Admins can choose from a range of scoring models to apply across their Panorama instance, based on their institution's unique accessibility requirements. These scoring models determine document accessibility scores based on a defined set of criteria. The sections below describe each model and how its accessibility scores are calculated.
Dynamic Severity Model
Accessibility scores are calculated based on the range of the highest severity level. Severity levels are defined as Minor, Major, and Severe.
Listed below are the ranges for each severity level.
- Minor: 70% - 100%
- Major: 30% - 70%
- Severe: 0% - 30%
For example, if a document has 15 Minor issues and 1 Major issue, the document will receive an accessibility score from the range of the Major issue.
Static Severity Model
Accessibility scores are calculated based on a fixed score for the highest severity level detected.
Listed below are the accessibility scores that will be assigned based on the highest severity level detected.
- Minor: 70%
- Major: 30%
- Severe: 0%
For example, if a document has 10 Minor issues, 5 Major issues, and 1 Severe issue, the document will receive an accessibility score of 0%.
Detraction Model
Accessibility scores are calculated based on the number of failed accessibility checks. Failed accessibility checks are worth twice as much as passed checks. This model ensures that creators prioritize resolving failed accessibility checks to increase the accessibility scores of documents.
Element Model
Accessibility scores are calculated based on the percentage of elements that did not pass the accessibility checks. It is calculated by dividing the elements that did not pass the accessibility checks by the document’s total number of elements. The accessibility issues within each element do not affect the score.
Elements are defined as:
- Paragraphs
- Tables
- Headers
- Lists
- HTML Links
- Images
- Videos
- Pages/slides
- The entire document
Weight Model
Accessibility scores are calculated based on evaluating all failed checks according to their assigned weights and measuring them against the document’s total checks.
Each severity level—Minor, Major, and Severe—has a different assigned custom weight to influence how they affects a document's overall accessibility score. Learn more about Customizing Severity Weighting Settings for Panorama.
Strict Detraction Model
Accessibility scores are calculated based on assigning documents a starting score of 100 and deducting points according to the weight of each issue.
Each severity level—Minor, Major, and Severe—has a different assigned custom weight to influence how they affects a document's overall accessibility score. Learn more about Customizing Severity Weighting Settings for Panorama.
