“With what should we replace standardized testing?” is not a good question. ST is akin to a disease in our schools; when your doctor removes a tumor, you do not expect to go home with diabetes as a replacement, you just go back to healthy living, or, in this case, educating. Or I can answer your question another way: replace ST with books. That, after all, is what we got rid of to make room for the tumor.
And no, the ST people are not well intended; they’re feeding at a big ol tax-funded trough.
