Quizplus · Accepted Answer

According to the Woodcock-Johnson manual, a score of 1.5 standard deviations below the mean is considered significant and may indicate a specific learning disability. Option A is incorrect because each domain has a different mean score, which differs by age group. Option B is too generalized and not entirely accurate. Option D is incorrect because while the domains are correlated, it is possible for someone to have a significantly lower score in one domain compared to the others.
