Introduction

The purpose of the PDF Accessibility Checklist is to support Employment and Social Development Canada (ESDC) PDF document developers ensure that accessibility compliance meets the Web Content Accessibility Guidelines (WCAG) 2.1 standards. Please note that the checklist only contains WCAG criteria that are related to the most common errors identified in PDF documents.

We established a list of tools and resources to help developers verify their document accessibility, as well as the PDF Accessibility Checklist that identifies 27 success criteria that are pertinent to PDFs.

• 3 – The language of a passage, phrase, or word that differs from the language of the PDF is specified as the correct language.
• 4 – Pages are appropriately bookmarked for easier navigation.
• 5 – There are running headers and footers as needed so users know where they are in the PDF at all times.
• 6 – Pages are clearly marked. Eg. 1 – 2 – 3 / A – B – C etc.
• 7 – The reading order of the PDF is correct. Screen readers read the contents in the logical order.

• 8 – Using the tab key, the user is able to navigate through the PDF for all input fields, and links, in the correct order.
• 9 – Page headings with subheadings are included as needed.
• 10 – Tables are correctly tagged so that they are recognized by assistive technology.
• 11 – Lists of various related items are tagged as lists and list items correctly.
• 12 – Visuals that do not add any additional value to the content, and contain no text are marked as decorative and ignored by screen readers.
• 13 – Visuals include a written description of the visual for context. The alternative text of the visual explains where the description is located. Visuals that do not contain written descriptions in the body of the PDF have descriptive alternative text.
• 14 – When using colours, shapes, or visual aids to convey a message, there are other written descriptors to get the message across.
• 15 – Text, and images of text have a contrast ratio of at least 4.5:1; except for large text (above size 14 bold, or above size 18) which requires a contrast ratio of 3:1. This will ensure the colour scheme is optimal for the visually impaired and/or colour blind.
• 16 – Links are clearly marked and contain descriptive text.
• 17 – Form input options are clearly marked and described.
• 18 – Radio buttons allow for one selection – these are clearly marked as circles.
• 19 – Checkboxes allow for multiple selections – these are clearly marked as squares.
• 20 – Links are clearly marked with blue, underlined text.
• 21 – Form controls are properly displayed and indicated on the form for users to easily access and identify.
• 22 – All fields have a proper name, role, and value attached for users.
• 23 – All text fields have associated descriptive text. This allows assistive technology to recognize and understand the different form fields.
• 24 – When a user has failed to input information correctly in a field, there is a clear error indicator that visually and auditorily informs the user of the error, how to correct the error, and properly fill out the field.
• 25 – The submit button is clearly marked so that users know

  how to submit the form they are filling out.

• 26 – Best Practice: when using an acronym ensure that the first time it is mentioned in the PDF that it is fully defined. Eg. Employment and Social Development Canada (ESDC)
• 27 – Best Practice: the font is sans serif and commonly used. (for enhanced visual legibility)
