A learning resource can be accurate, attractive and impossible for some students to use.
The barrier is often not dramatic. It may be a scanned PDF that cannot be read aloud, a video without captions, a chart whose meaning depends on colour, or a page with headings that only look like headings. Each problem is small at the point of creation and expensive when a student encounters it during a lesson.
Accessibility is therefore best treated as part of preparing the material, not as a repair requested after access has already failed.
Australian educators and education providers have obligations under the Disability Discrimination Act 1992 and the Disability Standards for Education 2005, including making reasonable adjustments so students with disability can participate and learn on the same basis as other students. The Australian Government provides educator resources explaining those responsibilities.
The following check is not a full accessibility audit. It is a practical first pass that teachers can apply before uploading a document, slide deck, video or LMS page.
1. Can the structure be understood without the formatting?
Use built-in heading styles rather than making a line bold and larger. A clear heading structure helps every reader scan the material and allows screen-reader users to navigate by section.
Check that there is one descriptive title, that heading levels follow a logical order, and that lists are created with the list tool rather than typed with dashes or spaces.
2. Do images have a useful text alternative?
If an image carries information, add alternative text that communicates its purpose in that context. “Graph” is rarely enough. “Bar chart showing attendance rising from Term 1 to Term 4” tells the reader what matters.
If an image is purely decorative, mark it as decorative or give it an empty text alternative so it does not create unnecessary noise.
The W3C Web Accessibility Initiative guidance on alternative text includes a decision process for different kinds of images.
3. Are links meaningful on their own?
A page filled with “click here” links is difficult to scan and confusing when links are read as a separate list. Use text that describes the destination or action, such as “Download the Year 9 fieldwork template”.
Avoid pasting a long web address into the middle of a sentence. Link the relevant words and, when necessary, state that the destination is a PDF, video or external site.
4. Is essential meaning carried by colour alone?
Colour can support understanding, but it should not be the only signal. If correct answers are green and incorrect answers are red, add labels, symbols or another cue. In a chart, use direct labels or patterns as well as colour.
Also check contrast. Pale text on a white background and text placed over a busy photograph can be difficult to read in an ordinary classroom, particularly on a projector or small screen.
5. Can a student use the material without a mouse?
For an LMS page or interactive resource, try moving through it using the Tab key. The focus should move in a sensible order, and the currently selected item should be visible. Buttons, links, menus and form fields should all be reachable.
This quick test will not find every keyboard-access issue, but it often exposes a major barrier within minutes.
6. Do audio and video have alternatives?
Provide accurate captions for video and a transcript where students need the spoken content in another form. Automatically generated captions are a starting point, not a finished product: names, technical terms and punctuation need checking.
If important information appears only visually—such as a process demonstrated without narration—include a description in the surrounding text or audio.
7. Is the file itself usable?
A PDF may look fine and still be an image of text. Try selecting a sentence. If the words cannot be selected, searched or read aloud, locate the source document and export an accessible version rather than relying on the scan.
For Word documents and slide decks, use the application’s accessibility checker, but do not treat a green result as proof. Automated tools can identify missing information; they cannot always judge whether a heading is meaningful or alternative text is useful.
A five-minute student test
Before publishing the material, ask:
- Can I identify its purpose from the title?
- Can I follow the structure quickly?
- Can I understand every image, link and instruction without guessing?
- Can I access the same learning through more than one mode where that is needed?
- Have I tested the actual file or page students will receive?
The W3C’s Easy Checks resource makes an important distinction: a quick review can find basic barriers, but passing it does not demonstrate full conformance with the Web Content Accessibility Guidelines.
Build accessibility into the template
The most sustainable improvement is not asking every teacher to remember a long technical standard. It is giving staff accessible templates, agreed captioning and document processes, and a clear place to seek help.
Start with one frequently used resource. Fix its headings, links, images, colour cues and media alternatives, then save it as the new starting point. Accessibility becomes easier when the correct practice is already built into the material teachers reuse.
