Which level of mental retardation is indicated by an IQ of 34 or lower?

An IQ of 34 or lower is indicative of Severe and Profound Retardation, which reflects significant limitations in intellectual functioning and adaptive behavior. Individuals in this category typically have an IQ ranging from approximately 20 to 34, characterized by a need for considerable support in daily living activities and overall functioning.

Those with severe mental retardation often have difficulty with communication, self-care, and social interactions. They require assistance in most aspects of life and may have associated physical disabilities or health issues. This classification is important for understanding the level of support and intervention necessary for individuals with such cognitive limitations.

In contrast, other levels of mental retardation, such as moderate or mild retardation, correspond to higher IQ ranges and typically involve different degrees of adaptive functioning and independence. Intermittent retardation is not a commonly recognized category in the context of IQ classifications. This context helps clarify why the designation of Severe and Profound Retardation is appropriate for an IQ of 34 or lower.
