“…PSW methods typically require demonstration of a cognitive deficit that theoretically aligns with an achievement deficit (Alston-Abel & Berninger, 2018;Hale et al, 2008), but how such deficits are determined differs across models (e.g., normative vs. ipsative deficits; Stuebing, Fletcher, Branum-Martin, & Francis, 2012). There is a lack of empirical research, though, supporting the technical adequacy of such approaches to SLD identification (Kranzler, Floyd, Benson, Zaboski, & Thibodaux, 2016;McGill &Busse, 2017;Stuebing et al, 2012). Conversely, there is a growing body of research suggesting that PSW models do not result in reliable or valid SLD identification decisions (e.g., Kranzler et al, 2016;Miciak, Fletcher, Stuebing, Vaughn, & Tolar, 2014;Miciak, Taylor, Denton, & Fletcher, 2015;Stuebing et al, 2012;Taylor, Miciak, Fletcher, & Francis, 2017).…”
