- Level: AA
- Guideline: 3.2 Predictable
- Principle: 3 Understandable

## What it is

Navigational mechanisms that are repeated on multiple web pages within a set of web pages occur in the same relative order each time they are repeated, unless a change is initiated by the user.

## How to test

- Check: Navigational mechanisms that are repeated on multiple web pages within a set of web pages occur in the same relative order each time they are repeated, unless a change is initiated by the user.
- Use the sufficient techniques below as acceptable methods when applicable.
- Confirm none of the common failures apply.

## Sufficient techniques (W3C)

- G61: Presenting repeated components in the same relative order each time they appear

## Advisory techniques (W3C)

- PDF14: Providing running headers and footers in PDF documents
- PDF17: Specifying consistent page numbering for PDF documents

## Common failures (W3C)

- F66: Failure of Success Criterion 3.2.3 due to presenting navigation links in a different relative order on different pages
