What Is WCAG, and Why It Matters for Local Government Websites

WCAG isn’t new.

The Web Content Accessibility Guidelines have shaped digital accessibility standards for years. Yet for many local government communications teams, WCAG can still feel unclear, technical, or disconnected from day-to-day responsibilities.

And that gap affects residents.

Communications professionals in local government publish the very content WCAG governs, including PDFs, forms, meeting agendas, reports, and website content. When that content is not accessible, residents may be unable to access services, participate in meetings, or review important information independently.

This post breaks down what WCAG is and why it matters for local government websites. It explains how the standards work, what the different conformance levels mean, and how WCAG applies to the content communications teams manage every day.

What’s WCAG and Why Does It Matter for Local Governments?

WCAG stands for the Web Content Accessibility Guidelines. It is a set of internationally recognized standards for making digital content accessible to people with disabilities.

WCAG is developed and maintained by the World Wide Web Consortium (W3C) through its Web Accessibility Initiative. The W3C publishes the official WCAG documentation and supporting guidance. The WCAG 2 Overview and related documents are available through the W3C Web Accessibility Initiative.

While laws such as the Americans with Disabilities Act (ADA) require state and local governments to provide equal access to services, whether in physical spaces or online, WCAG explains how to meet that obligation in the digital environment.

In other words:

• The ADA establishes the civil rights requirement.
• WCAG provides a technical roadmap.

Understanding the Four WCAG Principles (POUR)

WCAG is organized around four core principles. Together, they define what accessible digital content must achieve. Content must be perceivable, operable, understandable, and robust.

These principles, often simply referred to as POUR, directly impact the PDFs, forms, meeting materials, and webpages that communications teams publish every day.

Perceivable

Perceivable means information must be perceptible to people using only one of their senses, so they understand all related content.

This goes beyond simply making content visible. For someone using a screen reader, images require alternative text. Headings must be structured correctly so the page can be navigated logically. Text needs sufficient color contrast to remain readable for residents with low vision.

When these elements are missing, the barrier is immediate. A budget chart uploaded as an image without description may look complete to one resident and blank to another. Headings styled visually but not properly tagged may appear organized, yet screen reader users cannot move through the document efficiently.

If content cannot be perceived, access stops before it begins.

Operable

Operable means residents must be able to navigate and interact with content using different methods and tools.

Not every resident uses a mouse. Some rely entirely on a keyboard. Others use assistive technologies to navigate forms and interactive elements.

For instance, if an online permit form cannot be completed using keyboard navigation, the process effectively excludes certain residents. If focus indicators are missing, users may not know where they are on a page. If a session times out too quickly, a resident may lose progress before completing a submission.

In each case, the issue is not whether the information exists. It is whether residents can successfully interact with it.

Understandable

Understandable means residents must be able to make sense of the content and know what to do next.

For communications teams, this often shows up in forms, applications, and service pages. Instructions need to be clear. Navigation labels need to match the content they lead to. Error messages must explain what went wrong and how to fix it.

For example, if a resident submits a permit application and receives an error message that simply says, “Invalid entry,” the barrier is not visual. It’s merely informational. Without clear guidance, the resident may not be able to complete the process independently.

When content is confusing, inconsistent, or overly complex, it can create barriers for residents.

Robust

Robust means content must work reliably with assistive technologies, now and in the future.

This is where formatting decisions matter. A document may look polished on screen but fail behind the scenes.

For example, uploading a scanned, image-only PDF of meeting minutes may appear compliant because it’s available online. But if a screen reader cannot interpret the text, the content is not accessible in practice. If headings are not properly tagged, screen readers cannot convey the structure. If tables lack header associations, the data may be read in the wrong order. If a PDF is scanned as an image, the text may not be readable at all.

Robust content relies on proper structure, machine-readable text, and accessible documents. Without that foundation, even well-written content cannot be reliably accessed by residents who depend on assistive technology.

WCAG Levels Explained: A, AA, and AAA

WCAG includes three levels of conformance: A, AA, and AAA. The three levels are designed to progressively enhance accessibility for users with disabilities.

Level A

Level A is the foundational level of WCAG.

It addresses the most basic accessibility barriers that can prevent residents from accessing content at all. But on its own, it does not represent comprehensive accessibility for local government websites, nor does it meet the U.S. Department of Justice’s (DOJ) rule on web accessibility.

Level AA

Level AA builds on Level A and addresses barriers that commonly affect how residents experience and complete tasks online. WCAG 2.1 Level AA is widely recognized as the benchmark for local governments and special districts. The DOJ establishes WCAG 2.1 Level AA as the technical standard under Title II of the ADA. For more, the ADA’s Fact Sheet outlines this requirement.

At this level, accessibility moves beyond removing obvious blockers. It focuses on usability and clarity. It includes requirements related to color contrast, form labels, error identification, and navigation structure.

In practice, Level AA determines whether a resident can successfully complete a process, not just access it. For example, a form field without a programmatically associated label may appear clear visually but prove confusing when accessed by a screen reader.

Level AAA

Level AAA represents the highest level of conformance. It includes all Level A and AA requirements and aims to make content usable by the widest possible audience.

However, the W3C notes that it is not always possible to meet all Level AAA success criteria for entire websites due to cost, complexity, and technical limitations. That’s why WCAG 2.1 Level AA remains the realistic and widely recognized benchmark for state and local governments.

Using WCAG as an Ongoing Accessibility Strategy

If accessibility cannot be solved with a one-time remediation effort, it must be built into how content is created and published.

WCAG provides the framework. The challenge is operationalizing it.

An effective accessibility strategy moves beyond reacting to audits or complaints. It establishes clear standards and repeatable processes that apply every time new content is published. That typically includes:

• Defined publishing standards aligned with WCAG, so staff know what is required before content goes live
• Training for employees who create documents, upload PDFs, or manage webpages
• Review of workflows for high-impact content, such as forms, public meeting materials, and service applications
• Tools that help teams maintain accessibility consistently, even as content volume grows

How to Simplify Web Accessibility Compliance

Web accessibility spans templates, navigation, forms, multimedia content, and document libraries. As digital services expand, maintaining compliance becomes an ongoing operational responsibility.

CivicPlus helps local governments strengthen web accessibility through a comprehensive approach. By combining automated fixes, expert audits, continuous monitoring, and accessible documents, municipalities can move from reactive remediation to proactive compliance.

If you are unsure how your website measures up to WCAG standards, the first step is visibility.
