Access Restrictions
Are there any access restrictions on the PDF, such as password protection?
Default Language
Is the natural language of the PDF document specified?
Document Title
Does the PDF have a meaningful and descriptive title (not just a file name)?
Bookmarks

Content Reflow
When Reflow mode is activated, does all the content reorganize naturally in a single, easy to read column?
Read Out Loud
When Read Out Loud is activated, does all the content get read correctly and in the right order?
Semantic Structure
Is content organized consistently using semantically and correctly structured tags/markup?
Tabbing Order
Can the document be navigated in a logical order that is consistent with the meaning of the content?
Informational Images
Does the text alternative provided for every informational image convey the same meaning or purpose as the image?
Decorative Images
Are purely decorative images marked up as artifacts, so screen readers can safely ignore them?
Meaningful Hyperlinks
Is hyperlink text marked up using Link annotations and is the purpose of that text meaningful?
Page Numbering
Does page numbering differ from the numbering displayed in the viewer page controls?
Running Headers & Footers
Are running headers and footers provided consistent with existing section headings?
Data Tables
Are the tables marked up properly and are header cells and data cells explicitly associated?
Form Fields
Can assistive technologies gather information about and interact with form controls?
