Disproportionate representation occurs when the percentage of an identified group enrolled in special education varies significantly from that group's overall percentage of the school population (Harry, 1994). Response to Intervention (RTI), a paradigm for educational intervention, is designed to minimize many factors contributing to disproportionality. The study examined disproportionality risk ratios for African American students, ages 6 through 21, who received special education services in a southeastern state supporting the RTI initiative during the 2006-2009 school years. Data suggest that African American students identified with a specific learning disability experienced increased referral and placement in special education in the three years corresponding to the initial RTI implementation efforts. Definitive conclusions about the fidelity of RTI implementation or effectiveness of intervention are beyond the scope of the current study, but disproportionality findings may be used as a comparative baseline for future research.
Intervention Disproportionate RepresentationDisproportionate representation, or disproportionality, occurs when the percentage of an identified group enrolled in special education varies significantly from that group's overall percentage of the school population (Harry, 1994). Disproportionality is a complex problem and a host of contributing factors has been cited in the literature to include societal factors, racism in education, classroom management failures, cultural unresponsiveness, varied definitions and implementation of special education, as well as biases in the educational and referral process itself (Armor, 2006;Artiles & Bal, 2008;Artiles & Trent, 1994;Coutinho & Oswald, 2000;Evans, 2005;Farkas, 2003;Harry & Klingner, 2007;Miller & Ward, 2008;Monroe, 2005;Patton, 1998;Singham, 2003;Skiba, Poloni-Staudinger, Simmons, Feggins-Azziz, & Chung, 2005;Warner, Dede, Garvan, & Conway, 2002). The negative implications of disproportionality include curriculum limitations, lower academic achievement, decreased participation in postsecondary education, and decreased employment opportunities for those identified and placed in special education (Patton, 1998).The Individuals with Disabilities Education Improvement Act (IDEA) of 2004 incorporated into oversight of special education mandate that states and districts analyze disproportionality data and take action to reduce imbalances (Bollmer, Bethel, GarrisonMogren, & Brauen, 2007). The primary measure of the incidence of disproportionality currently used in analyzing data is the risk ratio. A risk ratio "compares a racial/ethnic group's risk of receiving special education and related services to the risk for a comparison group," providing a measure of risk for an ethnic group of receiving special education services (Bollmer et al., 2007, p. 187). A weighted risk ratio is a more complex calculation in which a particular district's level of risk is divided by that of risk for all other students in that state (Bollmer et al., 2...
