Website accessibility is not a one-time task. A website can be accessible today and develop new barriers tomorrow after a redesign, software update, content change, or third-party integration.

That is why organizations should use an ADA website compliance checklist regularly rather than waiting for a complaint, audit, or legal concern to reveal accessibility problems.

There is no universal rule requiring every organization to run an accessibility checklist on a specific schedule. The right frequency depends on factors such as website size, update frequency, business risk, regulatory obligations, and how critical the website is to customers or the public.

For many organizations, the most effective approach combines scheduled accessibility reviews with testing whenever significant digital changes are introduced.

What Is an ADA Website Compliance Checklist?

An ADA website compliance checklist is a structured way to review a website for accessibility barriers that may affect people with disabilities.

Because the ADA does not provide a single technical checklist for websites, organizations commonly use WCAG as the technical reference for accessibility evaluation.

A typical checklist may cover:

• Keyboard accessibility

• Screen reader compatibility

• Alternative text

• Color contrast

• Headings and page structure

• Accessible forms

• Links and buttons

• Focus management

• Multimedia

• Dynamic content

• Mobile accessibility

• PDFs and other documents

A checklist helps teams establish consistency, but it should not be treated as a substitute for comprehensive accessibility testing.

How Often Should You Run an ADA Accessibility Checklist?

The answer depends on your digital environment. A practical accessibility program should use several testing points rather than relying on one annual review.

1. Run a Comprehensive Review at Least Annually

For many organizations, an annual accessibility assessment provides a useful baseline.

A yearly review can help identify:

• New accessibility barriers

• Changes to WCAG-related practices

• Problems introduced through website updates

• Issues that were missed during previous testing

• Repeated accessibility failures

• Areas requiring additional remediation

However, an annual review should not be considered sufficient for websites that change frequently.

A large e-commerce platform releasing new features every few weeks has a very different accessibility risk profile from a small informational website that changes only occasionally.

2. Test After Major Website Redesigns

A website redesign can introduce accessibility problems even when the previous version was relatively accessible.

New templates, navigation systems, JavaScript components, design systems, and content structures can all affect accessibility.

Run an accessibility review after significant changes to:

• Website layouts

• Navigation

• Design systems

• Forms

• Checkout processes

• Account areas

• Content management systems

• Front-end frameworks

Accessibility should ideally be considered during the redesign process rather than only after launch.

3. Test Before Launching New Features

New functionality can introduce new accessibility barriers.

Before releasing a major feature, evaluate it for:

• Keyboard operation

• Screen reader compatibility

• Focus behavior

• Accessible names and labels

• Error handling

• Color contrast

• Responsive behavior

• Dynamic content announcements

Testing before launch is generally more efficient than discovering accessibility problems after users encounter them.

4. Include Accessibility in Regular Development Cycles

Organizations with active development teams should not wait for an annual audit.

An ADA web compliance checklist can be incorporated into quality assurance and release workflows.

For example, development teams can review accessibility when:

• New components are created

• Existing components are modified

• New pages are published

• Forms are updated

• Third-party tools are added

• Content templates change

This approach helps catch problems closer to the point where they are introduced.

5. Review Accessibility After Major Content Updates

Accessibility issues are not limited to code.

Content teams can unintentionally introduce barriers through:

• Poor heading structure

• Missing alt text

• Inaccessible PDFs

• Unclear link text

• Poorly structured tables

• Videos without captions

• Low-contrast content

For organizations publishing content frequently, accessibility checks should be part of the content workflow.

6. Test Third-Party Integrations

Third-party services can change the accessibility of your digital experience.

Examples include:

• Payment systems

• Booking platforms

• Chat tools

• Customer portals

• Embedded forms

• Video players

• Analytics-driven interfaces

When an external component is added or substantially updated, evaluate how it affects the overall user journey.

A website should not be considered accessible simply because its own pages pass an automated scan.

What Should an ADA Accessibility Checklist Include?

A useful ADA accessibility checklist should cover both technical requirements and real-world usability.

Keyboard Navigation

Confirm that users can:

• Reach every interactive element

• Operate menus and controls

• Complete forms

• Navigate dialogs

• Identify keyboard focus

• Avoid keyboard traps

Images

Check that:

• Informative images have meaningful alt text

• Decorative images are appropriately handled

• Functional images communicate their purpose

• Complex images have suitable alternatives

Color and Visual Presentation

Review:

• Text contrast

• Link contrast

• Button contrast

• Focus indicators

• Error indicators

• Information conveyed through color

Forms

Verify:

• Labels are associated with controls

• Instructions are understandable

• Required fields are identified

• Errors are clearly communicated

• Users can correct errors

• Keyboard users can complete the entire process

Structure and Navigation

Check:

• Page titles

• Heading hierarchy

• Landmarks

• Navigation consistency

• Link descriptions

• Reading order

Multimedia

Review videos and audio for:

• Captions

• Transcripts

• Audio descriptions where applicable

• Accessible controls

Assistive Technology

Test important user journeys with technologies such as:

• NVDA

• JAWS

• VoiceOver

• TalkBack

Why Automated Testing Should Not Be Your Only Check

Automated accessibility testing is useful for identifying detectable technical problems quickly.

It can help find issues such as:

• Missing alternative text

• Certain contrast failures

• Missing labels

• Some ARIA problems

• Certain markup errors

But automated testing cannot determine whether an experience is genuinely usable.

For example, a tool may confirm that an image has alternative text but cannot reliably determine whether the description is meaningful in context.

Similarly, an automated tool may identify a button but cannot fully assess whether the button's behavior makes sense for someone navigating with a screen reader.

For this reason, an effective compliance program combines automation, manual testing, and assistive technology evaluation.

Should High-Risk Websites Be Tested More Frequently?

Yes. 

Organizations should consider more frequent testing when their websites:

• Handle financial transactions

• Provide healthcare-related services

• Serve government or public-sector users

• Process applications

• Provide educational services

• Have complex customer portals

• Change frequently

• Depend heavily on interactive functionality

High-traffic websites and platforms with frequent releases may benefit from accessibility testing throughout the development lifecycle rather than relying on periodic audits.

What Happens If You Find Accessibility Issues?

Finding an accessibility issue does not mean the audit has failed. The purpose of testing is to identify barriers so they can be addressed.

A practical remediation process includes:

1. Document the Issue

Record where the problem occurs and what users may experience.

2. Map It to the Relevant WCAG Criterion

Connect the finding to the applicable accessibility requirement.

3. Prioritize the Issue

Consider user impact, business importance, and whether the issue blocks an essential function.

4. Remediate

Provide developers with actionable instructions for addressing the problem.

5. Validate the Fix

Retest the affected functionality to confirm the issue has actually been resolved.

6. Monitor for Regression

Make accessibility testing part of future development and release processes.

A Practical Accessibility Testing Schedule

There is no single schedule that works for every organization, but the following approach provides a useful starting point:

Organizations should adjust this schedule according to their risk profile, website complexity, release frequency, and applicable requirements.

Build Accessibility Into Your Development Process

The strongest accessibility programs do not treat testing as a separate project.

Instead, accessibility becomes part of:

• Product planning

• UX design

• Development

• Content creation

• Quality assurance

• Release management

• Procurement

• Governance

This helps organizations identify issues earlier and reduces the cost and effort associated with fixing them later.

For enterprise organizations, an accessibility governance program can establish who is responsible for testing, remediation, documentation, and ongoing monitoring.

Conclusion

Running an ADA website compliance checklist once is not enough to maintain accessibility over time. Websites change continuously, and each redesign, feature release, content update, and third-party integration can introduce new barriers.

For many organizations, an annual comprehensive assessment combined with ongoing testing during development and after significant changes provides a stronger approach. Higher-risk or frequently changing digital environments may require more frequent testing.

Most importantly, accessibility should become part of everyday digital operations rather than a last-minute compliance exercise.
