The purpose of this study was to provide initial evidence of the effectiveness of Check-In/Check-Out-High School (CICO-HS) on high school student outcomes. Check-In/Check-Out-High School is a version of CICO, an established Tier 2 intervention designed to improve student academic and social behavior, adapted to increase effectiveness and feasibility in high schools. Key adaptations in CICO-HS include increased student agency through goal setting and self-rating, and increased efficiency through use of a mobile application for data collection, progress monitoring, and family communication. This randomized controlled trial (RCT) was conducted during the 2021–2022 school year and included 14 ninth grade students in one public high school in the Pacific Northwest. Students were randomly assigned to receive CICO-HS or a waitlist/control condition. Although underpowered, the RCT results showed meaningful improvements (small to moderate effect sizes) in student attendance (unexcused tardies and absences) and teacher ratings of student academic and social behaviors. Moreover, students and school personnel rated CICO-HS components as being socially acceptable to implement in high school. Implications for future research to replicate and expand study findings and for practice to scale up CICO-HS with fidelity in high schools are discussed.

高中签到/签出 (CICO)：小型随机对照试验的结果

本研究的目的是提供高中签入/签出 (CICO-HS) 对高中生成绩有效性的初步证据。高中签到/签出是 CICO 的一个版本，CICO 是一项既定的二级干预措施，旨在改善学生的学业和社会行为，并适应提高高中的有效性和可行性。CICO-HS 的主要调整包括通过目标设定和自我评分增强学生的能动性，以及通过使用移动应用程序进行数据收集、进度监控和家庭沟通来提高效率。这项随机对照试验 (RCT) 在 2021-2022 学年进行，纳入了太平洋西北地区一所公立高中的 14 名九年级学生。学生被随机分配接受 CICO-HS 或候补名单/对照条件。尽管力度不够，但随机对照试验结果显示，学生出勤率（无故迟到和缺勤）以及教师对学生学业和社会行为的评分有显着改善（小到中等影响大小）。此外，学生和学校工作人员认为 CICO-HS 组件在高中实施是社会可接受的。讨论了对未来研究复制和扩展研究结果的影响，以及对在高中保真地扩大 CICO-HS 的实践的影响。
