations and needs, not the medical label. Schools work differently, because accessibility offices generally register students on the basis of a documented disability and want the diagnosis named.
| Element | Employer | Post-secondary accessibility office | Elementary or secondary school |
|---|---|---|---|
| Diagnosis named | Not usually required; limitations are enough for most requests | Usually required | Usually required for a formal plan, such as an Individual Education Plan |
| Functional limitations | Required; this is what the accommodation is built on | Required | Required |
| Recommended accommodations | Helpful; the employer decides what is reasonable | Helpful; the office decides what is approved | Helpful; the school team decides |
| Clinician's credentials and registration | Expected | Expected, and some offices specify which professions they accept | Expected |
| Date and recency | Rarely specified | Often specified; check the office's documentation policy | Sometimes specified |
Because the employer column needs less, some people ask for two versions of the same letter: one with the diagnosis named for the school, and one that describes limitations and needs without the label for the employer. Both come from the same record and say the same thing about function. The workplace recognition page covers how much to disclose at work and when.
At work, the letter supports accommodation but is not a sick note, an EI certificate or a tax form
The most common mistake is expecting a diagnosis letter to do jobs that need a different document. Three come up repeatedly.
- Medical leave. An employer asking you to justify time off wants a note that says you are unable to work and for roughly how long. A diagnosis letter does not say that. Ask the treating clinician for a separate note if leave is what you need.
- Employment Insurance sickness benefits. Service Canada states that EI sickness benefits can provide up to 26 weeks of support at 55 per cent of earnings, to a weekly maximum of $729, and that you must obtain a medical certificate showing that you are unable to work for medical reasons and for approximately how long. That certificate is a specific document signed by an eligible professional, not a diagnosis letter.
- Disability Tax Credit. The Canada Revenue Agency requires Form T2201, certified by a medical practitioner, and assesses the effects of impairment rather than the diagnosis. A letter can inform the certifier but does not replace the form.
Both sides check who signed the letter, and schools are more likely to check when
A letter from Finding Focus is signed by a licensed nurse practitioner or clinician working with the clinic, and institutions in the provinces served generally accept documentation from a regulated health professional whose scope includes diagnosis. In Ontario, for example, nurse practitioners are registered with the College of Nurses of Ontario in the extended class under the Nursing Act, and the Nurse Practitioners' Association of Ontario describes their authority to formulate and communicate a diagnosis and to prescribe medications, including controlled drugs and substances. Each province's nursing regulator sets the equivalent scope, and an accessibility office that lists accepted professions will usually name nurse practitioners alongside physicians and psychologists; if a policy is silent, ask before you submit.
Recency is where schools and workplaces diverge. Employers rarely put a date limit on documentation, because the duty to accommodate is ongoing and they reassess as needs change. Post-secondary offices more often publish a policy on how recent documentation must be, especially for a first registration, and some distinguish between a diagnosis that can be older and a functional description that should be current. If your letter is a few years old and the school asks for something recent, a follow-up visit at Finding Focus, at $74.99 per check-in without membership, allows the clinician to update the functional description without repeating the assessment. The documentation page lists what the clinic can and cannot write.
Ask for a reusable letter, keep the original, and share only the version each recipient needs
A few practical choices make one letter go further.
- Tell the clinic when you request the letter that it will be used for both school and work, so the functional limitations and accommodations are written in setting-neutral language.
- Ask whether a version without the diagnosis named can be issued for the employer, if you prefer not to disclose the label at work.
- Keep a clean PDF and never send your only copy. Institutions keep what they receive; you should too.
- Check the recipient's documentation policy before submitting. If it asks for something the letter does not contain, such as test scores or a treatment history, that is a request for the fuller $99 healthcare-provider report rather than a second letter.
- When circumstances change, such as a new job or a new program, reuse the letter first and only request a new one if the recipient asks for updated content.
A letter describes your needs; it does not decide the outcome. Each employer and each school weighs the request against its own obligations and resources, and neither Finding Focus nor any clinician can promise a particular accommodation will be granted. If you are in crisis or thinking about harming yourself, call or text 9-8-8 or call 911; accommodation paperwork can wait, help should not.
Common questions
Related questions, answered
Name them, but generally. A clinician can recommend extended time, reduced distraction or written instructions because those follow from documented limitations. The school or employer then decides what is reasonable in its setting, and a letter that reads as a list of demands tends to get less traction than one that explains the limitation and suggests a remedy. Specific implementation is negotiated with the recipient, not written by the clinic.
Yes, on the same principle, although a youth assessment at Finding Focus is available only in select provinces and for ages 12 to 17. Secondary schools usually want the diagnosis named for a formal plan, while a part-time employer needs only limitations and needs. Parents often keep the full letter for the school and share a limitations-only summary with an employer.
No. A letter addressed to whom it may concern, with the clinician's details and registration on it, is accepted by most recipients and is the format that reuses cleanly. If a particular office insists on its own form or an addressed letter, ask the clinic for that in addition; the content is the same, only the framing changes.
You can ask why. Employers are generally entitled to enough information to understand the limitation and design an accommodation, and in most situations that does not require the diagnosis. If the employer has a specific reason, such as a safety-sensitive role, you can decide whether to share the full letter. Human rights commissions in each province publish guidance on what employers may ask for.
