| 1.1.1 | A | Non-text ContentEvery image, icon, chart, or other non-text element must have a text alternative that serves the same purpose as the original. | ☐ Réussite ☐ Échec ☐ S.O. | |
| 1.2.1 | A | Audio-only and Video-only (Prerecorded)Prerecorded audio (e.g., a podcast clip) needs a transcript. Prerecorded video with no audio (e.g., a silent product demo) needs either a transcript or an audio track. | ☐ Réussite ☐ Échec ☐ S.O. | |
| 1.2.2 | A | Captions (Prerecorded)All prerecorded video that contains audio must have captions. Captions must be synchronised with the audio and include all speech and important non-speech sounds. | ☐ Réussite ☐ Échec ☐ S.O. | |
| 1.2.3 | A | Audio Description or Media Alternative (Prerecorded)Prerecorded video with audio track must have either an audio description (narration of visual information) or a full text alternative describing what is shown. | ☐ Réussite ☐ Échec ☐ S.O. | |
| 1.2.4 | AA | Captions (Live)Live video streams (webinars, live events, broadcasts) must have live captions provided in real time. | ☐ Réussite ☐ Échec ☐ S.O. | |
| 1.2.5 | AA | Audio Description (Prerecorded)At Level AA, audio description (not just a text alternative) is required for all prerecorded video. The full audio description track must be provided. | ☐ Réussite ☐ Échec ☐ S.O. | |
| 1.3.1 | A | Info and RelationshipsVisual structure (headings, lists, tables, form groupings) must be conveyed in the code, not just through styling. | ☐ Réussite ☐ Échec ☐ S.O. | |
| 1.3.2 | A | Meaningful SequenceWhen the order of content matters for understanding, the DOM order must reflect the correct reading sequence — not just the visual layout. | ☐ Réussite ☐ Échec ☐ S.O. | |
| 1.3.3 | A | Sensory CharacteristicsInstructions must not rely exclusively on visual cues like shape, color, or position. Include text-based references alongside sensory ones. | ☐ Réussite ☐ Échec ☐ S.O. | |
| 1.3.4 | AA | OrientationWebsites and apps must not lock to portrait or landscape. Users with mounted devices (e.g., wheelchair-mounted tablets) may be unable to rotate. | ☐ Réussite ☐ Échec ☐ S.O. | |
| 1.3.5 | AA | Identify Input PurposeForm fields collecting personal data must have autocomplete attributes so browsers and assistive technologies can autofill them. | ☐ Réussite ☐ Échec ☐ S.O. | |
| 1.4.1 | A | Use of ColorNever use color as the only way to communicate something. Always provide a secondary non-color cue. | ☐ Réussite ☐ Échec ☐ S.O. | |
| 1.4.2 | A | Audio ControlAudio that auto-plays for more than 3 seconds must be pausable or have independent volume control. | ☐ Réussite ☐ Échec ☐ S.O. | |

| 1.4.4 | AA | Resize TextUsers must be able to zoom to 200% without losing content or functionality. | ☐ Réussite ☐ Échec ☐ S.O. | |
| 1.4.5 | AA | Images of TextUse real HTML text instead of images of text wherever technically possible. Images of text cannot be resized, reflowed, or read by screen readers without alt text. | ☐ Réussite ☐ Échec ☐ S.O. | |
| 1.4.10 | AA | ReflowAt 320px viewport width (equivalent to 400% zoom on a 1280px screen), all content must be accessible without horizontal scrolling. | ☐ Réussite ☐ Échec ☐ S.O. | |
| 1.4.11 | AA | Non-text ContrastThe visual boundaries of form fields, buttons, checkboxes, and graphical elements used to understand content must have 3:1 contrast against adjacent colors. | ☐ Réussite ☐ Échec ☐ S.O. | |
| 1.4.12 | AA | Text SpacingWhen users override text spacing (line height 1.5×, paragraph spacing 2×, letter spacing 0.12em, word spacing 0.16em), no content should be lost or obscured. | ☐ Réussite ☐ Échec ☐ S.O. | |
| 1.4.13 | AA | Content on Hover or FocusTooltips and hover popups must be: hoverable (mouse can move over them), dismissible (Escape closes them), and persistent (they stay until explicitly closed). | ☐ Réussite ☐ Échec ☐ S.O. |

| 2.1.1 | A | KeyboardEverything a mouse user can do, a keyboard user must also be able to do. No functionality should require a mouse. | ☐ Réussite ☐ Échec ☐ S.O. | |
| 2.1.2 | A | No Keyboard TrapKeyboard users must never get stuck. Focus must always be escapable. Intentional focus traps in modals are acceptable only if Escape closes the modal. | ☐ Réussite ☐ Échec ☐ S.O. | |
| 2.1.4 | A | Character Key ShortcutsSingle-character keyboard shortcuts (like 'G' to go, 'F' for find) must be disableable or remappable. They conflict with speech input users who dictate text. | ☐ Réussite ☐ Échec ☐ S.O. | |
| 2.2.1 | A | Timing AdjustableSession timeouts, time-limited forms, and timed quizzes must give users a way to turn off, adjust, or extend the time limit. | ☐ Réussite ☐ Échec ☐ S.O. | |

| 2.3.1 | A | Three Flashes or Below ThresholdContent must not flash more than 3 times per second. Flashing content can cause seizures in people with photosensitive epilepsy. | ☐ Réussite ☐ Échec ☐ S.O. | |
| 2.4.1 | A | Bypass BlocksKeyboard users must be able to skip past repeated navigation blocks to reach the main content quickly. | ☐ Réussite ☐ Échec ☐ S.O. | |
| 2.4.2 | A | Page TitledEvery page must have a descriptive <title> element that helps users understand what the page is about. | ☐ Réussite ☐ Échec ☐ S.O. | |
| 2.4.3 | A | Focus OrderThe keyboard Tab order must follow a logical sequence — typically top-to-bottom, left-to-right in Western languages — that preserves meaning. | ☐ Réussite ☐ Échec ☐ S.O. | |
| 2.4.4 | A | Link Purpose (In Context)Link text must be descriptive enough to understand its destination — either from the text alone or from its surrounding context. | ☐ Réussite ☐ Échec ☐ S.O. | |
| 2.4.5 | AA | Multiple WaysUsers must have more than one way to find any page on the site (e.g., navigation + site search, or navigation + sitemap). | ☐ Réussite ☐ Échec ☐ S.O. | |
| 2.4.6 | AA | Headings and LabelsWhen headings and form labels are used, they must be descriptive — they need not be comprehensive, but they must accurately describe their associated content. | ☐ Réussite ☐ Échec ☐ S.O. | |
| 2.4.7 | AA | Focus VisibleKeyboard users must always be able to see which element has focus. Never suppress the focus outline completely. | ☐ Réussite ☐ Échec ☐ S.O. | |

| 2.5.2 | A | Pointer CancellationDon't trigger actions on mousedown/touchstart if the user might accidentally tap. Use mouseup/click (which fires on up-event) so users can cancel by moving away. | ☐ Réussite ☐ Échec ☐ S.O. | |
| 2.5.3 | A | Label in NameThe accessible name of a button or link must contain the visible text label — this is essential for voice control users who say what they see. | ☐ Réussite ☐ Échec ☐ S.O. | |
| 2.5.4 | A | Motion ActuationFeatures that use device shake, tilt, or motion must also be operable via standard UI controls, and motion must be disableable. | ☐ Réussite ☐ Échec ☐ S.O. | |
| 2.5.7 | AA | Dragging MovementsNew in WCAG 2.2: drag-and-drop must have a click/tap alternative. Sliders must be adjustable without dragging. | ☐ Réussite ☐ Échec ☐ S.O. | |

| 3.2.1 | A | On FocusReceiving focus must never automatically navigate, submit a form, or launch a popup. Focus changes must be predictable. | ☐ Réussite ☐ Échec ☐ S.O. | |
| 3.2.2 | A | On InputChanging a form control (selecting a dropdown option, checking a box) must not automatically navigate or submit without warning. | ☐ Réussite ☐ Échec ☐ S.O. | |
| 3.2.3 | AA | Consistent NavigationNavigation menus must appear in the same order on every page. Users with cognitive disabilities rely on consistent placement. | ☐ Réussite ☐ Échec ☐ S.O. | |
| 3.2.4 | AA | Consistent IdentificationThe same function must have the same label everywhere on the site. A search button should not be labelled 'Search' on one page and 'Find' on another. | ☐ Réussite ☐ Échec ☐ S.O. | |

| 3.3.3 | AA | Error SuggestionError messages must tell users how to fix the error — not just that an error occurred. Exceptions apply for security-sensitive validations. | ☐ Réussite ☐ Échec ☐ S.O. | |
| 3.3.4 | AA | Error Prevention (Legal, Financial, Data)High-stakes forms (purchases, legal agreements, exam submissions, data deletion) must let users review, correct, or reverse the action. | ☐ Réussite ☐ Échec ☐ S.O. | |
| 3.3.7 | A | Redundant EntryNew in WCAG 2.2: if users must re-enter data they already provided in the same session, auto-populate it or let them select it from a list. | ☐ Réussite ☐ Échec ☐ S.O. | |
| 3.3.8 | AA | Accessible Authentication (Minimum)New in WCAG 2.2: authentication must not require a cognitive-only challenge unless an alternative exists. Password managers and magic links must be supported. | ☐ Réussite ☐ Échec ☐ S.O. | |
| 3.3.9 | AAA | Accessible Authentication (Improved)New in WCAG 2.2 (AAA): No authentication step may require a cognitive function test of any kind.

| 4.1.1 | A | ParsingSC 4.1.1 is obsolete in WCAG 2.2 and always passes with modern browsers. It was removed because modern browsers handle malformed HTML gracefully and assistive technologies do not rely on valid HTML parsing. | ☐ Réussite ☐ Échec ☐ S.O. | |
| 4.1.2 | A | Name, Role, ValueEvery interactive element must expose its name (what it is called), role (what type of control it is), and current state/value to assistive technologies. | ☐ Réussite ☐ Échec ☐ S.O. | |
| 4.1.3 | AA | Status MessagesSuccess messages, loading states, result counts, and errors must be announced by screen readers without moving focus to them. | ☐ Réussite ☐ Échec ☐ S.O. |
