Accessibility best practices checklist

Run this checklist once per course before you publish. It takes about 15 minutes and catches the vast majority of accessibility regressions.

Pre-publish accessibility checklist

Text content

• All headings use H2–H4 (not bold-as-heading).
• Every paragraph fits the reading-age target (Hemingway grade ≤ 10).
• No “click here” links — every link describes its destination.
• Acronyms expanded on first use (GDC → General Dental Council).

Images

• Every image has alt text.
• Decorative images use alt="".
• Clinical images include a short description in the body text, not just the alt.
• Image-only diagrams have a text equivalent in the unit.

Video

• Every video has a transcript or accurate captions.
• Auto-captions have been reviewed (not raw YouTube output).
• No essential information conveyed only in the audio.

Problems and XBlocks

• Every problem can be answered with keyboard only.
• Image-based problems have a text-based alternative or clear alt text.
• No time limits, or time limits are extendable on request.

Colour and contrast

• No information conveyed by colour alone.
• No inline colour overrides on text (let the theme handle it).

Course-wide

• Course-about page describes the course in plain English.
• Course overview lists CPD hours and GDC outcomes addressed.
• Support email is visible: support@learning.endo360.co.uk.
