You can track your unit’s progress using the Accessibility Dashboard in Siteimprove. Key indicators include improvements in your site’s “Progress towards site target,” and “Accessibility score”, a steady decrease in the number of accessibility issues, reductions in high-impact and high-risk problems, and positive trends shown in weekly reports and historical views.
