“…Much of this work has posited that dropping out of school is the culmination of cumulative risk factors over time, including difficulty reading or learning math, grade retention, school disengagement, and a variety of childhood behavior problems (Randolph, Fraser, & Orthner, 2006;Randolph, Rose, Fraser, & Orthner, 2004;Simner & Barnes, 1991;Woolley & Bowen, 2007). One comprehensive study followed a cohort of children from low-income families from birth to age 19 years (Jimerson, Egeland, Sroufe, & Carlson, 2000), and found that global indices of externalizing and internalizing (measured by the Child Behavior Checklist [CBCL]) during the first grade were predictive, to some extent, of high-school dropout (see also Alexander, Entwisle, & Horsey, 1997;Bridgeland et al, 2006;French & Conrad, 2001;Garnier et al, 1997).…”
