“…In particular, students from economically disadvantaged backgrounds, students from nontraditional (i.e., single or stepparent) families, and students who experience academic difficulties (e.g., poor grades, low test scores, grade retention, high absenteeism) drop out at higher rates relative to their higher achieving and more demographically advantaged peers (Astone & McLanahan, 1991;Barro & Kolstad, 1987;Garnier, Stein, & Jacobs, 1997;Goldschmidt & Wang, 1999). Similarly, males and students from ethnic and language minority groups have also been found to have higher dropout rates (Ekstrom et al, 1986; National Center for Education Statistics [NCES], 1992;Pallas, 1987;Rumberger, 1995).…”
