Tennessee has had years of problems with test vendors. This year, then state thought all the glitches were fixed. Wrong. Thousands of scores were wrong.

About 9,400 students across the state received incorrect scores after the testing vendor, Questar, used a scanning program that included an error.

Our friend and reader Duane Swacker would say that all the scores are meaningless and measure nothing. I just finished reading Daniel Koretz’s new book, “The Testing Charade: Pretending to Improve Education,” and he might agree with Duane. The chances are that the scores have been corrupted by test prep and score inflation. Throw them all out.
