How to Set Up PowerPoint Accessibility Standards and Deck Governance for a Team

Fixing accessibility one deck at a time doesn't scale. If forty writers each learn about alt text from a checker warning the night before a deadline, you'll get forty different standards and a lot of "image1.png" descriptions. The fix is to move accessibility upstream: into the template, into written standards and into a review step that runs the same way every time.

This page is for the person who sets the rules. You'll turn accessibility requirements into template defaults, write alt text standards your team can apply consistently, draft a short governance policy, and set up a review workflow with a remediation log. The running example is the tutoring site's course team, which publishes lesson decks and PDF handouts to learners who use screen readers, keyboard navigation and captions.

Treat accessibility as design quality

An accessible slide is usually a better slide for everyone. A real title helps a screen reader user navigate, and it helps a sighted learner scanning the PDF. Good contrast helps low-vision learners and anyone watching on a projector in a bright room.

Seven qualities cover most of what goes wrong in decks:

Build accessible defaults into the template

The cheapest accessibility fix is the one nobody has to make. A well-built template prevents most problems before a writer types anything.

Built-in layouts with real placeholders. Writers who use layouts get real titles and logical reading order for free. Writers who use Blank and draw text boxes get neither. Make sure every layout in your library has a title placeholder, including image and quote layouts. If a design calls for no visible title, keep the title placeholder and position it just off the slide, so it still exists for screen readers and the slide still has a title in the outline.

Placeholder order. On each layout, the order you insert placeholders sets their default reading order. Add the title first, then content top to bottom, left to right (or in whatever order makes sense to read). Check it after building: open Review› then Check Accessibility› then Reading Order Pane on a sample slide.

Safe colors. Define theme colors in pairs that pass contrast. The widely used WCAG 2 AA thresholds are 4.5:1 for normal text and 3:1 for large text (about 18 pt, or 14 pt bold). Test every text-on-background combination your template allows, and say in the style guide which accent colors are for shapes only.

Font sizes. Set master text sizes so the smallest body level is still readable when projected and in a PDF. Many teams set 18 pt as the minimum body size and avoid going below about 12 pt even for source lines.

Focus order for interactive slides. On slides with action buttons or hyperlinks, keyboard users tab through objects in reading order. Put navigation buttons in a predictable position in the reading order (for example, after the content and before decorative items) on every interactive layout.

Write alt text standards your team can apply

"Add alt text" isn't a standard. Forty writers will produce forty styles. Give them a short rule per object type and an example of each.

First, the decision every writer makes: is this object meaningful or decorative? If removing it would lose information, it's meaningful and needs alt text. If it's a background flourish, divider line or mood photo that adds nothing to the point, mark it decorative. In PowerPoint for Windows, right-click the object, choose View Alt Text, and check Mark as decorative.

Microsoft's guidance is to keep alt text to a short sentence or two, and not to repeat text that's already on the slide. For complex graphics where a sentence or two isn't enough, put the full description in the speaker notes, the PDF handout or a following slide, and point to it from the alt text.

Write a one-page governance policy

Governance means the rules a team must follow, written down, with an owner. Keep the policy to one page so it actually gets read. Use must for requirements that block publishing and should for strong recommendations.

Two habits keep governance useful rather than bureaucratic:

• Every rule has a reason the team can repeat. "Tagged PDF, because screen readers need structure" sticks. "Because policy" doesn't.
• Every rule is checkable. If a reviewer can't tell whether a deck passes, rewrite the rule.

Run a repeatable accessibility review

The checker is a starting point, not the finish line. It catches missing alt text, missing titles, some contrast problems and objects it thinks are out of order. It can't judge whether alt text is useful, whether reading order makes sense, or whether a video's captions are accurate. Microsoft also notes that the checker can miss contrast problems in some cases, such as transparent text boxes over the background. Run the same five steps on every deck:

1. Automated check. Review› then Check Accessibility. Fix every error and review every warning. Keep the pane open while you fix things; it updates as you go.
2. Manual reading order check. Open Review› then Check Accessibility› then Reading Order Pane and go through each slide. Does the order match how you'd read the slide aloud? Use the arrows in the pane to reorder.
3. Alt text quality check. Read each alt text without looking at the image. Could you understand the slide's point? Does it follow your standard?
4. Media caption check. Play each video with sound off. Are captions present, accurate and in sync? In PowerPoint for Windows, you can add a caption file to an inserted video with Playback › Caption Options › Insert Captions (WebVTT format).
5. PDF export check. Export with File› then Export› then Create PDF/XPS Document, click Options, and make sure Document structure tags for accessibility is checked. Open the PDF and confirm text is selectable, the reading order holds and links work.

Then record what you found in a remediation log:

The log does more than prove compliance. Review it each term: if the same issue keeps appearing, the fix belongs in the template, the standard or training, not in more reviewing.

Scale it across a team

Once the template, standards, policy and workflow exist, scaling is mostly about feedback loops:

• Automate the finding. A macro or script that lists missing titles and missing alt text across every deck (see the automation tutorial) turns a manual hunt into a report. People still write the fixes.
• Spot-audit published decks. Each term, pick a sample of published decks and run the full five-step review. Compare results with earlier terms.
• Train with real failures. Turn the most common remediation log entries into a short "fix this broken slide" exercise for new writers.
• Close the loop with the template. Each recurring issue becomes a template change, a clearer placeholder prompt or a new example in the sample deck.

Common mistakes with accessibility at scale

• Treating the checker as a pass/fail certificate. A clean checker result can still mean bad reading order and useless alt text.
• Leaving accessibility to the last day. Fixes at the end are rushed and often break layouts.
• Alt text that describes pixels, not purpose. "Blue bars on a white background" tells the listener nothing about the point.
• Deleting titles for design reasons. Keep the placeholder and move it off the slide instead.
• Rules nobody can check. "Make it accessible" isn't a rule. "Checker clean, captions on every video, chart alt text states the finding" is.
• No owner. A policy without an owner and a review date goes stale within a term.
• Fixing the same issue in every deck. If it shows up repeatedly in the remediation log, fix the template.
