Dear lord. If Kaye really asked this question in this way, she is a fool beyond belief.
The highest level a student can be placed into on the NAEP is "Advanced Proficient." The cut score for this level - in other words, the lowest possible score you need to get to be "Advanced Proficient" - for 4th Grade math is 268. Only 7% of 4th Graders achieved this score in 2011.
If what Kaye asserts is true (assuming she asserted it at all), then even our very top scorers would barely be above failing; our very best testing kids are really low-performing.
Does that sound right to you?
I'm going to hold off saying any more until I see the show myself.
