As Hess put it (in 2004), “Washington ought to establish clear and uniform expectations regarding student mastery in reading and math at the fourth-, eighth- and perhaps twelfth-grade level.”
No reformer in 2015 considers this to be an acceptable position. Not (just) because of the "Washington ought to establish" part, but even more because Hess only calls for standards at grades 4, 8 and 12. The easiest way to improve the Common Core standards would be to delete the standards in grades K, 1, 2, 3, 5, 6, 7, 9-10 and 11-12. Keep grade 4, 8 and "college and career readiness."
Seriously, that would be way better.
Unfortunately, Old Rick also thought this:
The performance of schools and districts should be judged primarily on how much students are learning while in school—not on the absolute level of student achievement.
Which leads to wanting multiple versions of standards at every grade level.
