9. Mental retardation 
ICD-10 specifies 4 degrees of mental retardation but advises that the IQ levels for grading severity of 
mental retardation be only for guidance and should not be applied rigidly in view of the problems of 
cross-cultural validity. Instead, the severity must be graded primarily by functioning ability. 
Degree of mental retardation defined using activities of daily life 
Profound: a minimal capacity for functioning, needs nursing care; constant aid and supervision required. IQ<20 
Severe: Speech minimal; Can talk or learn to communicate. No profit from training in self-help. May contribute 
partially to self-maintenance under complete supervision later in life; IQ 20-34 
Moderate: Profits from training in self-help; can be managed with moderate supervision. IQ 35-49 
Mild: Can develop social and communication skills; minimal retardation and can be guided toward social 
conformity. IQ 50-69 
The  term  ‘Mental  Retardation’  in DSM-IV is now replaced by  the  term  ‘Intellectual  Disability’ in DSM-V. 
Statement of Special Educational Needs (SEN): In England & Wales, following a statutory assessment by 
local  authority,  a  ‘statement  of  SEN’  will  be  prepared  to    set  out  what  special  help  the  child  needs,  and  to  
consider the views and wishes of the child and their parents. The SEN statements consist of 6 essential 
parts as outlined below. The local educational board usually arranges for statutory assessments and 
initially issues a proposed statement, upon which the parents are invited to comment. The final statement 
has a legally binding effect on the board. It is possible to ask for reassessmeents to amend the statements.
