Frequently Asked Questions
What is an accessibility glossary?
An accessibility glossary is a list of the terms used in digital accessibility, from standards such as WCAG and EN 301 549 to laws, assistive technologies and testing methods, each explained in plain language. Ours has 200 terms, written and reviewed by the web accessibility experts who run our audits.
What is the difference between WCAG, the ADA and Section 508?
WCAG is the W3C’s technical standard for accessible web content. The ADA is a US civil rights law: the Department of Justice’s Title II web rule requires state and local governments to meet WCAG 2.1 Level AA by April 26, 2027 (populations of 50,000 or more) or April 26, 2028 (smaller entities and special districts). Section 508 covers US federal agencies, and its standards incorporate WCAG 2.0 Level AA. See ADA Title II, ADA Title III and Section 508 in the glossary.
What is the difference between a VPAT and an ACR?
A VPAT (Voluntary Product Accessibility Template) is the blank reporting template published by the Information Technology Industry Council. When it is completed from real testing, the result is an Accessibility Conformance Report (ACR). We write ACRs from hands-on testing through our VPAT and ACR documentation service.
What does WCAG 2.2 Level AA mean?
WCAG 2.2 became a W3C Recommendation on 5 October 2023. It adds nine success criteria to WCAG 2.1, such as Target Size (Minimum) and Accessible Authentication, and removes 4.1.1 Parsing (W3C: What’s New in WCAG 2.2). Level AA means a page meets every Level A and Level AA success criterion. It is the level most laws and contracts ask for.
How much does an accessibility audit cost?
Our packages are fixed prices: a one-hour technical consultation (audit walkthrough, developer Q&A or live issue review) is $100, a Quick Accessibility Audit is $500, and a complete audit is $2,000, including the Shopify Accessibility Audit. Remediation and VPATs are quoted after we see the findings. See accessibility audit pricing for what each package includes.
Can an automated scanner or overlay make my website compliant?
No. Automated tools cannot check every WCAG requirement, which is why the W3C’s guidance on evaluation tools says to combine them with manual review. An accessibility overlay does not fix the underlying code either; read why in accessibility overlays and ADA lawsuits. Our audits pair scans with manual testing in NVDA, JAWS, VoiceOver and the keyboard.
Who writes and reviews these glossary definitions?
Our web accessibility experts. Reviews are led by founder Mohammad Shadab Saifi, who has 10+ years in digital accessibility and holds the IAAP CPACC, WAS and CPWA certifications. If a term on your audit report is unclear, book a $100 consultation and we will walk you through it.
I am new to accessibility. Where should I start?
Read WCAG and accessibility audit first, then the guide that fits your situation: audit cost, an ADA demand letter or the European Accessibility Act. When you want to talk it through, book a free 30-minute call. It is a first conversation to understand where you stand and scope a project. If you already have scan results or audit findings to go through with your developer, the $100 one-hour technical consultation is the better fit.
