Assessing the effects of a school-based intervention on unscheduled school transfers during elementary school.

Raising Healthy Children is a cluster-randomized study of a school-based intervention aimed at preventing problem behaviors among children recruited into the project in the first or second grade of elementary school. Multilevel analysis was used to compare students in intervention and control schools with respect to whether they transferred out of their original schools. Students in intervention schools were less likely to transfer within the first 5 years of the project. A multilevel discrete-time survival model that included both time-varying and contextual variables revealed that the difference in hazard of transfer was greatest in the earlier years of the project.
