CHECKING Third-PARTY MATERIALS FOR ACCESSIBILITY

How do I check Third-party materials for accessibility and remediate them if needed?

If third-party materials are found to be inaccessible, it is strongly recommended that alternate accessible content be used. It can be costly and time consuming to remediate inaccessible documents and media (video/audio) created by a third-party. However, if third-party content must be used, it must also be made accessible.

  1. Contact the content owner to ask for an accessible copy.
  2. If the owner does not have an accessible copy available, ask for permission to make the content accessible. (If the owner does not give you permission or you do not receive a response to your request, you must still have an accessible version of the content available for persons with disabilities.)
  3. With permission, remediate the inaccessible content. If you have attempted but are unable to get permission to remediate the inaccessible content from the owner, please email the Accessibility Coordinator at [email protected].

You can download checklists to verify the accessibility of types of materials: Presentations Accessibility Checklist, Multimedia Accessibility Checklist, and Document Accessibility Checklist.

What do I do if content can’t be made accessible?

If you find inaccessible online content and determine it can’t be fixed, you must provide an equivalent, alternate solution. Use the Accessibility Plan Template to document the accessibility limitations and to specifically identify the alternate resources, materials, etc. you plan to use in order to ensure that all students have full access to your online content.

TESTING AND CONVERTING SCANNED PDFS

This how-to guide shows how to test and convert scanned PDF documents. Because scanned pdfs are not accessible, users will specifically learn how to use the Optical Character Recognition (OCR) process to convert a scanned pdf to an accessible, searchable pdf.

Why is it important?

Scanned pdfs are essentially images of text, and cannot be read by a screen reader. This makes scanned pdfs completely inaccessible for users who are visually impaired.

Who benefits?

Users who are visually impaired benefit the most because they will have access to the information in the pdf.

How-To Guide: Testing Your PDF

Open

Open the PDF document with Adobe Reader.

Highlight Text

Select and highlight the text.

Read Out Loud

Test the text to see if it can be read aloud to you.

  • Go to Adobe Readers’ View menu.
  • Select Read Out Loud > Activate Read Out Loud.

Listen

  • Go back to View > Read Out Loud.
  • Click Read this page only or Read to the end of the document.
  • Listen to the document.
    • Does it read all text in the document?
    • Does it read the entire document in logical order?

How-To Guide: Converting Your Scanned PDF

Optical Character Recognition

For scanned documents, complete the Optical Character Recognition (OCR) or Text Recognition process to see if it can be read aloud.

  • In Adobe Acrobat Pro, choose Tools > Enhance Scans > Recognize Text > In This File.
  • Then adjust Pages and Language, and click Recognize Text.
    • Creates a layer of text in your PDF that can be searched or copied/pasted into a new document.
    • Allows text to be readable by a screen reader.
  • Use the Read Aloud feature to make sure it is readable.

Alt Text

If images, photos, diagrams, etc. are included in the document, add alt text or captions to explain the key message in the images.

  • Screen readers do not read/recognize any images if alt text is missing.
  • Go to Tools > Accessibility > Reading Order.
  • Reading Order window will be displayed; alt text will be shown near image.

Adobe Accessibility Checker

Use the Adobe Accessibility Checker to check for and fix any additional accessibility issues.

USING THE ADOBE ACCESSIBILITY CHECKER

What will be learned?

Learn how to check accessibility of PDFs using Adobe’s built-in Accessibility Checker. The checker makes sure a document is not an image-only PDF, contains tags to help screen readers, has a logical reading order, has a tab order that parallels the document structure, and has alternative text for images and figures.

Why is it important?

Using the Accessibility Checker allows you to find areas of your PDFs that are not accessible to all audiences. The accessibility report contains links to tools and documentation that can help you fix problems in your document.

Who benefits?

Making PDFs accessible benefits not only users with vision and mobility impairments but can also benefit users without disabilities. For example, the document structure that enables a screen reader to read a PDF out loud also enables a mobile device to display the document on a small screen. Similarly, the preset tab order of an accessible PDF form helps all users, not just users with mobility impairments, fill the form more easily.

How-To Guide: Adobe Accessibility Checker

Note: If there are numerous errors found in your Adobe document after using the accessibility checker, and reformatting is necessary, you may want to consider converting it to an MS Office document. It is often easier to reformat documents in MS Office first and convert it to a PDF second.

Open

Open the PDF document with Acrobat Pro.

Tools

Click on the Tools tab at the top of the screen.

Scroll down and click on the Accessibility icon.

Full Check

The Accessibility Toolbar will open to the right of your document.

Click Full Check to start the Accessibility Check.

Start Checking

In the Accessibility Checker Options dialogue box, select your choices.

  • We recommend leaving the default Checker Options selected to ensure you’re checking for the widest variety of accessibility issues.

Click Start Checking.

Review Results

Review the results in the Accessibility Checker panel on the left of your document.

Clicking on the arrow next to the category (Document, Page, Content, etc.) shows what was checked and whether it passed, failed, or needs to be manually checked.

Fix

Right-click (Windows) or control-click (MacOS) on one of the failed options for a menu that will allow you to fix the issue, skip the issue, or have the issue explained.

  • If you choose Fix, Acrobat will either fix the item automatically or display a dialogue box prompting you to fix the item manually.

What will be learned?

This how-to guide, developed by Instructure, will teach users how to check that Canvas pages are accessible to all users.

Accessible Canvas pages mean that all users will have access to your information. Also, planning for accessibility during the design phase of a course is less time consuming than remediating a course after a user has found it to be inaccessible.

Who benefits?

All users benefit, but users with disabilities benefit the most. Course designers also benefit from not running the risk that the course has to be remediated because a student reports that it is inaccessible.
