Educable Mentally Retarded (EMR)
"Educable mentally retarded" is an obsolete term used to refer to individuals who have a mental development of between 8 and 12 years and that can be educated to around the 6th grade level.
This generally translates as having an IQ score less than 70 (2-3 standard deviations below normal). Children that are given this classification after school entrance have generally had a fairly normal social and physical development and their intellectual deficits don't become noticeable until they start having problems with academic subjects. At this level of intellectual handicap, those with this condition can be taught to live with some level of independence and hold down some type of employment.
