On April 24, 2024, the United States Department of Justice (DOJ) Civil Rights Division published a final rule to its update for Title II of the Americans with Disabilities Act (ADA).

In it, the DOJ stipulates that government entities must meet the World Wide Web Consortium (W3C®) technical standards set forth in the Web Content Accessibility Guidelines (WCAG) Version 2.1, Level AA. As explained in the DOJ Fact Sheet, Title II is specific to state and local programs that provide the public with services, programs, or other activities. As such, they are required to follow accessibility requirements as set forth by the DOJ Civil Rights Division as this helps to ensure equal access to these public goods. Described in the Fact Sheet as the final rule, it applies to the accessibility of web content and mobile apps. Depending on the size of population served, government agencies have 2 to 3 years to come into compliance—with the deadline either April 2026 or April 2027.

For a quick-glance of the rule, please see Fact Sheet: New Rule on the Accessibility of Web Content and Mobile Apps provided by State and Local Governments.

Why Accessibility is Important

A statistic the W3C® shares in their Video Introduction to Web Accessibility and W3C Standards is that 15-20% of the population are people with disabilities, or—to frame it another way—there are more than 1-billion people with disabilities. Additionally, they cite The UN Convention on the Rights of Persons with Disabilities defining access to information is a human right.

How This Relates to Museums

Full and equal access to services, programs, and other government-offered activities must be supported—in this case, online. This includes museum collection offerings published online via a Collections Management System (CMS). Even if your museum isn’t a government entity, it is considered best practice (and the ethical thing to do) to meet these federally outlined requirements. In addition to offering equal access and servicing a decent size of the population, the museum’s online content and community of users also benefit in the following ways:

  • Increases collections online to all online constituents.
  • Improves the user experience for everyone.
  • Fulfills requirements from granting agencies and foundations.
  • Supports search engine indexing and discoverability of collections content online.

WCAG is the International Standard

When considering the accessibility of museum collections content online, the most often referenced best practices are the WCAG. WCAG was created by the Web Accessibility Initiative at the WC3®, and is an international standard (ISO 40500).

A Note on WCAG Versions and Ratings

WCAG 2.1 covers a wide range of recommendations for making web content more accessible. It was first published June 2018 and last updated September 2023. There is just one more recent version available currently: WCAG 2.2, published October 2023. WCAG 3 drafting is underway, though it will reportedly be a few years before it’s ready. The current set of WCAG standards use a 3-tier ranking of A (good), AA (better), and AAA (best).

The Purpose of the WCAG

WAI offers freely available guidance, success criteria, examples, and resources for evolving web content into an improved form of accessibility. WAI states that:

Following these guidelines will make content more accessible to a wider range of people with disabilities, including accommodations for blindness and low vision, deafness and hearing loss, limited movement, speech disabilities, photosensitivity, and combinations of these, and some accommodation for learning disabilities and cognitive limitations; but will not address every user need for people with these disabilities. These guidelines address accessibility of web content on desktops, laptops, tablets, and mobile devices. Following these guidelines will also often make Web content more usable to users in general.

While our use regarding these accessibility standards will be focused on the public museum collections content as published by the museum CMS, these standards can be used by museums to evaluate any of their online content.


Over the next few weeks, we’ll review these broadly applicable standards and explore how they may relate to the CMS presentation of museum collection content online. This will include consideration of the CMS navigation, the presentation of data and collection information, and the accessibility of digital assets (digital surrogates of the collection). Next week begins with Principle 1: Perceivable.
