IQ 35/40 to 50/55
Trainable
Functioning level: Severe
IQ 20/25 to 35/40

Levels of support: Limited
Consistency, but time limited.
Levels of support: Intermittent
As needed
Levels of support: Extensive
Regular daily involvement, not time limited.
Levels of support: Pervasive
Consistant, high intensity, potential life sustaining nature.
What are high incident disabilities?
- Mild mental retardation, Specific learning disabilities, ADHD, and Behavioral disorders.
- Makes up larger percentage of students receiving SPED services.
- Most participate in an academic curriculum with appropriate modifications and accommodations.
What are low incidence populations?
- Includes persons with moderate, severe, and profound MR, autism, and multiple disabilities. Also includes people with severe sensory issues like deaf or blind.
- Smaller percentage of the population
- Students participate in a functional curriculum focusing on life skills for adulthood.
What is Down Syndrome?
- Trisomy 21: The failure of one set of chromosomes to separate at conception.
- Most common form of MR.
- Mosaicism: Uneven division that creates cells varying in chromosome numbers.
Factors that can cause Down Syndrome.
- Taking medications and drugs during pregnancy.

- Short stature
- Flat broad face with small ears and nose

- small mouth and short roof which may result in protruding tongue
- relaxed muscle tone
- delayed sexual development
- most have moderate MR
- problems with speech and language
- loss of intellectual functioning with advanced age
What is Fragile X?
- Results from a severe deficiency of the protein FMRP that is essential in developing brain functions.
- Second mort common form of MR
What are the physical traits of Fragile X?

What is Prader-Willi Syndrome?
- 70% of cases caused by deletion of the long arm of the parental chromosome on pair 15.
- The other 30% is caused by uniparental disomy: Both chromosomes on pair 15 contributed by the mother and none from the father.
- associated with mild MR and learning disabilities
Characteristics of Prater-Willi Syndrome.
