Accessibility Guidelines

In an asynchronous class, students experience much of the course through your announcements, videos, and supplemental materials. Course content is provided and maintained by CVA, but any materials you create and share are your responsibility.

Big Idea: Accessibility is not an extra step. It is a requirement for anything you create or share with students.

Know Your Scope

What's Your Responsibility vs. CVA's?

CVA builds and maintains all core course content. Your accessibility responsibility applies to the supplemental layer: the materials you personally create, record, or post alongside the course.

Your Responsibility

  • Class Announcements you write
  • Digital graphics and one-pagers you create
  • Videos and screen recordings you record
  • Images you insert into announcements

CVA's Responsibility

  • Course pages and modules
  • Assignments and rubrics built into the course
  • Embedded videos provided in the course shell
  • Discussion boards and quiz structures
  • Publisher or third-party content included in course design
Accessibility Basics

Guidelines to Follow

Select the tool you are using to see specific accessibility requirements and subcategories. Reach out to CVA Teacher Support if you need any additional help or guidance in leveraging accessibility basics for all learners.

Canva Graphics & Announcements
Graphics • Visual Announcements • Infographics

Announcements are one of the primary ways students receive information from you inside the Digital Classroom. Canva is useful for creating polished visuals, but a graphic alone is not enough when it contains important course information. Students using screen readers, translation tools, small screens, or low-bandwidth connections may not be able to access information that only lives inside an image.

Text

Accessible text helps all students access important information, whether they are reading it, listening to it, translating it, or using assistive technology.

  • Break long announcements into short paragraphs or sections.
  • Avoid large blocks of unbroken text.
  • Use bold to highlight key information, not color alone.
Color, Contrast, and Readability

Design choices affect whether students can read the content at all.

  • Use high contrast between text and background (dark text on light background or vice versa).
  • Avoid decorative or script fonts for any important information.
  • Avoid tiny text, dense layouts, or overcrowded designs.
  • Do not use color alone to convey meaning. Always pair it with text or a label.
Text and Information Inside Graphics

If your Canva design contains any important course information, that information must also appear as readable text outside the graphic.

  • Do not rely on the image as the only source of dates, links, directions, or reminders.
  • Repeat all key information in the announcement or page body as regular text.
  • Make sure links appear as clickable text, not only inside the graphic.
Alt Text for Images

Add alt text to every image that contains or supports important information. When you insert a Canva design or any image into Canvas, add alt text that describes the content and purpose of the image.

  • Strong: "Weekly announcement graphic showing Unit 3 due Friday, October 18, and a live help session Tuesday at 4:00 PM."
  • Weak: "Image" or "Announcement."
  • If the image is purely decorative and adds no information, mark the image as Decorative.
Links and Buttons
  • Always hyperlink descriptive text: "Join Tuesday's help session" — not "click here."
  • Test every link before publishing.
  • Do not embed the only copy of a link inside a Canva image — repeat it as clickable text in the announcement body.
Images in Announcements
  • Add alt text to every image that contains or supports important information.
  • If a graphic is included, repeat all key content (dates, links, instructions) as plain text below or above it.
  • Decorative images that add no information should have blank alt text.
Mobile and Email Readability

Many students read announcements on their phone or through email notifications.

  • Keep formatting simple — complex layouts often break in email view.
  • Avoid relying on tables or multi-column layouts for announcements.
  • Place the most important information near the top of the announcement.
  • Test the announcement on a mobile device if you are using complex formatting.
Videos & Screen Recordings
Teams and Zoom Recordings • Panopto • Welcome Videos • Tutorials

Teacher-created videos must be accessible to students who cannot hear the audio, students who process information better through text, and students who need to review content later or in a different language.

Captions

Captions are required for any video that includes instructional content.

  • Auto-generated captions are often inaccurate — review and correct them before posting.
  • Captions should include speaker identification when more than one person is speaking.
  • Avoid using captions only as a courtesy — they are a requirement.
Transcripts

Provide a written transcript whenever a video includes directions, explanations, or instructional content students need to act on.

  • A transcript allows students to search, translate, or reference the content without replaying the video.
  • Copy the corrected caption file and paste it as text in the page or announcement, or attach it as a document.
Recording Practices

How you record affects how accessible the video is for all students.

  • Use clear audio and minimize background noise.
  • Describe important visual elements out loud — do not rely on students being able to see your screen.
  • Avoid vague references like "click here" or "look over there" — name what students should select or notice.
  • Keep videos focused and organized so students can easily find what they need on a second viewing.
Quick Check

Before You Post, Ask Yourself These Six Questions

Run through this list before posting any announcement, video, graphic, or document. If you answer no to any of these, revise before sharing. If you or a student encounter an accessibility issue, contact CVA Teacher Support.

Can students access the same information without relying only on an image?
If important info is only inside a graphic, repeat it as regular text.

Did I include alt text for meaningful images?
Describe what the image shows and why it matters — not just "image" or "screenshot."

Do my videos include accurate captions and a transcript when needed?
Auto-captions alone are often inaccurate. Review and correct them before posting.

Is the text readable? High contrast, large enough, and easy to scan?
Decorative fonts and low-contrast color combinations create barriers for many students.

Are links and buttons clearly labeled?
Use "Open the Week 3 Assignment" — not "click here."

Would this resource still make sense if a student couldn't see the visual design?
Screen readers, translation tools, and low-bandwidth devices may strip visuals entirely.
