Accessibility Progress Formula

A formula for quantitatively tracking progress in addressing accessibility issues on a website, expressed as APPF = A / ((A + B) + (T - C)), where A is the number of applicable checklist items that have been addressed, B is the number not yet addressed, T is the total number of checklist items, and C is the number found not applicable. The formula produces a percentage that indicates how much of the applicable accessibility work has been completed. It provides a concrete metric that accessibility specialists can use to communicate progress to management and development teams, helping to make accessibility improvement visible and measurable rather than an open-ended task.
