“…Yet schools and educators generally use acceleration very conservatively or not at all (Colangelo, Assouline, & Gross, 2004), particularly with gifted low-income or minority students who are underrepresented in many gifted programs (Bernal, 2002;Ford, Harris, Tyson, & Trotman, 2002;Grantham, 2003;Lee, Matthews, & Olszewski-Kubilius, 2008;Morris, 2002;Worrell, 2007;Wyner, Bridgeland, & Diiulio, 2007). Almost none of the research on acceleration to date has been conducted with low-income or minority students exclusively or with samples containing large numbers of these students in contrast to substantial studies on acceleration involving nonminority students (Colangelo et al, 2004;Gross, 2003;Janos & Robinson, 1985;Muratori, Colangelo, & Assouline, 2003;Rogers, 1991Rogers, , 2002Rogers & Span, 1993;Sayler & Lupkowski, 1992;Swiatek, 1993Swiatek, , 2002.…”
