A Florida school board member (identity revealed here) took his state's 10th grade standardized tests in math and reading. He reported not knowing how to do any of the math problems, and only got 10 out of 60 questions right after guessing.
This man was an educator for years and has multiple advanced degrees, and he couldn't get a question right on an exam that probably doesn't go past 8th grade algebra? (The WaPo article includes links to similar questions, and I could answer those problems correctly, in my head.)
I would be more than happy to see school board members, teachers, and administrators take these exams, but only if they're compared to volunteers of similar ages from the community. That would help determine if the problem is with the exam, or if it's between the exam and the chair.
