New Mexico has been the lowest scoring state for academic achievement for eight years running. I had no idea when I started substitute teaching last year, but learned fast. In an algebra class for tenth graders, there were two kids ready for it out of twenty. I kept backing up to reach the LCD to start teaching from, and discovered that most of the class were not competent at addition and subtraction, let alone advanced topics like division and fractions. Yet they all get passed along with their peers.
This is the cohort that was supposed to learn this material during the covid years, but got a free pass. I think most of them will probably not catch up, and their career choices will be circumscribed by it. The overwrought covid safetyism with regard to children has untold numbers of lifelong victims.
