How we test: methodology and tools

Conformance is a measured result, not an opinion. Here is the methodology and the tooling behind every engagement.

The methodology

Testing follows the U.S. Department of Homeland Security Trusted Tester for Web methodology — a repeatable, criterion-by-criterion process the federal government uses to evaluate Section 508 conformance.

The tools

Automated coverage uses axe-core, the open-source engine maintained by Deque. Open-source tooling keeps results transparent and reproducible. Automation is the first pass, never the last.

Automated vs. manual

Automated checks reliably catch contrast, missing alt text, missing labels, and document-language issues. They cannot confirm keyboard operability, logical focus order, meaningful reading order, or whether a screen reader conveys the page. Those require manual and assistive-technology evaluation — and they are where most real-world barriers live.

The complimentary scan

A free automated WCAG 2.1 AA check of a single homepage. It is a first look that surfaces the issues a demand letter would likely cite — not a full audit.

On VPATs and conformance reports

A VPAT / Accessibility Conformance Report is completed and signed by the evaluator. Only automated criteria are pre-filled; conformance claims are never auto-generated, because a false attestation is a liability, not a deliverable.
