Questions · The VPAT® and the ACR
Which VPAT edition do we need: WCAG, 508, EU or INT?
Use the edition that matches the standard your buyer cites. ITI’s current version, 2.5Rev (April 2025), has four: WCAG for WCAG-based requests, including the ADA Title II rule; Revised Section 508 for U.S. federal agencies; EU for EN 301 549; and INT, which combines all three. The editions don’t all use the same WCAG version.
The four editions of VPAT® 2.5Rev
| Edition | Standards reported | WCAG version | Usual buyer |
|---|---|---|---|
| WCAG | WCAG 2.0, 2.1 and 2.2 | 2.2 (you may report 2.1 only) | Public universities, state and local governments, private companies |
| Revised Section 508 | Revised 508 Standards (36 CFR part 1194) | 2.0 | U.S. federal agencies |
| EU | EN 301 549 V3.1.1 and V3.2.1 | 2.1 | Public-sector buyers in the EU |
| INT | All of the above | 2.2 | Buyers in more than one of these markets |
ITI explains the difference: each edition carries the WCAG version built into its standard. The Revised 508 Standards incorporate WCAG 2.0 Level A and AA (36 CFR 1194, E205.4 and E207.2), and the EU edition’s EN 301 549 uses WCAG 2.1. ITI’s template lets a WCAG edition report drop the rows marked “2.2 only” when it reports on WCAG 2.1.
Three rules of thumb
- Federal agencies: GSA tells vendors to use the Revised Section 508 or INT edition, and says any VPAT® 2.x is acceptable.
- ADA Title II and the HECVAT: both name WCAG 2.1 AA, so the WCAG edition fits. Report Level A and AA for WCAG 2.1, or for 2.2; the W3C notes that content meeting WCAG 2.2 also meets 2.1.
- Several markets at once: the INT edition answers all three standards in one report.
How ACR Desk handles this
The WCAG edition is $1,490; the Section 508, EU and INT editions are $1,990, fixed, in five business days. Forward the buyer’s request with yours: the written quote names the edition it calls for, and why.
