The Preschool Language Scale-3, Spanish (PLS-3, Sp) is designed to assess receptive and expressive language skills in infants and young children in the areas of language precursors, semantics, structure, and integrative thinking skills.   The Auditory Comprehension Subscale is used to evaluate a child’s receptive language skills in the areas of attention, semantics, structure, and integrative thinking skills.  The Expressive Communication Subscale evaluates expressive language in the areas of vocal development, social communication, semantics, structure, and integrative thinking skills.  The mean standard score is 100 and the standard deviation is 15, therefore, performance between 85 and 115 is within the average range.
