According to AAMD and APA what is the I. Q. range of severe mental retardation children ?

Question

Accepted Answer

Severe mental retardation, as classified by the American Association on Mental Deficiency (AAMD) and the American Psychiatric Association (APA), is characterized by an IQ range of 20 to 35. This classification is based on standardized intelligence testing and is used to identify individuals who require significant support in daily living and learning activities due to their cognitive limitations.

1. **Explanation for Option 3 (20 to 35):** 
   - The IQ range of 20 to 35 is designated for severe mental retardation because individuals within this range typically exhibit significant developmental delays and require extensive support for daily functioning. They may have limited communication skills and need assistance with self-care and social interactions. This classification helps in determining the level of care and educational interventions needed to support these individuals effectively.

2. **Why Option 1 (52 to 67) is incorrect:**
   - The IQ range of 52 to 67 falls under the category of mild mental retardation, not severe. Individuals in this range can often acquire academic skills up to a sixth-grade level and may live independently with some support. Therefore, this range does not align with the characteristics of severe mental retardation.

3. **Why Option 2 (36 to 51) is incorrect:**
   - The IQ range of 36 to 51 is associated with moderate mental retardation. Individuals in this range can learn basic communication and self-care skills and may perform simple tasks under supervision. This level of functioning is higher than what is observed in severe mental retardation, making this option incorrect for the given classification.

4. **Why Option 4 (below 20) is incorrect:**
   - An IQ below 20 is classified as profound mental retardation, which is more severe than the severe category. Individuals with profound mental retardation require constant care and supervision and have very limited communication and self-care abilities. This classification is distinct from severe mental retardation, which is why this option is incorrect for the question.

In conclusion, Option 3 (20 to 35) is the correct answer as it accurately represents the IQ range for severe mental retardation according to AAMD and APA standards.
