• “Mild Mental Disability” means that a child has:

– cognitive functioning at least two (2) but no more than three (3) standard deviations below the mean;

– adaptive behavior deficit at least two (2) standard deviations below the mean;

– a severe deficit in overall academic performance including acquisition, retention, and application of knowledge; and

– manifestation during the developmental period.

KAR 1:280 §1(37) 1

Typical Characteristics and Needs of Students Identified as MMD

• Need intermittent to limited support

• No apparent physical differences from non-disabled peers

• Mild to moderate developmental delays

• Identified in school setting:– Cognitive disability

most apparent

• Accelerated performer–Meets and rises

to challenges most obvious factor to recognize

• Performer– Does pretty much

what’s expected – Typical student

with MR

Abstract Thinker v. Concrete Thinker

• Abstract Thinker– Elaborates on

the concepts presented

– Anticipates the outcomes

– Applies relevance to circumstances

• Concrete Thinker– Very specific

response– Practical and

basic application

Challenged v. Systematic

• Challenged–Eager – Invites change–Exploratory– Innovative

• Systematic–Benefits from

routines–Prefers

Mental Retardation: Classifications

AAMR 1983 Classifications• Mild Mental Retardation• Moderate Mental

Retardation• Severe Mental Retardation• Profound Mental

Retardation

IQ Range• 50-55 to 70• 35-40 to 50-55• 20-25 to 35-40• Below 20-25

Prevalence

• 11% of all students with disabilities are classified with mental retardation

• 611,076 children aged 6-21• Approximately 2.5% (6 million) of the

general population would be classified as mildly retarded

• The remaining 0.5% (over 1 million) would fall into the range of moderate through profound mental retardation.

Common Causes of MR

• Genetic Conditions• Problems during pregnancy• Problems at birth• Health problems
