What is it?: Classic VP is weak for identifying lexical growth in young children (Horst & Collins, 2006), especially in the crucial K-2 phase. VP-Kids matches children's texts against 10 modified 250-word lists generalized from several empirical studies of children's oral productions (Murphy 1957; Johnson 1971; Hopkins 1979; Moe et al 1982) by Stemach & Williams.
