Ld refers to a heterogeneous group of disorders manifested by significant difficulties in the acquisition and use of listening, speaking, reading, writing, reasoning, or mathematical abilities. Ld are intrinsic to the individual and are presumed to be due to some sort of cns dysfunction. Ae and ge scores indicate the level of growth or development a child has reached. The tests are administered to large representative samples whose scores provide the standards or norms for aptitude or achievement (standards to which everyone else is subsequently compared). Pr indicates the percentage of the normative or standardization group that is below an individual"s percentile rank score. Ss indicates the number of standard units above or below the mean that an individual"s score is. It uses the sd of the distribution of scores around the mean to show how far an individual"s score differs from the mean.
