Schools continue to rely on disciplinary exclusions as a consequence for behavioral rule violations, despite evidence that removing students from instruction for discipline purposes is associated with poor behavioral, academic, and social outcomes. School-wide positive behavior interventions and supports (SWPBIS) is one multitiered support framework used to prevent behavior problems while developing effective and efficient systems for intervening with students who require more support. Prior research suggests implementing Tier 1 of SWPBIS with fidelity is associated with reductions in disciplinary exclusions. In this study, we evaluated the additive effects of implementing Tier 1 and advanced tiers (i.e., Tiers 2 and 3) with fidelity compared with Tier 1 alone for 558 schools in California. Results indicate schools implementing all three tiers with fidelity had significantly lower rates of students receiving one out-of-school suspension, out-of-school suspension incidents, and students referred to law enforcement. We also discuss implications and recommendations for future research.

尽管有证据表明，出于纪律目的将学生从教学中除名与不良的行为，学术和社会成果相关，但学校仍继续依赖纪律处分作为违反行为规则的结果。全校范围内的积极行为干预与支持（SWPBIS）是一种多层支持框架，用于预防行为问题，同时开发有效，高效的系统来干预需要更多支持的学生。先前的研究表明，忠实地实施SWPBIS的方法1与减少纪律处分有关。在这项研究中，我们评估了加利福尼亚州558所学校实施保真的1级和高级等级（即2级和3级）与单独1级相比的附加效果。结果表明，实施所有三个级别的学校的忠实度大大降低了学生接受一门校外停学，校外停学事件以及转介执法的学生的比例。我们还将讨论对未来研究的影响和建议。
