“…Among the numerous disability categories that may logically coexist with GT are, for example, those that are sensory, communicative (particularly speech related), emotional/behavioral, health and “other‐health” related (including attention‐deficit‐hyperactivity‐disorder), disorders at the mild end of the autism spectrum (e.g., Asperger syndrome), and SLD. Although prevalence data for twice exceptional students are limited (Bianco, 2005), it is estimated that as many as 540,000 such students exist nationwide (Karnes, Shaunessy, & Bisland, 2004), of whom perhaps 95,000 (17.6 percent) have SLD, comprising the largest subgroup of such students (Bianco, 2005). The underidentification of G/LD students (Brody & Mills, 1997; Krochak & Ryan, 2007; Morrison & Rizza, 2007) reflects the challenge in accurately assessing this dual exceptionality, largely owing to the necessity of these students satisfying criteria for two disparate and often mutually exclusive categories (Brody & Mills, 1997; Karnes et al, 2004).…”
