Hi
I am hoping one of you gurus can answer my questions. My DD6 was tested last spring on WJ ach. Her school wants to retest her. They are saying they want her retested because her scores were grade normed rather than age normed. It seems silly given she is young for the grade. I would think her percentiles would go up if her age was used not down. I thought the percentiles and SS were on age not grade. Does anyone know if the WJ- achievement percentiles or SS are age or grade normed? I am concerned the person testing has very little experience administering any kind of test. Does tester experience matter on achievement testing the way it can matter on IQ test? We have offered to bring her back to our outside tester and have the exact test they want administered to her. They don't seem to be interested in someone else testing her. It seems old given they accepted her IQ test from the same tester as valid.
Thanks for any input!
