thought I would investigate the flip side.
Standardized
testing may well be flawed, but among the alternatives
it may be the least objectionable.
Scratching the surface yielded this...

"When 300 papers were graded by fifty-three graders (a
total of 15,900 readings), more than one third of the
papers received every possible grade. That is, 101 of
the 300 papers received all nine grades: A, A-, B+, B,
B-, C+, C, C-, and D. ????
94 percent [of the papers] received either seven,
eight, or nine different grades; and no essay received
less than five different grades from fifty-three
readers."
100% of the 300 essays received 5 different grades!
1961 study by Paul Diederich and his colleagues, as
reported by E. D, Hirsch in "The Schools We Need and
Why We Don't Have Them"
