“…However, solely relying on teacher nominations to identify at-risk students presents a number of concerns. These include: (a) teachers underreporting behavioral and emotional problems (e.g., Del’Homme, Kasari, Forness, & Bagley, 1996; Lopez, Forness, Bocian, MacMillan, & Gresham, 1996), (b) differences in student referral rates depending on a teacher’s subjective understanding of students’ teachability (Gerber & Semmel, 1984; MacMillan, Meyers, & Morrison, 1980), (c) delayed referral in the identification of behavior problems compared with other academic concerns (Del’Homme et al, 1996; J. W. Lloyd, Kauffman, Landrum, & Roe, 1991), and (d) the lack of consistency and teacher understanding regarding how problematic a behavior should be prior to a referral (Tilly, 2008).…”
