Series: Creating Accessible Materials Training 4 of 4 Estimated Time: 10 Minutes Format: Video + Final Checklist

Creating Accessible Materials: The Learning Path

This final training brings together the Word, PowerPoint, and PDF modules. Use it to confirm that the exact files participants will receive are accessible, usable, accurate, and ready to share.

Training Video Coming Soon The video will demonstrate a final accessibility review of Word, PowerPoint, and PDF files before they are shared.

Have the exact file you plan to distribute available so you can complete the review while following the guide.

Overview

Accessibility checkers can identify many common problems, but they cannot determine whether alternative text is meaningful, whether content follows a logical reading order, whether captions are accurate, or whether instructions make sense to participants. A final review therefore includes both automated checking and human judgment.

Review the exact final file—not an earlier draft. Every edit, export, conversion, or replacement can introduce new barriers. When a problem appears in a PDF, return to the original Word document or PowerPoint presentation whenever possible, correct the source, and export the PDF again.

What You Will Learn

  • How to review the exact final version participants will receive.
  • How to run the built-in Accessibility Checker in Word and PowerPoint.
  • Why automated results must be followed by a manual review.
  • How to check structure, reading order, alternative text, links, tables, contrast, and media.
  • How to complete a basic PDF accessibility and usability review.
  • How to verify file names, permissions, links, and delivery before sharing.
  • How to decide whether a file is ready, needs revision, or requires additional support.

Before You Begin

Passing an automated accessibility check does not guarantee that a file is fully accessible. Automated tools may miss problems or identify items that still require human interpretation. Always complete the manual checks described below.

Step-by-Step Final Review

Review the Exact Final Version

Begin with the file participants will actually receive, open, download, or view during the seminar.

  1. Confirm that you are reviewing the most recent version.
  2. Save the file with a clear name and version date when appropriate.
  3. Remove outdated drafts from the sharing location.
  4. Open the file from the same location or link participants will use.
  5. Confirm that the file opens without an error, login problem, or missing resource.

Tip: A correctly reviewed file can still create a barrier if participants receive an older or inaccessible version by mistake.

Run the Built-In Accessibility Checker

Use the checker in the original Word document or PowerPoint presentation before reviewing the exported PDF.

  1. Open the final Word document or PowerPoint presentation.
  2. Go to the Review tab.
  3. Select Check Accessibility.
  4. Review all errors, warnings, and tips.
  5. Correct the issues that apply.
  6. Run the checker again after making changes.
  7. Save the corrected source file.

Tip: Read the explanation provided for each issue. Do not dismiss a warning only because the file looks correct visually.

Check Document and Slide Structure Manually

Confirm that the structure makes sense for someone navigating with assistive technology rather than only viewing the file visually.

  1. Confirm that Word documents use built-in heading styles in a logical order.
  2. Confirm that every PowerPoint slide has a meaningful title.
  3. Use real bulleted and numbered lists rather than manually typed symbols.
  4. Check that tables have simple structures and clear header rows.
  5. Review the reading order of slide objects and complex page content.
  6. Make sure repeated headers, footers, and decorative elements do not interrupt navigation.

Tip: Use Word’s Navigation Pane and PowerPoint’s Reading Order pane to experience the structure more directly.

Review Images, Charts, and Alternative Text

The checker can identify missing alternative text, but it cannot determine whether the description communicates the right information.

  1. Confirm that meaningful images, charts, maps, and diagrams have useful alternative text.
  2. Describe the purpose or takeaway—not every visual detail.
  3. Mark purely decorative images as decorative.
  4. Make sure charts and diagrams are also explained in nearby text or narration when needed.
  5. Confirm that image captions and alternative text do not contradict one another.
  6. Remove automatically generated descriptions that are inaccurate, vague, or irrelevant.

Tip: Ask whether a participant who cannot see the image would receive the information needed to understand the seminar content.

Check Readability and Visual Access

Review the material in the way participants are likely to use it: on a screen, in print, enlarged, or projected in a classroom.

  1. Confirm that body text and slide text are large enough to read comfortably.
  2. Check color contrast between text, graphics, and backgrounds.
  3. Make sure color is not the only way information is communicated.
  4. Look for crowded pages, dense slides, long paragraphs, and very small notes.
  5. Confirm that content remains readable when enlarged.
  6. Check that important information is not cut off or hidden.

Tip: View slides in full-screen mode and open documents at increased zoom before approving them.

Review Video and Audio

Any media required for participation should provide access to spoken and essential visual information.

  1. Play each video or audio file from the participant-facing link.
  2. Confirm that spoken audio has accurate captions.
  3. Correct names, specialized terms, and important errors in automatic captions.
  4. Provide a transcript when it supports equal access or review.
  5. Describe essential visual information that is not communicated through the audio.
  6. Check volume, playback controls, and whether captions can be turned on easily.

Tip: A video may display a caption button while still containing incomplete or inaccurate captions. Review the captions themselves.

Check the Final PDF

After exporting from Word or PowerPoint, review the PDF separately. The conversion process can alter links, tags, reading order, or document properties.

  1. Open the PDF and confirm that the text can be selected and searched.
  2. Verify that the file is tagged when a PDF accessibility tool is available.
  3. Confirm that the document title and primary language are set appropriately.
  4. Test links and bookmarks.
  5. Review reading order and table structure when possible.
  6. Confirm that images have alternative text or are marked appropriately.
  7. Run Adobe Acrobat Pro’s accessibility check or another approved PDF checker when available.
  8. Review every item marked Needs Manual Check.

Tip: If the PDF is image-only or lacks useful tags, return to the original source file rather than trying to repair the visual copy whenever possible.

Check the Sharing Experience

Accessibility includes whether participants can locate, open, download, and understand the material without unnecessary barriers.

  1. Use a concise, descriptive file name.
  2. Confirm that sharing permissions allow participants to open the file.
  3. Avoid requiring an unnecessary account or software purchase.
  4. Provide the accessible version at the same time as the material provided to everyone else.
  5. Identify the file type and purpose in the email, webpage, or course listing.
  6. Keep the accessible source file in case a participant needs another format.
  7. Test the link or attachment on another device or in a private browser window.

Tip: A file is not effectively available if participants encounter permission errors, confusing file names, expired links, or inaccessible third-party viewers.

Make a Final Decision

Assign a clear status rather than relying on a general impression that the file is probably ready.

  1. Ready to share: Automated and manual checks are complete, and no known barriers remain.
  2. Revise: The issue is understood and can be corrected in the source file.
  3. Get help: The file contains complex tables, scans, forms, media, or PDF issues that require additional expertise.
  4. Replace: The resource is inaccessible and an accessible alternative is more practical than remediation.

When in Doubt, Pause Before Sharing

Contact the UDOLLI office or the appropriate University accessibility resource when you cannot determine whether a file is usable. Delaying distribution briefly is preferable to knowingly creating a barrier for participants.

Common Questions

Does passing the Accessibility Checker mean the file is accessible?

No. The checker identifies many common problems but cannot evaluate every issue. Alternative-text quality, reading order, caption accuracy, usability, and participant understanding require manual review.

Which file should I correct when the PDF has a problem?

Correct the original Word document or PowerPoint presentation whenever possible, then export the PDF again. Source-file corrections are usually more reliable and easier to maintain.

What should I do with a scanned PDF?

Confirm that the text is selectable and searchable. An image-only scan requires text recognition and additional structure. When an accessible original or replacement is available, use that instead.

Do I need to check links and videos too?

Yes. Participants must be able to open linked resources, access captions or transcripts, and use any required external content without encountering an avoidable barrier.

What if I cannot correct a complex file?

Pause before sharing it and request assistance. Complex PDFs, scans, forms, tables, charts, and multimedia may require specialized tools or an accessible replacement.
