Carolina Picture Vocabulary Test: validation with hearing-impaired students.

When mean Carolina Picture Vocabulary Test standard scores were compared with WISC-R Performance Scale IQs significant differences were observed. The Carolina test scores were also correlated with both Performance IQs and the Performance Scale subtest scores. Most correlations were minimal as the two tests were independent; only WISC-R Picture Arrangement scores correlated significantly with Carolina scores. These outcomes coupled with the technical limitations of the Carolina raise serious questions regarding its utility for hearing-impaired children.
