One of the tools we use to certify titles is Ace by DAISY, which checks for basic accessibility features. Ace is a free, open-source tool that is being widely adopted by publishers and conversion vendors. Built on top of HTML checking technology, Ace reviews between 20% to 30% of the EPUB file. The rest of the file must be manually inspected.
Using Ace by DAISY is an important first step in reviewing basic accessibility features, but it will not check many features that schools and universities require. Benetech’s Global Certified Accessible (GCA) program offers publishers a more in-depth review of their content, covering all accessibility features that can be implemented today and going beyond Ace‘s capabilities. The GCA program also provides detailed feedback on files reviewed, which includes an overall accessibility score, an overview of accessible features, a detailed summary of our findings, and suggestions for remediation.
