Play assessment is increasing in popularity despite the lack of empirical support. The purpose of this study was to explore the use of play assessment with young children and determine its efficacy in determining cognitive levels of development. Eight 2-year-olds and eight 3 1/2-year-olds were observed playing in an unstructured format. Results indicated that Exploratory Play becomes more complex with age and is displayed more than Pretend Play in an unstructured play session. Children\u27s play primarily consisted of Exploratory Play, Pretend Play and Problem Solving and Planning Skills. Several of the Supple mental Subdomains measured by play assessment were not observed to occur in the spontaneous play format. A tendency for increasing complexity of play across time in session was also found
