Accessibility statement
Moodle is designed to provide equal functionality and access to information for all users. This commitment means that there should be no barriers for people regardless of disabilities, assistive technologies used, different screen sizes, or various input devices (such as a mouse, keyboard, or touchscreen).
As part of our ongoing commitment to accessibility and continuously improving conformance with the WCAG 2.1 Level AA success criteria, Moodle is working with an external team of accessibility specialists to review the accessibility of its products through regular accessibility audits.
The accessibility conformance report is based on an audit of Moodle LMS by GrackleDocs (formerly AbleDocs), Moodle HQ’s external digital accessibility consultant, and internal testing and community audits. AbleDocs issued a Statement of Accessibility Conformance for WCAG 2.1 Level AA in January 2024.
We realise that accessibility is a continuous journey that requires constant focus and refinement. That’s why we commit our resources to ensuring our platform remains accessible to everyone.
Third-party integrations and accessibility disclaimer
Moodle is committed to ensuring accessibility across our platform, aligning with global accessibility standards such as WCAG 2.1 Level AA. However, Moodle allows for the integration of third-party tools, plugins, and Learning Tools Interoperability (LTI) applications, which are developed and maintained by external providers.
While we prioritise accessibility considerations when recommending or supporting integrations, it is the responsibility of the supplier of any third-party service or application to ensure that their offering is compliant. If accessibility compliance is a critical requirement for your institution or organisation, we recommend contacting the third-party provider directly to verify their conformance with relevant accessibility guidelines.

|
2.4.10 Section Headings Level AAA |
Supports | All pages have section headings, allowing users to orient themselves within the content structure. Moodle provides the tools to enable content creators to build user-generated content in an accessible way. |
2.4.11 Focus Not Obscured (Minimum) Level AA |

Partially supports | In some specific situations, the keyboard focus can be partially obscured. Known instances include:
|
2.4.13 Focus Appearance Level AAA |

2.5.1 Pointer Gestures Level A |
Supports | Moodle does not use any multi-point or path-based gestures within the UI. |
2.5.2 Pointer Cancellation Level A |

Supports | Pages in Moodle are rendered in the language based on the user’s preference. The language selector menu options have the lang attribute to convey the language for each menu option to assistive technologies. User-created content within Moodle can be tagged with the appropriate language of the content, and this can be done in parts. |

3.1.6 Pronunciation Level AAA |
Partially supports | The core Moodle system does not provide pronunciation support in most cases. However, Moodle does provide the facilities for user-created content to comply with this success criterion, including markup, automatic glossary linking, and the ability for a user to add additional content. |
3.2.1 On Focus Level A |

3.3.5 Help Level AAA |
Supports | Context-sensitive help is provided on every page for users to access. Additionally, instructions on complex forms and extensive tooltips for specific fields add additional help resources for users |
3.3.6 Error Prevention (All) Level AAA |
Partially supports | Form validation mechanisms allow users to correct their input when completing a form. Confirmation dialogues or pages are also present to prevent users from accidentally performing an irreversible action (e.g. data deletion, etc). However, there are some known instances where an irreversible action does not have a prior confirmation prompt, such as granting additional assignment attempts for students. |
3.3.7 Redundant Entry Level A |
Supports | Unless essential, data is pre-filled for users, or a sensible default is provided. |
