Hi,

My understanding is that the WISC measures intelligence, which may or may not be correlated to academic knowledge. Achievement test results are more dependent on the child�s educational opportunities and independent initiative to learn, barring any LD issues. A group standardized test such as EXPLORE is often better understood and trusted by educators than independent achievement testing. Many HG and PG students, especially those in �average� educational settings, find enough ceiling on a test designed for older students, if only in one or two subtests.
