3.3.5: Help
What it means
Context-sensitive help is available for complex tasks — instructions, tooltips, chat, or dedicated help links. AAA expects proactive help, not only error messages after failure.
Long forms and unfamiliar processes benefit most.
How to fix it
- Link to relevant help articles beside complex questions.
- Offer live chat or phone on high-stakes flows.
- Provide examples and tooltips before users submit.
- Keep help text updated when forms change.
Quick examples
- Good: Tax form fields link to plain-language help on each deduction type.
- Bad: A 40-field grant form has no instructions until submission fails.
- Good: Insurance quote tooltips explain jargon before users choose options.
- Bad: Help content exists but is buried three levels deep in the site.
