Question

which of these is a shared element of the idea and aaidd definitions of intellectual disability?
a prenatal onset of the condition
the concept of adaptive behavior
an iq score at least 4 standard deviations below the mean
a mandatory group administered iq test

Explanation:

Both IDEA (Individuals with Disabilities Education Act) and AAIDD (American Association on Intellectual and Developmental Disabilities) consider adaptive behavior as a key element in their definitions of intellectual disability. IDEA emphasizes the need for special education and related services due to limitations in adaptive behavior. AAIDD also highlights the importance of adaptive functioning in its framework. Prenatal onset is not a shared element as intellectual disability can have various onset times. An IQ score at least 4 standard deviations below the mean is not a common criterion (usually around 2 standard deviations). A mandatory group - administered IQ test is not a shared element as assessment methods can vary.

Answer:

The concept of adaptive behavior
