The tester who tested my ds said that WISC-IV was the better test for getting into DYS along with the WIAT-II. So, those ar the test that we went with since she is the expert. However, after reading Sittin Pretty's post I am wondering if he should have taken the SB5? He is 7 (2nd grader) and doing 5th grade math with Abeka (if it where Saxon he would probably be doing 7/8).
