The Lose-Lose of Value-Added (EVAAS) in Houston
Terry Grier brought with him to Houston a fixation for test scores that he learned in Guilford, NC, where he came under the spell of former adjunct professor and agricultural statistician, Bill Sanders, who created there a vast subsidiary for SAS, Inc. in school testing--the value-added variety. The Sanders brand, EVAAS, has become so big, in fact, that Sanders has moved from the SAS campus back to Ground Zero in TN, where he got his start and where there are now a half-billion reasons, thanks to RttT, to get EVAAS sewn into the fabric of Test Scores Gone Wild--the Tennessee Version.
He did the same for his TVAAS brand in the 1980s, when he managed to get his proprietary statistical wizardry added to the Tennessee Code Annotated as THE algorithm to be used for testing kids. No doubt he is fantasizing about getting it into federal law at this point.
Now it is teachers who are to be evaluated based on the Sanders scheme, and Sanders couldn't care less about
