We examined shifts in educators’ perceived knowledge, confidence, and usefulness, and actual knowledge of concepts in the Comprehensive, Integrated, Three-Tiered (Ci3T) model of prevention before and after participation in a practice-based professional learning series to design, implement, and evaluate a Ci3T model for their school. Participants completed the Knowledge, Confidence, and Use (KCU) survey prior to and at the conclusion of the year-long, six-part Ci3T Professional Learning Series. Results indicated that participants demonstrated statistically significant increases in perceived and actual knowledge, perceived confidence, and perceived usefulness of concepts measured, with effect sizes suggesting large effects. Implications for supporting educators in designing a Ci3T model of prevention to meet students’ educational needs using a practice-based professional learning series are discussed, along with limitations and considerations for future research.

全面，综合，三层（Ci3T）的预防模型提高教育者的知识，信心和实用性：专业学习的成果

我们参加了基于实践的专业学习系列以进行设计，实施之前和之后，研究了预防人员在综合，集成，三层（Ci3T）预防模型中感知的知识，自信和有用性以及概念的实际知识的转变。 ，并为其学校评估Ci3T模型。在长达一年的六部分Ci3T专业学习系列活动之前和结束之时，参与者完成了知识，信心和使用（KCU）调查。结果表明，参与者证明了所测概念的感知和实际知识，感知的信心和感知的实用性在统计学上显着增加，且效应量表明具有较大的效应。
