I just received some test results and need some help! My DS took the WPSSI at 3 and a half to get into a gifted program and scored with a full score IQ of 140 which was 99.7% I can't recall the subtests but I remember he was in the 99.9% on the Verbal and a little less on the other part. He was just given a one word expressive vocabulary test for a different public school and I called to get the results and she told me he scored 111 which is at the 75%. I understand the one word expressive vocabulary test was only 10 minutes long but I am concerned with that score. Does this test correlate with a verbal IQ score and if so can IQ go down and by that much?
