I wish it were dubious. I recently worked with 11th grade Algebra 2 students in New Mexico and found exactly that, and worse. Most couldn't begin to do algebra because they couldn't do simple addition and subtraction. Out of a class of 24 there were two who were arguably ready for it. But everyone is moved forward anyway. I understand your skepticism because I was shocked by it. The teachers said it all went down the drain during Covid and has not recovered.

It must severely limit what they can learn in college.
