Klasifikasi IQ dalam Penggunaan Pendidikan

IQ Classifications in Educational Use

*The terms High Average, Low Average and Extremely Low correspond to the terms Bright Normal, Dull Normal and Mental Defective, respectively, used in the 1955 WAIS manual.

**The term Extremely Low is used in place of the terms Mentally Retarded, used in the WAIS-R, and Intellectually Deficient, used in the WISC-III to avoid the implication that a very low IQ score is sufficient evidence by itself for the classification of “mental retardation” or “intellectually deficient.”

IQ Classifications in Psychiatric Use

Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV)
American Psychiatric Association, 1994

Istilah Educable Mental Retarded dan Trainable Mental Retarded yang digunakan dalam pendidikan khusus secara kasar setara dengan klasifikasi DSM untuk retardasi mental ringan dan sedang. Kriteria diagnostik DSM selanjutnya memerlukan penilaian dan penentuan gangguan fungsi adaptif untuk membuat diagnosis retardasi mental.

The terms Educable Mentally Retarded and Trainable Mentally Retarded used in special education are roughly equivalent to DSM classifications for mild and moderate mental retardation, respectively.  The DSM diagnostic criteria further require an assessment and determination of impairment in adaptive functioning in order to make a diagnosis of mental retardation.

(IQ Classifications No Longer in Use)

Mental deficiency used to be divided into the following sub-classifications, but these labels began to be abused by the public and are now largely obsolete: Borderline Deficiency (IQ 70-80), Moron (IQ 50-69), Imbecile (IQ 20-49) and Idiot (below 20). Mental deficiency is now generally called mental retardation.
