High-level overview of accessibility referentials supported by CheckFox.

What a referential is

A referential is a structured set of accessibility criteria with associated conformance levels. CheckFox lets each audit pick exactly one. Specific criterion text and tests live in the database, not in this file.

Referentials in CheckFox

WCAG 2.2

The international baseline. Maintained by the W3C. Levels A, AA, AAA. The starting point for almost all accessibility law worldwide.

Use when: international audience, no specific national obligation, or as a foundation for national referentials.

RGAA 4.1

The French national referential. Built on WCAG but adds operational test procedures and slightly different organization.

Use when: auditing a French public-sector service or a service subject to French obligations.

RAWeb 1.1

The Luxembourg national referential. Aligned with EN 301 549 and WCAG. Required for Luxembourg public-sector services.

Use when: auditing a Luxembourg public-sector service or a service subject to LU obligations.

Choosing a level

A — minimum. Rarely sufficient on its own; some legal regimes require it as a floor.
AA — the de facto legal standard in EU and US contexts. Default choice for most audits.
AAA — aspirational. Some criteria at AAA are intentionally not required for full conformance because they cannot be met by all content types.

Most legal regimes (EU public sector directive, US Section 508, LU and FR national laws) target Level AA.

Choosing a referential

If both a national referential and WCAG apply, the national referential governs. Audit against the national one and rely on its mapping to WCAG for international comparability.

Multiple referentials

A single audit picks one referential. If a service must declare conformance against multiple, run separate audits per referential.

Where the criteria text lives

In the database, not in this file. The AI assistant fetches specific criterion text by ID on demand. Asking "what does WCAG 1.4.3 say?" triggers a SQL lookup, not a markdown read.
