The most common WCAG failures on higher education websites are low color contrast, missing alt text, unlabeled form fields, keyboard traps, and skipped heading levels. Many of them pass an automated scan, because a scanner can confirm that an element is present but not that it works for someone navigating keyboard or screen reader
For a prospective student using a screen reader, a missing form label isn’t a technicality — it’s the difference between submitting a financial aid application and giving up and calling the office, if they even know to call. A keyboard user who hits a trap in a navigation menu doesn’t file a ticket explaining why; they just leave the site and, if the process was required, they leave the institution’s pipeline entirely. These failures decide who gets through the front door of your website and who doesn’t, long before anyone runs a compliance audit.
Most WCAG-failure roundups name the criterion a site violates and stop there. What actually helps a web team is knowing which of these an automated scanner already flags for you, and which ones need a person testing with a keyboard and a screen reader — because that split is what determines whether your remediation plan can lean on tools alone or needs manual review built in.
What are the most common WCAG failures on higher education websites?
These twelve account for most of what we find in a first-pass audit, ranked roughly by how often they appear.
| Failure | WCAG success criterion | Fix |
| Text and background contrast below 4.5:1 | 1.4.3 Contrast (Minimum) | Check with a contrast tool; adjust the foreground or background color to meet the ratio for body text |
| Form fields with no associated label | 1.3.1 / 4.1.2 | Pair every input with a <label> element or an aria-label |
| Keyboard traps or unreachable menus | 2.1.1 / 2.1.2 | Confirm every interactive element can be reached and exited using only a keyboard |
| Heading levels skipped or used for styling only | 1.3.1 Info and Relationships | Use real H1–H6 tags in order; don’t skip levels to change font size |
| Links that only say “read more” or “click here” | 2.4.4 Link Purpose | Write link text that makes sense out of context, or add an aria-label |
| No visible focus indicator when tabbing | 2.4.7 Focus Visible | Don’t remove the default outline in CSS; style a clearly visible focus state instead |
| Linked PDFs that were never tagged | 1.1.1 / 1.3.1 | Route documents through the same accessible-document workflow as the rest of the site before publishing |
| Auto playing video or audio with no pause control | 1.4.2 Audio Control | Add a visible stop or pause control, or remove autoplay entirely |
| Data tables with no header markup | 1.3.1 Info and Relationships | Use real <th> elements with scope attributes instead of bold text |
| Form errors shown only in red text | 1.4.1 Use of Color / 3.3.1 | Pair color with text or an icon that names the actual error |
| Inaccessible third-party widgets (chat, booking, payment) | Varies by widget | Request an Accessibility Conformance Report before embedding, and test the widget itself |
Which of these can an automated scanner catch on its own?
Roughly half. Automated scanning reliably detects the presence of a required attribute — an alt tag exists, a contrast ratio is measurable, a label element is present — but it can’t judge whether the content behind that attribute is actually correct or usable.
| A scanner usually catches | A person usually has to catch |
| Missing alt attribute | Whether the alt text is actually meaningful |
| Contrast ratio below threshold | Whether a focus indicator is visible in practice |
| Missing form label element | Whether the label text matches the field’s purpose |
| Heading level skipped | Whether a keyboard trap exists in a specific menu |
| Missing table header element | Whether a third-party widget is itself accessible |
Why do the same failures keep reappearing after a redesign?
Because a redesign usually changes the visual template, not the underlying build process that let these failures in the first time. Fixing the twelve failures above on the current site doesn’t prevent a new content editor, a new page builder block, or a new vendor widget from reintroducing the same problems six months later.
| Symptom | Why it happens | What works |
| New pages ship with the same contrast or label failures | No accessibility check in the publishing workflow itself | Add an automated check to the CMS publish step, not just an annual external audit |
| A new vendor widget fails on day one | Procurement didn’t ask for an ACR before signing | Require a current Accessibility Conformance Report before any new widget goes live |
| Fixes hold on the homepage but not on department sites | Departments use their own templates or page builders outside central IT’s review | Extend testing and training to every team publishing pages, not just the central web team |
Does ADA Title II require fixing these on a higher education website?
Yes, for most public colleges and universities. ADA Title II compliance requires WCAG 2.1 Level AA for web content by April 26, 2027 for institutions above the DOJ’s population threshold — which effectively covers nearly all public higher education — and April 26, 2028 for smaller entities. These twelve failures map directly to specific success criteria an auditor will check first.
What should a website team fix first?
1 Run an automated scan across your top-trafficked templates, then manually test the same templates with a keyboard alone and with NVDA or Voice Over.
2 Prioritize failures on pages tied to a required process: admissions, financial aid, registration, and course enrollment, since those are the pages where a failure blocks someone from completing something they need to do.
3 Fix contrast and alt text sitewide first — they’re usually the fastest to remediate, affect the most pages, and are the two failures a WCAG auditor checks within the first few minutes of any review.
4 Get a written Accessibility Conformance Report (ACR) from any third-party widget vendor before the next contract renewal, and put a retest clause in the contract for future updates.
If your team needs an outside read on which of these twelve are present on your own site, ContentA11Y is an accessibility testing company that combines automated scanning with manual keyboard and screen-reader testing, and maps every finding to the WCAG success criterion an auditor would cite rather than handing back a bare pass/fail score. We’ll test a handful of your highest-traffic pages at no cost and tell you which of these twelve failures are actually present before you scope a full engagement.
