TFA said:Ten states now use test scores as the main criterion in teacher evaluations. Other states reward high-scoring teachers with up to $25,000 bonuses while low scores could result in principals losing their jobs or entire schools closing. Even as the number of scandals grows, experts say it remains fairly easy for teachers and principals to get away with ethical lapses.
And this is the issue, along with cutting funding/closing failing schools instead of attempting to correct the course. There's this high pressure to do well to get a pay raise and more funding otherwise you lose your job. So stupid.
NCLB probably screwed more things up for standardized tests in general than standardized tests did themselves.
