Okay...I'm confused! "Even most high performing 10th graders recieve a technically accurate measure of their skill", when they preceed that statement by saying the ceiling is only at about the 93rd percentile?
I know it's early, but does that make sense?
I'd read it this way: "most" means more than 50%, so if "high performing" means, say, above the 75th percentile, then of the high performing 10th graders, the fraction who receive a technically accurate measure, i.e. do not hit the ceiling, is (93-75)/(100-75), which is greater than 50%, i.e., most! It all rests on what the definition of "high performing" is...
