Twenty states strengthened their student proficiency standards from 2011 to 2013, while eight states weakened standards, according to a study in Education Next.
All the states showing strong improvements have adopted Common Core State Standards (CCSS), the authors note.
There remains a 30-point differential between the percentage of students defined as “proficient” by the average state and the percentage of students considered proficient by NAEP.
In many states, taxpayers have been funding tests that are a “weapon of mass deception,” writes Matthew Ladner. “Regardless of where you stand on the Common Core project, and we’ve beat the horse into hamburger on it here, state tests with the approximate rigor of a My Little Pony coloring book — look Mommy I colored this unicorn blue-I’m PROFICIENT!!! — deserve no one’s support.”
