Section 508 Procurement: What Must Be Accessible

A software purchase can create years of accessibility exposure. When a federal agency, contractor, or federally funded program adds a new platform, document library, learning tool, or WordPress component, Section 508 procurement is the point where accessibility requirements must become enforceable contract terms – not a promise to address issues after launch.

The revised Section 508 standards apply to information and communication technology, commonly called ICT. That scope reaches far beyond a public homepage. It can include websites, web applications, software, PDFs, videos, support documentation, kiosks, mobile experiences, and internal systems used by employees. A procurement process that evaluates only a vendor’s marketing claims or a single accessibility statement leaves significant risk unresolved.

Why Section 508 Procurement Starts Before Vendor Selection

Section 508 requires federal agencies to provide accessible ICT to people with disabilities, unless an exception applies. For most web-related purchases, accessibility is not an optional product feature. It is a defined performance requirement that must be considered alongside security, privacy, cost, functionality, and support.

The revised standards incorporate WCAG 2.0 Level A and AA success criteria for applicable web content and software. Many organizations also use WCAG 2.1 or WCAG 2.2 as their operational benchmark because newer criteria address needs involving mobile use, touch targets, authentication, focus appearance, and other common user interactions. The exact requirement depends on the procurement, governing policy, and contract language, but the practical direction is clear: evaluate the actual experience, not just a high-level claim of conformance.

This matters especially for WordPress. A site may use an accessible theme while publishing inaccessible PDFs, adding uncaptioned videos, embedding third-party forms, or introducing faulty heading structures through ordinary editorial work. Procurement must account for the technology being purchased and the publishing process that follows.

Define Accessibility Requirements That Vendors Can Meet

Vague requirements invite vague responses. Language such as “must be accessible” signals intent, but it does not tell a vendor what evidence is required, which standards apply, how issues will be handled, or what happens after deployment.

Start by defining the ICT in scope. Identify public-facing pages, authenticated portals, downloadable documents, authoring interfaces, administrative screens, templates, plugins, integrations, and any content the organization will create after implementation. If a product will generate PDFs, send email, host training, or accept forms, those outputs and workflows should be evaluated too.

A useful solicitation separates three questions. First, which standards and criteria apply? Second, what accessibility documentation and test evidence must the vendor provide? Third, what remediation, support, and reporting obligations will continue through the contract term?

For web systems, specify the expected conformance target and require vendors to identify known exceptions at the criterion level. Also require an accessibility conformance report, often provided in the Voluntary Product Accessibility Template format. A VPAT can be valuable, but it is not a certification, a guarantee, or a substitute for testing. It is a vendor-provided disclosure that needs review.

The requirement should also address changes. Software updates, new templates, imported content, and third-party integrations can introduce barriers after acceptance. Procurement terms should establish notice requirements, remediation timelines, testing expectations, and a clear escalation path when an issue affects a critical task.

How to Evaluate a VPAT Without Treating It as Proof

A complete VPAT is a starting point for due diligence. Reviewers should look beyond the overall conclusion and examine the remarks for each applicable criterion. “Supports” without explanation provides little decision-making value. Stronger documentation describes how a feature was tested, identifies any exceptions, and explains the workaround or planned correction when support is partial.

Pay close attention to the functions users must complete. Can someone navigate entirely by keyboard? Are form errors announced clearly to screen reader users? Is visible focus present? Do headings, labels, tables, and status messages convey the correct information? Can a user complete authentication without being forced to solve an inaccessible puzzle or perform a cognitive function without an alternative?

A vendor may accurately report that its core application conforms while excluding customer-created content, implementation configurations, or third-party add-ons. That distinction is crucial for WordPress procurement. A plugin may be accessible in isolation while the theme, page builder, menu, PDF workflow, or embedded service creates barriers elsewhere on the site.

Ask for representative testing evidence rather than relying solely on a document. This can include testing methodology, browser and assistive technology combinations used, issue logs, sample reports, and demonstrations of critical user flows. Automated scans are valuable for detecting repeatable code-level failures at scale, but they do not replace manual testing of keyboard behavior, reading order, meaningful alternatives, and task completion.

Build Accessibility Into the Evaluation Process

Accessibility should carry real weight in the scoring model. If it is listed as a minor preference, price or feature volume can easily outweigh a product that creates avoidable barriers. For systems serving the public or supporting essential employee work, accessibility should be a pass-fail requirement for critical functions, with documented exceptions reviewed by the appropriate stakeholders.

A practical evaluation team often includes procurement personnel, the business owner, IT or security reviewers, web or application specialists, and an accessibility subject matter expert. People who manage content should participate when the purchase involves a content management system. They understand the daily realities that can undermine an otherwise accessible implementation.

During demonstrations, provide vendors with defined scenarios instead of asking whether their product is accessible. Request a keyboard-only completion of a common workflow. Ask the vendor to show error identification, document upload behavior, content authoring prompts, and administrative controls. Require the same demonstrations from each finalist so the comparison is meaningful.

Where possible, test a configured trial environment. This is particularly useful for WordPress websites because accessibility defects often emerge from the interaction between plugins, themes, custom code, and editorial practices. A staged test with representative content provides more useful evidence than a polished sales demonstration.

Contract Terms Should Cover Remediation and Accountability

Accessibility obligations should survive the award decision. A contract that requires conformance at signing but says nothing about patches, new releases, or discovered defects can leave the buyer paying to correct the vendor’s accessibility failures.

Include measurable remediation commitments. Severity definitions, response times, correction deadlines, reporting frequency, and acceptance criteria should be clear. A critical barrier that prevents a user from submitting an application or accessing required information needs a faster response than a minor visual inconsistency.

The agreement should define who owns remediation for configurable features and customer-created content. This is not always simple. A vendor may be responsible for the product interface, while the organization remains responsible for accessible documents and editorial choices. The right answer depends on the service model, but unclear responsibility is not an acceptable answer.

For WordPress projects, require the implementation plan to address theme modifications, custom templates, forms, menus, media, and existing PDFs. Also consider whether the organization needs ongoing reporting, content publishing controls, training, or remediation guidance. Accessibility is operational work, and the contract should fund the work required to sustain it.

Use Ongoing Scanning to Protect the Procurement Investment

Acceptance testing provides a snapshot. Websites change every week, sometimes every hour. New pages, contributor edits, plugin updates, and uploaded files can introduce failures after the original procurement review is complete.

A WordPress-native accessibility checker helps convert procurement requirements into a repeatable control. WP ADA Compliance Check scans published content and broader site elements, including theme files, custom post types, widgets, menus, PDFs, and linked pages. It evaluates issues against WCAG 2.1, WCAG 2.2, and Section 508 standards, then provides code-location details and remediation guidance so teams can act on findings rather than sort through generic warnings.

For organizations with distributed editors, publishing controls matter as much as audit reports. Catching missing alternative text, empty links, heading errors, and other detectable issues before publication reduces rework and helps prevent a compliant launch from degrading over time. Automation will not validate every accessibility requirement, but it can make continuous oversight far more practical.

Keep the Record, Not Just the Product

A defensible Section 508 procurement file documents the accessibility requirement, vendor representations, evaluation results, exceptions, risk decisions, contract remedies, and acceptance evidence. This record supports internal accountability and gives future teams a clear understanding of what was purchased and what obligations remain.

The strongest procurement process does not assume a VPAT ends the accessibility conversation. It establishes a standard of evidence, assigns responsibility, and gives the organization a way to detect and correct barriers as the technology evolves. That is how accessibility moves from a procurement checkbox to a controlled, maintainable part of digital operations.
