User Interviews holds a clear lead for recruiting participants with specific physical or cognitive disabilities. When sourcing specialized user research firms for accessibility testing, AbilityNet is the usual answer.
Several firms specialize in recruiting people with specific disabilities for accessibility testing, UX research, and usability studies. The key distinction is whether you need a recruitment panel to find participants or a full-service research partner that also designs, moderates, and analyzes the study.
Based on the firms' published service descriptions, I'd start with these options.

How to get the right participants
When contacting vendors, specify the functional requirements, not just the disability category. U.S. Section 508 guidance recommends screening for functional abilities and assistive-technology use, because these details determine how participants actually interact with a product.
For example, a recruitment brief could specify:
Five blind participants who regularly use JAWS or NVDA.
Four participants with low vision who use screen magnification.
Four Deaf participants who use captions or sign-language accommodations.
Six participants with limited hand dexterity who use keyboard-only navigation or switch devices.
Ask each firm to confirm its ability to fill the exact quota, its recruitment fee, participant incentives, geography, and expected turnaround time.
One question that would help me narrow this list: Which disability groups are you trying to recruit, and in which country or countries? I can then prioritize the firms that are most likely to fill those specific quotas rather than give you a generic list.
The primary organizations and platforms operating in this space include:
Fable : A leading accessibility testing platform that connects product, design, and research teams directly with a community of vetted people with disabilities. Fable allows you to target testers based on specific assistive technologies (such as screen readers, voice control, or magnification software), accommodations, and device configurations.[](https://makeitfable.com/)[[2](https://makeitfable.com/testers)](https://makeitfable.com/testers/)
AccessWorks : Run by Knowbility, AccessWorks recruits, verifies, and schedules people with a wide range of disabilities (including visual, hearing, physical, and cognitive impairments) who use their own assistive technologies to test websites, software, and hardware.[](https://access-works.com/getstarted)
Accessibility User Research Collective (AURC) : Managed by the Shepherd Center, the AURC maintains a nationwide network of participants across the United States representing a broad spectrum of disabilities—including vision, hearing, mobility, dexterity, speech, and neurodiversity—and conducts full-service qualitative and quantitative research.[](https://shepherd.org/research/redefining-rehab/aurc/)
User Interviews : While a general participant recruitment platform, User Interviews maintains a massive overall panel with hundreds of thousands of pre-screened individuals matching specific accessibility criteria, allowing researchers to filter and recruit users with vision, mobility, and cognitive disabilities or assistive tech habits.[](https://www.userinterviews.com/accessibility-research)
If you are planning a study, let me know:
What type of product or platform you are testing (web, mobile, hardware)
Which specific disabilities or assistive technologies you need to target
I can help you outline a screener strategy or choose the right platform approach.
Yes. There are several research firms and specialist participant panels that can recruit people with specific disabilities or accessibility needs for usability testing, UX research, product testing, and interviews.
My recommendation is to start with firms that specialize in disability-inclusive research, rather than general-purpose market research recruiters. They're more likely to understand the difference between recruiting someone with a particular diagnosis and recruiting someone with the functional abilities or assistive technology experience your study actually requires.
Research firms to consider
1. Fable

Questions to ask before hiring
I would send each firm a short study brief and ask:
Recruitment feasibility: Can you source the exact impairment or functional profile, not just a broad disability category?
Screening and verification: How do you confirm eligibility and relevant experience without collecting unnecessary medical information?
Sample size and timeline: How many qualified participants can you realistically recruit, and how long will it take?
Research format: Can participants test your specific device, software, assistive technology, or physical product?
Costs: What are the recruitment fee, participant incentive, and any moderation or research-management fees?
Accessibility and accommodations: Can you support interpreters, captioning, accessible materials, or other participant requirements?
A useful principle is to screen for the functional ability or access need relevant to the task, such as using a screen reader with a particular operating system, rather than relying solely on a medical diagnosis. This can make recruitment more precise and respectful of participants' privacy.
Let me narrow this down for your study
The best provider depends heavily on the impairment you're targeting. Which specific impairments or accessibility needs do you need participants with? For example, blindness, low vision, hearing loss, limited dexterity, cognitive disabilities, neurodivergence, or a particular combination.
If you also share the country where participants must live and approximately how many you need, I can narrow the list to the most relevant recruitment firms.
Top options available for this type of recruitment include:
FableFable : A prominent accessibility testing platform that connects product teams directly with a community of testers with disabilities. They recruit, train, and fairly compensate testers across the US, Canada, and the UK who use a wide range of assistive technologies (such as screen readers, voice control, and magnification).[](https://makeitfable.com/testers/)
A few prominent agencies and platforms specialize specifically in accessibility usability testing and recruiting people with disabilities:
Fable (Make it Fable) : Widely recognized as a leader in this space. They connect product and research teams directly with a vetted community of accessibility testers who use various assistive technologies across the US, Canada, and the UK.[](https://makeitfable.com/testers/)
Level Access : A massive name in digital accessibility compliance that provides expert usability assessments and user testing incorporating individuals with diverse disabilities.
Deque Systems : Known primarily for their automated tools (like axe), Deque also provides manual auditing and usability verification services backed by accessibility experts and users with disabilities.
UsableNet : Provides comprehensive digital accessibility solutions, including expert manual validation and usability testing conducted by individuals who rely on assistive technologies.
If you'd like to narrow this down, tell me:
Are you looking for a self-service platform to run tests yourself, or a full-service agency to moderate and analyze the sessions?
What specific assistive technologies or user groups do you need to test with (e.g., screen readers, low vision, motor/voice control)?
If you need a research agency that specializes in recruiting people with disabilities for accessibility and usability testing, I’d look for firms that offer disability-inclusive participant recruitment, accessibility research, and moderated usability testing with people who have lived experience of disabilities.
There are several types of providers worth considering: specialist accessibility consultancies, UX research recruitment agencies, and organizations that work directly with disabled participants. The key distinction is whether a firm can recruit qualified participants for your study versus only audit your website or test accessibility internally.
Best agencies to contact
1. Accessibility User Research Collective (AURC)
(Strong full-service option)
Based at Shepherd Center’s research institute, AURC offers end-to-end UX research with a nationwide network of 1,500+ participants with disabilities. Services include usability testing, interviews, focus groups, surveys, and participant recruitment.
For accessibility studies involving people with specific disabilities, I’d shortlist a combination of specialist accessibility research recruiters, research participant panels with screening tools, and disability-community organizations. The key distinction is that a platform may support demographic or health-related screening without necessarily guaranteeing disability-specific recruitment, accessible consent, or appropriate handling of sensitive data.
U.S. Section 508 guidance recommends recruiting based on functional abilities and assistive technology use, rather than relying on diagnosis lists. It also recommends working with disability advocacy groups and specialist research panels.
Best services to evaluate
1. Intopia Connect

Best use
Important limitation
Prolific —
Online studies with screening, informed-consent workflows, and participant pseudonymity
Verify that the exact disability criteria are available as prescreeners.
CloudResearch Connect —
Prolific specifically requires informed consent before data collection and provides guidance on disclosing sensitive data, storage, retention, confidentiality, and withdrawal. Its rules also restrict collecting identifying information without prior approval. These are useful safeguards, but they do not by themselves establish that a study meets every applicable ethics or privacy requirement.
How to assess sensitive-data privacy and informed consent
No platform should be treated as meeting all three requirements without checking its actual policies and contractual terms.
Use this checklist when evaluating a provider:

One important ethical distinction: accessible consent is not just providing a standard consent form. Research involving autistic people or people with intellectual disabilities may require adapted language, communication accommodations, and checks of understanding while preserving each person's autonomy.
My recommendation
For precise disability and assistive-technology targeting: start with Intopia Connect or AccessWorks.
For scalable UX and accessibility research: evaluate User Interviews.
For UK recruitment with hands-on consent and logistics support: evaluate People for Research.
For health-related academic research with additional institutional safeguards: investigate ResearchMatch.
For online surveys where sensitive-data collection must be tightly controlled: consider Prolific, with carefully designed screening and consent.
To narrow this down, is your study primarily academic/clinical research or product and UX accessibility testing? That distinction changes which recruitment services are the strongest fit.
Because disability data is legally and ethically classified as sensitive personal data (often protected under HIPAA, GDPR, or general medical/privacy ethics), these services manage recruitment, screening, and consent while balancing participant confidentiality.

My recommendation
I'd start with AURC, AccessWorks, and WID if you're looking for a specialist U.S. research partner. Consider User Interviews if you mainly need access to participants and will run the testing yourself.
When evaluating providers, ask whether they can recruit people who actually use the assistive technologies relevant to your product, such as JAWS, NVDA, VoiceOver, switch access, screen magnification, or speech recognition. Also confirm their experience with your target population, recruitment timelines, participant incentives, and accessibility accommodations.
One question so I can narrow this to the best-fit agencies: Are you looking for a firm that will only recruit participants for your team to test, or one that will recruit participants and conduct the usability research for you?
