SummaryComments about sensitivity to changeChildren's PPVT scores improve following intervention, including both direct vocabulary instruction and a language/literacy intervention delivered in Head Start classroom (Coyne, McCoach, & Kapp, 2007; Wasik, Bond, & Hindman, 2006).
General remarksPPVT was standardized using a demographically representative U.S. sample of over 5,500 individuals ages 2.5-90+. It should be noted that, among low-income families, the PPVT seems to identify more children as having language delays than do other measures of language ability (Qi, Kaiser, Milan, & Hancock., 2006).
