    I was skeptical of these numbers until I did the research. It’s even worse than I thought. Did you know that only 20% of students test in the top quintile? Is our children learning?

      One could construct tests where this isn’t a given. Create an exam with one really easy question and one really hard question. You’ll end up with a huge spike in the center and two tiny tails. The top quintile of correct answers (<=1.6 correct answers) will be vanishingly small.
