“…Even when FSS is implemented with modest fidelity, improvements in student outcomes have been achieved (Walker et al, in press). However, a growing literature supports the importance of intervention fidelity for long-term program effectiveness (e.g., Arkoosh et al, 2007;Barber, Crits-Christoph, & Luborsky, 1996;Duchnowski, Kutash, Sheffield, & Vaughn, 2006;Joyce & Shower, 2002;Luborsky, McLellan, Woody, O Brien, & Auerbach, 1985;Sterling-Turner, Watson, & Moore, 2002;Wilder, Atwell, & Wine, 2006). When a systematic intervention program is faded (in the case of FSS from coach to teacher), the student is likely to continue to behave well for a period of time even if the intervention is not implemented with fidelity.…”
