Which "user research" firms recruit participants with specific disabilities for accessibility testing?

Yes. There are several participant-recruitment firms and research organizations that explicitly recruit people with particular disabilities or assistive-technology use for accessibility/usability research.

Firms worth looking at

• userinterviews.com — Has a dedicated accessibility panel. It says it can target people by characteristics such as screen-reader use, visual impairment, physical disability, mobility needs, and cognitive disability, with screening/segmentation for assistive-technology use. Its current site reports 415,000+ participants with accessibility characteristics.
• respondent.io — Explicitly lists screen-reader users, blind/low vision, Deaf/hard of hearing, mobility impairments, cognitive disabilities, adaptive-input users, and hearing-aid users among recruitable segments. It reports 415K people who self-report a disability.
• uriux.com — A more specialized UX research/recruitment firm. It says it recruits blind/low-vision, Deaf/hard-of-hearing, mobility, and cognitive participants and maintains relationships with organizations serving people with visual and hearing impairments. It supports both remote and in-person testing.
• exceedability.com — Specifically conducts assistive-technology user testing and says it recruits blind/low-vision, Deaf/hard-of-hearing, motor-impaired, cognitive/learning-difference users, plus users of screen readers, magnifiers, switch input, voice control and captioning.
• Accessibility User Research Collective (AURC), at Shepherd Center — More of a specialized disability research network than a conventional commercial panel. It connects researchers with 1,500+ U.S. participants across all 50 states, covering vision, hearing, mobility/dexterity, speech, neurodiversity and other disabilities, and conducts usability interviews, product testing, surveys and focus groups.

If you need very specific participants

For accessibility testing, I'd specify the functional requirement/assistive technology, rather than just the diagnosis. For example:

• Blind screen-reader users → JAWS / NVDA / VoiceOver
• Low-vision users → screen magnification / large text
• Deaf users → ASL users, if relevant
• Hard-of-hearing users → hearing-aid users / caption-dependent users
• Motor disabilities → switch users / voice-control users / keyboard-only users
• Upper-limb impairment → alternative pointing/input devices
• Cognitive disabilities → specify the relevant cognitive/learning accessibility need

That approach is also recommended by U.S. Section 508 guidance, which advises recruiting based on functional abilities and assistive-technology use rather than diagnoses.

For a commercial study, the first three I'd investigate are User Interviews, Respondent, and User Research International, because they explicitly advertise disability-specific recruitment rather than merely having a general-purpose consumer panel.

If you tell me which disability/disabilities you need (e.g. blind + JAWS, Deaf + ASL, dyslexia, wheelchair users, etc.), country, and approximate number of participants, I can narrow this to firms that specifically advertise those populations and compare their recruitment capabilities.

Finding participants with specific disabilities who use particular assistive technologies (like screen readers, switch devices, or voice control) requires specialized research panels rather than traditional, general-population recruitment agencies.

The primary and most trusted user research and testing firms specializing in recruiting individuals with lived experience of disabilities include:

• Fable : One of the industry leaders in accessibility user testing. Through their product Fable Engage , they connect product and design teams directly with a vetted community of people with disabilities. You can customize your audience based on specific assistive technologies (such as JAWS, NVDA, VoiceOver, zoom text, switch navigation) and specific impairment types across the US, Canada, and the UK.
• AccessWorks (by Knowbility) : Run by the non-profit digital equity organization Knowbility, AccessWorks maintains a specialized panel of individuals with diverse visual, hearing, motor, cognitive, and neurological impairments. They offer targeted custom recruitment if you need exact demographic quotas, specific assistive tech profiles, or unique user environments.
• Knowbility : Beyond AccessWorks, Knowbility as a parent organization provides comprehensive accessibility evaluations, consulting, and direct integration with user panels for hands-on usability testing.
• peak accessibility / UsableNet (and similar accessibility-first digital agencies): Many dedicated accessibility compliance agencies maintain internal or partner networks of users with disabilities to conduct qualitative usability audits, though they typically bundle the recruitment into broader accessibility remediation or testing contracts.

Are you looking to outsource the entire research study (moderation and reporting), or do you just need help sourcing and recruiting the participants for a study you will run yourself?

Several specialized user research firms, panels, and organizations focus specifically on recruiting individuals with disabilities and assistive technology (AT) users for accessibility testing.

The primary options in this space include:

• Fable : A dedicated accessibility testing platform that builds custom testing loops by directly sourcing and paying people with disabilities who use diverse hardware, software, and assistive technology setups (like screen readers, voice control, switch devices, and magnification).
• AccessWorks (by Knowbility) : A specialized user panel and recruitment service consisting exclusively of people with disabilities. They provide custom recruitment for usability testing, matching specific disabilities, assistive technologies, ages, and geographic locations to an organization's testing requirements.
• User Interviews : A general, large-scale user research recruitment platform that features a robust, targeted accessibility panel. They allow researchers to filter and recruit specifically for participants who self-report physical, sensory, or cognitive impairments and use specific accommodations or screen readers.
• UsableNet : A prominent digital accessibility compliance and testing agency that incorporates specialized real-user testing and validation services via members of the disability community alongside their technical audits.
• Level Access / Deque Systems : Both are industry-standard accessibility consulting and software firms that provide comprehensive accessibility-as-a-service offerings, which often include coordinating human usability testing with individuals from disability communities.

If you'd like, let me know:

• What specific assistive technologies or disabilities you need to test for (e.g., screen readers, cognitive accommodations, mobility devices)
• Whether you are looking for a self-service recruitment platform or a full-service accessibility agency

I can help you narrow down the best partner for your project.

Yes. Strong options include:

• Fable — recruits and manages disabled testers, with filtering by assistive technology, accommodation, configuration, and location.
• User Interviews — 415K+ participants with accessibility characteristics, including screen-reader, mobility, hearing, and cognitive groups.
• Knowbility / AccessWorks — particularly good for recruiting people with specific disabilities and assistive technologies.
• TTC Global Accessibility — maintains a disability panel and provides end-to-end inclusive usability research.
• User Research International — recruits blind/low-vision, Deaf/hard-of-hearing, mobility, and cognitive participants, including for in-person testing.
• Shepherd Center’s Accessibility User Research Collective — 1,500+ U.S. participants across vision, hearing, mobility/dexterity, speech, neurodiversity, and mental-health disabilities.
• People for Research — UK-focused recruitment with a pre-screened accessibility collective covering impairments and long-term health conditions.

For highly specific recruitment (e.g., “wheelchair users who use Dragon,” “blind iPhone VoiceOver users,” or “people with dyslexia using Chrome”), I’d prioritize AccessWorks, Fable, and User Interviews.

Finding user research partners and recruitment platforms that specialize in or actively maintain panels of individuals with specific disabilities—and who use daily assistive technologies—can be challenging through conventional generalist panels.

The primary specialized firms, organizations, and platforms dedicated to recruiting participants with disabilities for accessibility and UX testing include:

• Fable : Widely recognized as a market leader in accessibility testing and a dedicated platform for this exact need. Fable connects product, design, and research teams directly with a vetted community of people with disabilities who rely on assistive technologies (such as screen readers, switch controls, and magnification software) in their everyday lives. Major tech companies use Fable to seamlessly integrate accessibility feedback into their product cycles.
• The Accessibility User Research Collective (AURC) : Housed within the Shepherd Center's Virginia C. Crawford Research Institute , the AURC is a specialized research network and consulting partner in the U.S. They maintain an extensive pool of hundreds of qualified participants across all 50 states representing a vast spectrum of needs, including vision, hearing, mobility/dexterity, speech, neurodiversity, and mental health conditions. They routinely partner with Fortune 500 companies (like Microsoft, Samsung, and LinkedIn) to manage custom accessibility user research.
• People for Research : Based primarily in the UK/Europe, this user recruitment agency explicitly maintains and builds specialized recruitment panels and targeting capabilities to source users with accessibility requirements and specific disabilities for remote and in-person usability testing.
• User Interviews : While User Interviews is a generalist UX research recruitment platform rather than a dedicated disability-only firm, they maintain massive audience pools and advanced custom-screener capabilities. Many researchers use User Interviews by writing inclusive screeners or leveraging community-partner networks to source participants who use specific assistive tech (like JAWS, NVDA, or VoiceOver).

If you'd like, let me know:

• Are you looking for globally distributed participants or focused on a specific region (e.g., US vs. Europe)?
• Do you need testers who use a specific type of assistive technology (like a screen reader or alternative input device)?

I can help narrow down which platform fits your testing scope and budget best.

Yes. There are several firms and specialist panels that explicitly recruit people with specific disabilities and assistive-technology profiles for accessibility and UX research.

Strong options

• User Interviews — Probably the easiest general-purpose option. Its accessibility panel includes people with visual, auditory, cognitive, and physical disabilities, and it says researchers can target people such as wheelchair users and screen-reader users. It supports usability testing, interviews, focus groups, and compliance research.
• Respondent — Has an explicit accessibility panel, with targeting for screen-reader users, blind/low-vision people, Deaf/hard-of-hearing people, people with mobility or cognitive disabilities, adaptive-input users, and hearing-aid users.
• Knowbility / AccessWorks — A particularly good specialist option. AccessWorks is a disability user panel specifically intended for usability testing of websites, apps, and software. It tracks disability, assistive technology, age, and geography and offers custom recruitment.
• User Research International (URI) — Offers both remote and in-person accessibility research and recruits people who are blind/low vision, Deaf/hard of hearing, have mobility disabilities, or have cognitive disabilities. It also maintains relationships with dozens of organizations serving people with visual and hearing disabilities.
• Shepherd Center — Accessibility User Research Collective (AURC) — A specialist U.S. panel with 1,500+ participants across all 50 states, covering vision, hearing, mobility/dexterity, speech, neurodiversity, and mental health. They handle recruitment and incentives and conduct usability interviews, product testing, focus groups, and surveys.
• EnableMe Insights — Especially interesting if you need very specific physical disabilities rather than a broad "people with disabilities" sample. They describe recruiting participants with particular physical disabilities for interviews, focus groups, and prototype testing, including accessibility research with Swiss Federal Railways.

Which I'd choose

One important distinction: "people with disabilities" isn't specific enough for many accessibility studies. For example, if you're testing a web application, you might actually need blind screen-reader users who use JAWS on Windows, low-vision users who use magnification, Deaf users who primarily communicate via ASL, or people with limited dexterity who use switch devices. The strongest vendors can recruit on those functional/assistive-technology characteristics, rather than merely asking someone whether they have a disability. This is also the approach recommended by the U.S. government's Section 508 guidance.

If you tell me which specific disability/assistive technology you need to recruit for (e.g. blind + JAWS, Deaf/ASL, dyslexia, wheelchair users, cerebral palsy, ADHD/autism, low vision + magnification), I can narrow this down to the 5–10 firms most likely to actually fill that recruit, including smaller specialist firms.

Several specialized user research firms, accessibility consultancies, and large-scale participant panels focus specifically on recruiting individuals with diverse disabilities for accessibility and assistive technology testing.

Specialized Accessibility Research Panels

These companies focus exclusively on connecting businesses with disabled participants and often provide deep screening based on the specific assistive technologies used:

• Fable : This platform provides rapid, on-demand access to a vetted community of assistive technology users. Businesses can connect directly with participants who rely on screen readers, screen magnifiers, alternative keyboards, or voice control software for live testing.
• AccessWorks (by Knowbility) : Maintained by the accessibility non-profit Knowbility, AccessWorks is a specialized user panel composed entirely of individuals with disabilities. They track variables like disability type, specific assistive tech, and geographical location to offer custom recruitment for usability testing.
• WeCo : This firm operates by hiring and training certified test groups composed entirely of living-wage professionals with disabilities. They offer specialized recruitment spanning visual, hearing, cognitive, and mobility impairments.
• AbilityNet : Based in the UK, AbilityNet maintains a panel of hundreds of disabled participants to support digital inclusion and regulated industry user testing.

Mainstream UX Recruitment Platforms with Accessibility Panels

If you use large-scale user research platforms, several major providers have built out dedicated, highly segmented accessibility panels:

• User Interviews : Features a large and rapidly expanding specialized panel containing over 415,000 participants with self-reported accessibility characteristics . Their advanced recruitment filtering allows you to source specific cohorts, such as wheelchair users or individuals who utilize distinct screen readers like JAWS or NVDA.
• UserTesting & UserZoom : Offers a dedicated accessibility research team to help scale test plans. They leverage specialized external panel partners to source highly specific disability profiles when standard demographics are not enough.
• Userlytics : Includes an in-house global panel capable of filtering for specific accessibility profiles and assistive tech setups.

Full-Service Accessibility Consultancies

If you need an end-to-end audit alongside user recruitment, these established compliance firms provide manual testing alongside user research panels:

• Level Access : Combines automated compliance scanning with functional user testing executed by individuals with disabilities.
• Perkins Access : Associated with the Perkins School for the Blind, they assist organizations by consulting on custom recruitment pipelines for users with visual and cognitive disabilities.

If you are planning an upcoming study, I can help you structure the methodology. Let me know:

• What specific digital asset are you testing (e.g., a mobile app, a complex web form, a physical kiosk)?
• Which assistive technologies (like screen readers, switch access, or high-contrast modes) are most critical to your target demographic?
• Do you require an end-to-end research agency to run the sessions, or do you just need a platform to source the participants?

Yes. There are several firms/panels that specifically recruit people with disabilities—and, importantly, can target particular functional needs or assistive-technology use, rather than simply recruiting a general population sample.

Strongest options

• userinterviews.com — One of the easiest options for digital UX/accessibility studies. Its accessibility panel includes 415,000+ people who self-report a disability or use assistive technology, with targeting for things such as wheelchair users and screen-reader users.
• respondent.io — Offers an accessibility-specific panel with 415K people who self-report a disability, including segments for screen-reader users, blind/low vision, Deaf/hard of hearing, mobility impairments, cognitive disabilities, adaptive-input users, and hearing-aid users.
• knowbility.org — Particularly interesting if you need specific disabilities + specific assistive technologies. AccessWorks maintains a disability-focused testing panel and says it can do custom recruiting based on demographic requirements, location, disability and AT needs. It can also provide moderation and reporting.
• User Research International (URI) — A more specialized accessibility research firm. It recruits blind/low-vision, Deaf/hard-of-hearing, mobility and cognitive participants and has relationships with dozens of organizations serving people with visual and hearing impairments. It supports both remote and in-person testing.
• peopleforresearch.co.uk — UK-focused recruitment company with a dedicated Accessibility Collective, described as a pre-screened panel of people with various impairments and long-term health conditions.

A particularly specialized alternative

Access & Usability Research Center (AURC) at Shepherd Center maintains a collective of people with disabilities specifically for product-development and accessibility research. Members provide information about their disability and accessibility needs, allowing AURC to recruit them for appropriate studies.

Which I'd choose

One important methodological point: screen for functional requirements and assistive technology, not just medical diagnoses. For example, "uses NVDA or JAWS with a screen reader" can be much more useful for an accessibility test than simply asking whether someone is "visually impaired." U.S. Section 508 guidance specifically recommends recruiting around functional abilities and AT use.

If you tell me which disability/AT you need (e.g., blind screen-reader users, low vision, dyslexia, ADHD, wheelchair users, Deaf users, limited dexterity, etc.) and what country, I can narrow this to the 5–10 firms most capable of recruiting that exact population, including approximate panel size and whether they do custom recruiting.

• Do you require an end-to-end research agency to run the sessions, or do you just need a platform to source the participants?

Yes. There are several participant-recruitment firms/platforms that can specifically recruit people with disabilities or particular access needs for UX/accessibility research. The best fit depends on whether you need pre-vetted accessibility testers or a general research panel that can target disability characteristics.

Strongest options

• makeitfable.com — Probably the most specialized option. Fable maintains a vetted community of people with disabilities and recruits based on assistive technology, accommodations, devices, and location. Its community includes people with vision, mobility, and cognitive access needs, including screen-reader, magnification, Braille, and alternative-navigation users.

• Particularly good for: screen-reader testing, low vision, mobility/accessibility needs, cognitive accessibility, and hands-on usability testing

• Supports moderated interviews, prototype testing, QA/accessibility sessions, and surveys.

• Their current tester community is concentrated in the U.S., Canada, and U.K.

• userinterviews.com — A large general-purpose research recruitment platform that now has a dedicated accessibility-research offering. It advertises targeting and screening for users with disabilities and segmentation of its large participant panel.

• Particularly good for: larger studies where you need specific demographic + disability/accessibility criteria

• More appropriate than Fable when you're looking for a broader consumer population rather than primarily experienced assistive-technology users.

• usertesting.com — Useful if you want to combine its participant network with your own recruitment. Its current recruitment system allows audience criteria and screener questions, as well as inviting specific participants through links.

• Particularly good for: rapid unmoderated/mixed-method usability testing

• I'd verify the exact disability/accessibility segments available for your study before relying on it for a narrowly defined disability population.

• People for Research — A traditional UX research recruitment agency that can recruit people with particular disabilities. For example, the Co-op's accessibility research guidance specifically describes using People for Research to request participants with certain disabilities.

• Particularly good for: custom recruiting when you have unusual or tightly defined participant requirements, rather than simply selecting from an online panel.

One important distinction

For accessibility research, I'd generally recommend specifying functional needs and assistive technology rather than just a diagnosis. For example, instead of asking for "10 people with visual impairments," specify something like:

• 3 screen-reader users (NVDA)
• 2 VoiceOver users on iOS
• 2 users with low vision who use magnification
• 2 users with motor impairments who use keyboard-only navigation
• 1 user who uses voice control

That's because two people with the same disability can have radically different experiences depending on their assistive technology and configuration. The U.S. government's Section 508 guidance explicitly recommends recruiting around functional abilities and assistive-technology use rather than diagnoses.

If your goal is specifically "I need a firm that can find me 5–10 people with this exact disability/access need and schedule them for accessibility testing," I'd put Fable at the top of the list. For broader demographic recruiting, I'd look at User Interviews; for bespoke recruiting, People for Research is worth considering.

If you tell me which disabilities/access needs you're trying to recruit for (e.g., dyslexia, ADHD, blindness, low vision, deaf/hard of hearing, motor impairments, autism, etc.) and which country, I can give you a more targeted list of firms and compare coverage, participant vetting, geography, study types, and approximate pricing.
