In the United States and Canada, the term<unk>  (LD) refers to a group of disorders that affect a broad range of academic and functional skills including the ability to speak, listen, read, write, spell, reason and organize information.  A<unk>  is not indicative of low intelligence.  People with<unk> es sometimes have difficulty achieving at his or her intellectual level because of a deficit in one or more of the ways the brain processes information.  The National Joint Committee for<unk> es (NJCLD) defines the term<unk>  as "... a heterogeneous group of disorders manifested by significant difficulties in the acquisition and use of listening, speaking, reading, writing, reasoning or mathematical abilities. These disorders are intrinsic to the individual and presumed to be due to Central Nervous System Dysfunction. Even though a<unk>  may occur concomitantly with other handicapping conditions (e.g. sensory impairment, mental retardation, social and emotional disturbance) or environmental influences (e.g. cultural differences, insufficient/inappropriate instruction, psychogenic factors) it is not the direct result of those conditions or influences."  The term referred to a discrepancy between a child’s apparent capacity to learn and his or her level of achievement.
