One of the problems with SATs is that there are some very pushy parents out there who push their offspring, even paying for extra tuition if they feel it is needed. They put pressure on teachers and complain vigorously if they think their child is not being given enough practice SATs papers. Caught between them and the targets they need to meet teachers have no choice but to teach to SATs, this means they introduce things which they know will up the children's marks. One of these techniques is "Wow words" giving a list of words which can bring extra marks if a child can fit some in to the writing test. The child doesn't have any real understanding of the vocabulary they are using, they use them in the SATs and then forget about them.
