“…More contemporary studies consistently show that mean reading age peaks at 12 years for juvenile offenders (Alm & Andersson, 1995; Grigorenko et al, 2015; Snowling, Adams, Bowyer-Crane, & Tobin, 2000; Wheldall & Watkins, 2004), and depending on the delinquent population, up to half may experience reading and literacy deficits (McMackin, Tansi, & Hartwell, 2005; Vacca, 2008). In one large-scale study, Grigorenko and colleagues (2015) found that almost 25% of all youth detained in Connecticut in 1 calendar year displayed learning deficiencies, 4 times the rate in the general population. By second grade, almost half of all students who will later become delinquents have experienced reading delays (Meltzer, Levine, Karniski, Palfrey, & Clarke, 1984), and by adulthood, more than 60% of inmates have no better than a sixth-grade reading level (Alm & Andersson, 1995; Vacca, 2004).…”
