“…The PPVT‐4 was selected to measure initial levels of receptive vocabulary in light of previous research indicating that initial receptive vocabulary levels are correlated with response to vocabulary instruction (Coyne et al, 2007; Loftus, 2008; Penno et al, 2002). Furthermore, research evidence links scores on all editions of the PPVT to later reading achievement (Carvajal, Hayes, Miller, Wiebe, & Weaver, 1993; Ollendick, Finch, & Ginn, 1974; Smith, Smith, & Dobbs, 1991; Williams & Wang, 1997). Therefore, scores on the PPVT may be interpreted as suggesting a “risk status indicator” for students who demonstrate low vocabulary.…”
