Which measure of general intelligence is most appropriate for a hearing-impaired child with an intellectual disability?

The Universal Nonverbal Intelligence Test™ (UNIT™) is the most appropriate measure of general intelligence for a hearing-impaired child with an intellectual disability due to its design, which minimizes the reliance on verbal communication. This test focuses on nonverbal tasks, allowing children who may experience communication difficulties, such as those with hearing impairments, to demonstrate their intelligence through nonverbal reasoning skills.

This is especially important for children with hearing impairments, as traditional verbal assessments might not accurately reflect their cognitive abilities due to potential limitations in language processing and communication. By using nonverbal measures like the UNIT™, the assessment can more effectively capture the child's true cognitive skills without the confounding factor of verbal ability.

The other options, while established measures of intelligence, either rely significantly on verbal components or may not be sensitive enough to accurately assess the capabilities of a hearing-impaired child. This makes UNIT™ uniquely suited for such assessments, helping to ensure fair and valid evaluation of the child's intellectual profile.
