Among that provision’s most tenacious critics has been Robert Linn, a University of Colorado professor emeritus who is one of the nation’s foremost testing experts. He argued, almost from the law’s passage, that no society anywhere has brought 100 percent of students to proficiency, and that the annual gains required to meet the goal of universal proficiency were unrealistically rapid, since even great school systems rarely sustain annual increases in the proportion of students demonstrating proficiency topping three to four percentage points.

“If, no matter how hard teachers work, the school is labeled as a failure, that’s just demoralizing,” Dr. Linn said.

Only a freaking idiot with zero grasp of scientific principles would consider 100% in anything a realistic goal. 100% carbon-free cars! 100% withdrawal from foreign oil! 100% democracy in a fundamentalist Islamic country!

This list only needs universal healthcare and world peace to be complete.
