Hi Barbara,

Working for a consulting company (The Paciello Group) I have a little
insight.

If you have a lot of pages for all your sites and most pages in a site have
similar templates, content, etc. I think a automated scan will help find
issues with the templates or common content (header, navigation, footer,
etc.) that may not be part of the manual review.

The automated scan will generally find 1000's of issues, reporting the same
exact issue on each page where it exists. This can help you get more bang
for your buck and Identify common issues across a large number of pages.
Having said that, automated tests are limited to what they can automatically
test so they may miss issues or have false positives/negatives.

In terms of re-review, this can be helpful to ensure that your developers
correctly addressed any issues discovered during the manual review. This
requires that fixes have been completed other wise the re-review will report
the same unfixed issue. A re-review can be important if you are documenting
your conformance for legal or business reason.

Often, when my company is contracted to do a re-review a VPAT (Voluntary
Product Accessibility Template) is part of that work and documents the
accessibility of the "product" at that point in time.

So both options can be worth the money, but you will need to decided that.

Hopefully this helps.

Subject: [WebAIM] value of re-testing after manual accessibility audit

Hello, could anybody please help with some advice? I am looking into third
parties to do an accessibility audit of our sites. We are a charity and we
have multiple domains and sub-domains, so it can be potentially expensive.

The companies I contacted quoted us on different variables, one of which is
re-testing after the manual audit check for fixes or new problems created by
the fixes.

Another variable is automated testing on top of the manual as a safety net
in case something has been missed by the manual one.

How much value is there in re-testing? Is it risky to skip this step?
Same for automated testing. How much value, if you have done a proper manual
one?

Many thanks,
Barbara
