+The Blazor CheckBox component follows the WAI-ARIA Authoring Practices for checkboxes to ensure compatibility with assistive technologies. The following ARIA roles and attributes are used:
 
 | Attributes | Purpose |
 | --- | --- |
+| `role="checkbox"` | Identifies the element as a checkbox control to assistive technologies. |
+| `aria-checked` | Conveys the current state of the checkbox: `true`, `false`, or `mixed` (for indeterminate state). |
 | `aria-disabled` | Indicates that the element is perceivable but disabled, so it is not editable or otherwise operable. |
+| `aria-readonly` | Indicates that the value cannot be changed by the user (read-only state). |
+| `aria-labelledby` / `aria-label` | Provides an accessible name. When the `Label` parameter is used, it associates a visible label with the checkbox. |
+| `tabindex` | Ensures the checkbox is focusable via keyboard navigation in the expected order. |
+
+For guidance on ARIA usage, see the ARIA checkbox pattern (https://www.w3.org/WAI/ARIA/apg/patterns/checkbox/).
