In my last post, I argued that the SAT essay might be inappropriately difficult for its intended purposes and that floor effects make it essentially worthless for distinguishing among lower-ability students. In this post, I'm going to argue that the SAT essay score appears similarly unhelpful for distinguishing among high-ability students.

A Real Grammar Quiz (version 2)

Submitted by Karl Hagen
Several years ago, I created something I called a "Real Grammar Quiz." It was born of my irritation with the many so-called grammar quizzes available on the Internet which treat "grammar" as a catch-all term for "writing usage" and focus mostly on spelling, punctuation, and diction rather than grammar in the strict sense. This quiz has proven to be continuously popular since I released it. I've even received reports of a company using it to help screen job applicants for their knowledge of formal grammar.

So for those who are drawn to such things, I've created a second version of the quiz. This is a parallel form to the earlier quiz, with all new questions but constructed with approximately the same balance of question types and (I hope) difficulty.

Unfortunately, this mock test had so many flaws and outright errors, was so unrepresentative of the actual Literature Test, that it's hard to see how it could diagnose much of anything. Just how terrible was it? Here's just one example:
