how can i explain accessibility to sighted people? our university website is accessible. however, there is a page to check status of a student. we call it ERP. Basically, the page is accessible. i can access site menu with a screen reader. However, I cannot access the corresponding menu. For example, I can click academic. Some options come after clicking academic. Sighted people can see and click them. However, I cannot navigate among those options and click with the screen reader.
