The Preschool Language Scale is a commonly used assessment by speech-language pathologists to diagnose language impairment in preschool aged children. This analysis examined responses on each subtest of the Preschool Language Scale, auditory comprehension and expressive communication, in primarily low-income, Hispanic preschool children. Results of the analysis indicated that expressive communication had a strong response/item analysis, however, auditory comprehension was not as strong. Speech-language pathologists should use caution in interpreting the results of auditory comprehension as it may overidentify or under identify low-income, Hispanic preschool children.
