Prong 1 / Prong 2 (Intellectual Disability)

Definition

Many states, including Alabama, analyze intellectual disability claims in distinct parts or 'prongs.' Prong 1 typically addresses intellectual functioning (usually measured by IQ), and Prong 2 addresses adaptive behavior deficits. A defendant must generally satisfy both prongs to be found intellectually disabled.

Examples

• •The dispute in this case centers on Prong 1—whether Smith's IQ scores establish sub-average intellectual functioning—before even reaching his adaptive behavior deficits at Prong 2.
