Two meanings of “accessible”
People use “accessible” in two related ways. In one sense it means reachable: a resource is accessible if it is free, online and not locked behind a fee or a login. In the other it means usable by people with different abilities: a resource is accessible if someone who is blind, deaf, dyslexic, has limited mobility or uses assistive tools can use it.
Open educational resources clearly help with the first meaning, because open licenses remove cost and permission barriers. Whether they help with the second depends on how each resource is made. The claim that open resources are a “game-changer” for accessible learning is partly true and partly overstated, and the difference is worth understanding.
What open licenses actually change
An open license gives people the right to reuse, adapt and redistribute. That has real consequences for accessibility:
- Someone can legally add captions to a video, or write a transcript, and share the improved version.
- A text can be converted into large print, a screen-reader-friendly layout or a simplified version.
- A resource can be translated, which matters for learners in a second language.
- Locked formats can be re-saved in flexible ones, if the license and the source files allow it.
With all-rights-reserved material, these changes may need permission from the owner, which often takes time and is sometimes refused. In that sense openness lowers the barrier to making alternative formats.
What open licenses do not change
A license does not make a resource accessible by itself. A free scanned textbook that is only an image of pages cannot be read by a screen reader. A freely licensed video with no captions is still unusable for a deaf learner. And the right to adapt is useless if nobody has the time, skill or funding to do the work. Many open resources are made by volunteers or small teams with limited accessibility knowledge, and quality varies widely. It would be misleading to assume that open means accessible.
Accessible by design
The most reliable approach is to build accessibility in from the start, which is far cheaper than repairing it later. The features that matter most are well established.
Structure. Use real headings in order, real lists and real tables with header cells. Screen readers and navigation tools depend on this structure, and it also makes pages easier for everyone to scan.
Images. Give meaningful alternative text to informative images, and mark decorative images so they are skipped. For complex charts, add a text summary or data table.
Audio and video. Provide accurate captions and a transcript. Captions help deaf and hard-of-hearing learners, and many other people use them, for example in noisy places or when learning in a second language. Audio description helps blind learners when important information is shown only visually.
Readable layout. Use sufficient color contrast, avoid conveying meaning by color alone, and allow text to be enlarged without breaking the page. Generous spacing and short lines are widely considered easier to read, and people with dyslexia sometimes find a plain layout and a clear typeface helpful, although individual preferences differ and no single setting suits everyone.
Plain language. Short sentences and defined terms help learners with reading difficulties and learners studying in a second language.
Flexible formats. Offer a web version, an editable document and, where possible, a version that works offline. A learner using assistive technology often needs a specific format, and a resource that exists in only one is a barrier. These are the kinds of accessible open formats that adapt to different devices and tools.
Keyboard and device independence. Interactive items should work without a mouse and on a phone.
The wider principle is universal design, meaning that features built for one group usually help many. The widely cited web accessibility standards describe testable requirements, and meeting them is a reasonable target. Your legal obligations depend on where you are, so consult official sources for those.
Weighing the big claim
Is open education a game-changer for accessible learning? A cautious answer has three parts.
First, open licensing removes cost and permission barriers, and that matters a great deal for learners who cannot afford materials. This is a real and well-understood benefit.
Second, open licensing makes it legally easier to produce accessible versions. This is a potential benefit, realized only when someone does the work.
Third, there is little reason to think openness improves accessibility by itself, and evidence on how accessible open resources are in practice is mixed. Be skeptical of any claim that gives precise figures without a clear source. Reports vary by collection and by what was measured.
A practical test for any resource
Before relying on a resource, try some quick checks:
- Can you tab through it with only a keyboard?
- Are there captions or a transcript for every recording?
- Does the text resize without losing content?
- Can you select and copy the text, or is it a picture of text?
- Is an editable version available?
- Does it say how to report an accessibility problem?
A resource that passes these is not guaranteed to suit every learner, but it is a better starting point. If you create resources, include a short accessibility note saying what you checked and what you did not, so the next person can build on your work.
