WHAT IS INTELLECTUAL
DISABILITY?
Children with
intellectual disability show difficulties with thinking, learning,
communication (both verbal and non-verbal), memory, problem solving,
judgment and social functioning. Intellectual disability is
diagnosed if a child's intellectual ability (IQ) is notably below
average and shows severe limitations in at least two areas of
adaptive functioning.
Significantly below average
intellectual ability refers to an IQ score of 70 or less
as measured by standardised tests. An IQ score of 70 is
two standard deviation (1 standard deviation = 15 IQ points)
below the mean, occurring in approximately 2% of all children.
Limitations in adaptive functioning refer to skills
necessary for everyday living, such as communication, self care,
memory, social skills, problem solving and work/study
skills.
Some children develop slower than others and may
show a delay in one or more developmental areas. This is not intellectual disability and children
with delay in one or more areas of functioning can still
achieve their required milestones, even if at a later
stage. |
