Disclose before or after the offer: what the maths says

Section 60 of the Equality Act 2010 makes it illegal for a UK employer to ask about your disability before making a job offer. Most dyslexic applicants don't know this. So they spend the entire application phase agonising about whether to mention it on the form, and the employer has already been legally barred from using that information anyway.

In the US, ADA Section 12112(d) applies the same pre-offer prohibition. An employer cannot ask about disabilities, require medical examinations, or make inquiries likely to reveal a disability before extending an offer. This has been federal law since 1990, strengthened further by the ADA Amendments Act 2008.

Both laws create the same basic architecture: you hold the disclosure card until an offer lands. The question is what happens after that, and the UK and US answers diverge enough to matter.

The legal structure the employer cannot change

In the UK, Section 60 of the Equality Act 2010 carves out a narrow set of exceptions to the pre-offer ban. Employers can ask pre-offer if they're running positive action schemes, monitoring diversity, or assessing whether a specific physical requirement for the role can be met. For the vast majority of professional, office, and desk-based jobs, none of those exceptions apply.

What this means is that before any offer is made, the disclosure decision is entirely yours. The employer has no legal lever to pull it out of you. They cannot ask on an application form. They cannot ask in an interview. A diversity monitoring box is voluntary and its contents cannot legally be used in hiring decisions.

The same applies in the US. The EEOC is clear on this: pre-offer disability questions are prohibited regardless of how they're framed. "Do you have any conditions that affect your work?" is just as prohibited as "Do you have dyslexia?" The ban covers written questionnaires, verbal interview questions, and any pre-offer medical examination.

So far, the picture in both countries is the same: before an offer, you have no obligation and the employer has no right to ask. The shift happens the moment an offer is made.

Before an offer, the disclosure decision is entirely yours. After an offer, the legal landscape shifts and the timing of your disclosure starts to affect your practical position. Knowing this structure tells you how much power you hold in the early stages of any application.

What changes when the offer lands

In the UK, the duty to make reasonable adjustments under Equality Act 2010 sections 20 and 21 is triggered the moment your employer knows about your dyslexia. "Knows" means directly informed. It doesn't require a formal diagnosis certificate or any particular form of notification.

An email saying "I have dyslexia and would like to discuss what adjustments might be needed" is sufficient to start the clock. From that point, the employer must take reasonable steps to remove any substantial disadvantage your dyslexia creates compared to non-dyslexic colleagues. That duty covers onboarding materials, software access, performance criteria, written assessment timescales, and everything else from Day 1 of employment.

And they cannot legally withdraw a conditional offer solely because of the disclosure. If they try, that's a direct disability discrimination claim under the Act, with uncapped compensation in an employment tribunal.

In the US, the post-offer stage is where the employer's ability to ask medical questions opens up. Under ADA Section 12112(d)(3), after making a firm offer, an employer can ask disability-related questions and require medical examinations, as long as they apply the same process to all candidates offered that role. They can then assess whether the person can perform the core functions of the job.

But the key protection holds: they cannot withdraw the offer because of a disclosed disability unless they can demonstrate the person cannot perform the core functions of the role, with or without reasonable accommodation, or poses a significant risk to themselves or others. "We'd prefer someone without dyslexia" is a discrimination claim, not a legitimate business decision.

The EEOC is specific on this: once a post-offer disclosure is made and an accommodation is requested, the employer must engage in an "interactive process." A genuine back-and-forth about what adjustments would let you do the job. Refusing to engage in that process is itself an ADA violation.

Post-offer disclosure in both countries triggers legal protections that pre-offer disclosure does not guarantee. The employer cannot undo the offer because of the disclosure, and your duty-to-adjust clock starts immediately. Post-offer is the low-risk window for most dyslexic applicants who don't need interview adjustments.

If you need adjustments for the interview itself

Here is where timing gets genuinely complicated, and where a lot of standard advice falls short.

In both the UK and US, you're entitled to reasonable adjustments during the application and interview process, not just once you're in post. Extra time for written tests, a quiet room, questions in a different format, advance sight of interview topics: all of these are adjustable, and the employer must make the adjustment once they know you need it.

But they can only make the adjustment if you ask. And asking typically means naming a reason.

In the UK, you don't have to name dyslexia specifically. Saying "I have a learning disability and will need additional time for any written assessment" is enough to trigger the duty. The BDA confirms this: you can ask for interview adjustments without disclosing your full diagnostic picture. If the employer pushes for more detail, you can decide whether to share it.

The EEOC guidance for US applicants is consistent. You can request an accommodation during the application process without specifying the underlying condition. "I need extra time for written tests due to a learning disability" triggers the employer's obligation to engage. You're not handing them a diagnosis. You're requesting an adjustment.

In practice: if you're applying somewhere with written tests, psychometric assessments, or timed tasks as part of the interview process, request the adjustment when you're invited to interview. Don't wait until you arrive. Most employers need advance notice to arrange extra time or a different room.

If you don't need anything changed during the interview, you can hold disclosure until post-offer. If you do need something changed, request it at the interview invitation stage. You don't have to share a diagnosis at that point. "Learning disability" is enough in both jurisdictions.

The call: decision by situation

This is the part most disclosure guides skip. They list factors. They say "it depends." Here's what the evidence actually implies, by situation.

You've been invited to an interview and don't need any adjustments for the process itself. Wait. You have no obligation to disclose pre-offer. Let the interview happen. If you get an offer, disclose at that point. You'll have stronger legal protections and the employer has already decided they want you.

You've been invited to an interview and you'll need extra time or a different test format. Request the adjustment when you acknowledge the interview invitation. Say you have a learning disability and will need additional time or a format change for any written components. You don't need to say dyslexia at this stage unless you want to. Keep a written record of the request and their response.

You've received a conditional offer and haven't disclosed yet. Disclose now, in writing, before Day 1. An email is sufficient. State that you have dyslexia, briefly note what it affects at work (written communication, processing speed under time pressure, whatever's relevant), and flag that you'd like to discuss adjustments. This triggers the duty from your first day in the role and gives you the strongest footing before employment formally begins.

You've received a firm offer and you're about to sign. Disclose before you sign if you can. You want adjustments in place from Day 1, not worked out under pressure in month 3 when a performance concern has already been flagged. If you've already signed, disclose in your first week. The duty triggers on disclosure, not on signature date.

You've already started and haven't told them yet. Disclose now. Three months in is not too late. It means three months without adjustments you were entitled to, but disclosing now stops that clock. The disclosure decision guide covers in-employment disclosure specifically, including the scripts for approaching HR and line managers.

Your situation	When to disclose	What to say
Interview invite, no interview adjustments needed	After offer	Disclose in writing after conditional offer; request adjustments for Day 1
Interview invite, need extra time or format change	At interview invitation stage	"I have a learning disability and will need [specific adjustment] for written components"
Conditional offer received	Now, before Day 1	Email confirming dyslexia diagnosis, how it affects your work, request to discuss adjustments
Already in post, undisclosed	As soon as possible	Disclose in writing to HR; the duty to adjust triggers immediately on disclosure

One note on the "never" option. You're under no legal obligation to disclose at all, in either country, and there are circumstances where non-disclosure is a reasonable choice: short-term contracts, roles where dyslexia has minimal operational impact, workplaces with a documented poor track record on disability. The disclosure guide covers these scenarios in detail.

But if you need adjustments to do the job properly, and you're not disclosing because you're worried about the response: that calculation is usually wrong. Your employer's duty to make adjustments only exists once they know. And the law on what they can do with that information is more protective than most people realise.

For UK employees, the Access to Work calculator is worth running before your first adjustment conversation. Access to Work can fund a workplace needs assessment, text-to-speech software, specialist dyslexia coaching, and other adjustments specific to your role. Knowing what's available before you sit down with HR means you're not negotiating from scratch.

The math on disclosure timing points in one direction for most dyslexic job applicants: post-offer, pre-Day 1, in writing. Earlier than that only if you need interview adjustments. Later than that means you're working without protections you're already entitled to.

What the employer can and cannot do with the information

A common fear around disclosure is that the employer will use the information against you. That fear deserves a factual answer.

In the UK, Section 60 makes it unlawful to use pre-offer disability information in making a hiring decision. Any employer who rejects you at application stage after you've ticked a disability monitoring box would need to demonstrate that the decision had nothing to do with the disclosure. That's a difficult case to make at tribunal.

Post-offer, if they try to withdraw the offer on the basis of your dyslexia, that's direct disability discrimination. They'd need to show you cannot do the core duties of the role with or without reasonable adjustments. For most professional and desk-based jobs, that case doesn't hold. Dyslexia affects specific tasks; it doesn't prevent employment.

In the US, the ADA confidentiality provisions apply. Medical information you disclose during the hiring process must be kept in separate, confidential files. An employer cannot share your dyslexia disclosure with colleagues, clients, or other departments without your consent. The exceptions are narrow: supervisors can be told about necessary work restrictions; safety personnel can be told if your disability might require emergency treatment.

The Borg-Neal v Lloyds Banking Group case (UK Employment Tribunal, 2023, award of over £470,000 confirmed in 2024) is worth noting here. An employee was dismissed in a way that the tribunal found failed to account for how his dyslexia had affected his communication during a training session. The award included £23,000 for personal injury and £15,000 for injury to feelings. The size of the award reflected both the career impact and the employer's handling of the case throughout.

Tribunal awards in disability discrimination cases are uncapped in the UK. EEOC settlements for ADA violations carry compensatory and punitive damages capped by employer size ($50,000 to $300,000 depending on headcount), with uncapped back pay. The financial exposure for employers who mishandle post-disclosure situations is real and documented.

The information you disclose is legally protected in both jurisdictions. An employer who uses it to harm you has created a legal liability for themselves. Knowing this doesn't eliminate the risk of a bad employer response, but it reframes the decision: you're giving yourself legal standing, and they're the ones carrying the exposure.
