Targeted Tier 2 interventions are critical to supporting students with challenging behavior and decreasing the resources associated with highly individualized and intense interventions. This study extends findings from recent single-case design studies and case example applications of the Tier 2 Identification and Intervention framework with the first large-scale evaluation of school-level outcomes following district implementation. We employed a pretest–posttest design within one large urban school district (N = 23,042 students) to evaluate school-level discipline outcomes for elementary schools who received training and coaching on the Tier 2 framework. Fidelity (i.e., Tiered Fidelity Inventory) and school-level demographics (e.g., poverty status, race) were entered as covariates into the generalized linear models. Results indicated statistically significant decreases in office discipline referrals and in-school suspensions for schools with adequate Tier 2 fidelity. Implications, limitations, and future directions are discussed.

有针对性的第2层级干预对于支持学生具有挑战性的行为并减少与高度个性化且强度大的干预相关的资源至关重要。这项研究扩展了最近的单案例设计研究的结果以及方法2识别和干预框架的案例应用，并在学区实施后对学校水平的成果进行了首次大规模评估。我们在一个大型城市学区（N= 23,042名学生），以评估接受第2层框架培训和辅导的小学在学校一级的学科成果。将保真度（即分层保真度库存）和学校水平的人口统计数据（例如，贫困状况，种族）作为协变量输入到广义线性模型中。结果表明，具有足够的2级保真度的学校，办公室纪律转介和学校停职的统计结果明显减少。讨论了含义，局限性和未来的方向。
