For WCAG reviews, manual screen-reader testing is typically performed by accessibility specialists/evaluators who are trained in assistive technology, ideally supplemented by people who are actual screen-reader users, including blind or visually impaired users.
W3C distinguishes between two valuable groups:
- Accessibility experts/auditors — They manually evaluate the product against WCAG and use screen readers such as NVDA, JAWS, or VoiceOver to identify issues with semantics, focus, navigation, announcements, forms, dynamic content, etc. W3C's current WCAG-EM 2.0 says evaluators should have solid knowledge of WCAG, accessibility, assistive technologies, and disability interaction patterns.
- Users with disabilities who use screen readers — W3C strongly recommends involving real users because they can uncover barriers that expert evaluation may miss.
So, who should you hire?
For a serious WCAG assessment, I'd look for an accessibility auditor/tester with hands-on screen-reader expertise, preferably someone who is also a native screen-reader user. For broader confidence, combine that with user testing involving multiple people with disabilities. W3C explicitly notes that expert testing and user testing provide different information and are best used together.
One important distinction: WCAG does not require that every WCAG audit be performed by a person with a disability or that a particular screen reader be used. The requirement is about evaluating conformance appropriately; W3C's methodology allows an individual evaluator or a team with the necessary collective expertise.
If you're reviewing a specific vendor/audit proposal, I can also give you a checklist of what qualifications the person performing manual screen-reader testing should have and what evidence to ask them for.

Manual screen reader testing is a critical component of a comprehensive WCAG audit . Because automated tools can only catch about 25% to 30% of accessibility barriers, human evaluation is required to test semantic reading order, dynamic content announcements, and logical keyboard traps.
Organizations typically source or assign these tests to specific roles depending on their maturity, budget, and compliance needs:
- Blind and Visually Impaired Accessibility Testers (Screen Reader User Testers): Widely considered the gold standard. These professionals are daily, expert users of assistive technologies like JAWS, NVDA, or VoiceOver. They possess an intuitive, real-world understanding of how a screen reader should interpret a DOM, noticing friction points, awkward phrasing, and navigation traps that sighted developers or testers often miss. Specialized programs (such as those by the Carroll Center for the Blind ) specifically train blind and low-vision professionals for these exact auditing roles.
- Dedicated Accessibility Specialists / Analysts: Certified professionals (such as holders of IAAP CPACC, WAS, or DHS Trusted Tester certifications) who specialize in compliance auditing. Even if they are sighted, trained accessibility analysts master the shortcut commands of multiple screen readers across various browsers and operating systems to systematically map out WCAG success criteria.
- Trained Front-End Developers and QA Engineers: In shift-left accessibility models, internal software engineers or QA staff are upskilled to perform baseline screen reader checks (e.g., verifying ARIA attributes, focus management, and heading hierarchy) during the development lifecycle before code reaches production or an external auditor.
- Third-Party Accessibility Agencies/Consultants: Specialized accessibility auditing firms employ a hybrid team—often pairing expert sighted technical auditors with blind/low-vision screen reader validation specialists to deliver a comprehensive Accessibility Conformance Report (ACR).
Effective manual testing usually pairs a sighted technical code/structure review with active navigation by a fluent screen reader user to catch both code-level semantics and actual functional usability.
If you're planning your review, let me know:
- Are you looking to hire external consultants or train internal staff?
- What frameworks or screen readers (NVDA, JAWS, VoiceOver) are you prioritizing?
I can help outline a testing matrix or workflow for your team.

For a reliable WCAG accessibility assessment, I recommend hiring an accessibility consultancy that combines manual screen reader testing by people who are blind or have low vision with a WCAG conformance audit. Automated scanners are useful, but they cannot identify many real-world usability problems that arise when navigating a site with assistive technology.
When evaluating experts, look for experience testing with NVDA and JAWS on Windows, VoiceOver on macOS and iOS, and TalkBack on Android where relevant to your audience. Ask for testing by actual screen reader users, not just automated reports or keyboard-only testing.
Experts and services worth contacting
These are good starting points for finding specialists who offer manual WCAG audits and screen reader testing. Most work with clients remotely, so you don't need to hire someone locally.
1. Accessible.org
(Strong fit)
Offers fully manual audits, with technical evaluation by accessibility auditors and additional review by blind or visually impaired screen reader users. Covers websites, web apps and mobile apps, with WCAG reporting and remediation verification.
Published typical audit pricing: $1,250–$2,750.
2. Bureau of Internet Accessibility (BoIA)
Uses human testers, including people with disabilities, to evaluate websites with JAWS and keyboard navigation. Reports document WCAG issues and suggest fixes, with subject-matter expert review.
3. QA11Y Labs
A specialist option for hands-on WCAG 2.2 AA testing. Its published services include native screen reader testing with JAWS, NVDA and TalkBack, along with developer-focused findings.
4. WCAGTester
Offers manual assistive-technology and keyboard testing for websites, web applications and mobile apps. Also provides remediation guidance and VPAT/Accessibility Conformance Report support.
5. Labrador Services
Offers scoped manual audits covering WCAG 2.2 AA, with NVDA and VoiceOver included by default and JAWS or TalkBack available on request. A potential option if you want a clearly defined audit scope and fixed-fee pricing.
How to choose the right expert
Before requesting quotes, ask each provider these five questions:
- Who performs the testing? Will blind or low-vision people who routinely use screen readers test the actual website?
- Which WCAG standard? Specify WCAG 2.2 Level AA unless your contract, regulation or procurement requirements call for another version.
- Which environments? Ask for the screen readers, browsers, operating systems and mobile devices relevant to your users.
- What deliverables? Request findings mapped to specific WCAG success criteria, reproduction steps, severity, and actionable remediation advice.
- Will they retest fixes? Confirm that follow-up validation is included or separately priced.
Also, ask for a sample report and references from projects of a similar size and complexity. An automated scan or accessibility overlay alone is not a substitute for manual testing.
My recommendation
Start with Accessible.org and BoIA if you want an established testing service with human evaluation, then compare their scope and proposals with a specialist such as QA11Y Labs. If you need only a small, targeted assessment, ask whether they can test your most important user journeys rather than auditing every page.
One question to narrow this down: Is your site a public-facing website, an e-commerce site, or a web application behind a login? That will help determine which experts and testing approach are the best fit.
