wj iii test of cognitive abilities bias
Description: This Woodcock Johnson III - Tests of Achievement (WJ III ACH) updates and expands the WJ-R Tests of Achievement (WJ-R ACH)) with the intension of improving the diagnostic power of the instrument. The WJ III ACH is designed to identify and describe an individualâs current strengths and weaknesses. Three oral tests, a diagnostic spelling test and a measure of phonological awareness have been added to evaluate fluency in reading and in math. The other WJ III battery, the WJ III Test of Cognitive Abilities (WJ III COG) is designed to measure general and specific cognitive functions. When these two batteries are administered together, they allow the tester to investigate over-underachievement and to examine patterns of intra-individual discrepancies among cognitive or achievement areas.
