Maybe, but not all. In my state of Tennessee, the Gateway Exams for Algebra, English, History, and Science are required for graduation, and they're being revamped to be harder and more relevant.
A small percentage of my students failed the Algebra Gateway, but well over half scored "advanced" so I'm not sure what to think about the changes.
Students that fail these exams do not get a diploma, they get a "certificate of completion" or something like that... unless they manage to pass the exams on a retake.
Did you consider most of your students at least competent, and over half "advanced"?
