Severity classification of rules
The rules in BrowserStack Accessibility Testing are classified according to the following different severity levels:
- Critical
- Serious
- Moderate
- Minor
These severity levels indicate the intensity of the accessibility issues experienced by users when the particular rule is violated.
Explanation of severity levels
The different severity levels are explained below:
| Severity Level | Impact on Users | Compliance Risk | User Experience | Remediation Priority |
|---|---|---|---|---|
| Critical | Blocks content or functionality, preventing access to fundamental features or content. | High risk of non-compliance. | Users with disabilities cannot perform essential tasks or access critical information. | Top priority |
| Serious | Creates significant barriers, partially preventing access to fundamental features or content. | Moderate to high risk of non-compliance. | Users relying on assistive technologies experience significant frustration. | High priority |
| Moderate | Introduces some barriers but does not prevent access to fundamental features or content. | Low to moderate risk of non-compliance. | Users may encounter obstacles but can still achieve their goals with some difficulty. | Medium priority |
| Minor | Causes minor inconveniences or annoyances but does not significantly hinder access. | Low risk of non-compliance. | Users may notice minor issues, but these do not substantially affect their experience. | Low priority |
To ensure compliance and for maximizing accessibility of your websites, we recommend to fix issues of all severity levels.
