The PLAC is designed as a criterion-referenced tool to assess play skills and language acquisition of children ages 2-7 and provide a behaviorally-based curriculum to establish or expand a child’s pretend play repertoire. The PLAC was developed from extensive review of the research on the developmental sequence of play, language acquisition and behavioral interventions. Additionally, data were collected and analyzed from research conducted at ACI Learning Centers’ on the developmental sequence of play and the implementation of the PLAC to formulate this assessment and curriculum tool.
