“…Early research examined potential implications of bias in teacher ratings of performance and referral patterns, but results were mixed (Cullinan & Kauffman, 2005;MacMillan, Gresham, & Bocian, 1996). Studies of assessment bias have also been equivocal, but the consensus appears to be that differential performance is not attributable to measurement bias (Skiba, Knesting, & Bush, 2002). Others have studied educational processes, including referral and multidisciplinary teaming (e.g., Harry, Klingner, & Hart, 2005;Wilkinson, Ortiz, Robertson, & Kushner, 2006); and though scholars have identified shortcomings-particularly frequent disregard for legal disability criteria-researchers have not established links and causal relations to disproportionality.…”
