Each school year, roughly a thousand students drop out of Montgomery County (Maryland) Public Schools (MCPS). However, unlike other large, urban school districts where students who drop out skip school and are suspended often (Balfanz & Byrnes, 2010), students who drop out of MCPS are present in school; they just are not doing well academically. Fortunately, students who drop out of school exhibit a pattern of behaviors that are generally identifiable in advance of them dropping out of school completely, and these behaviors are referred to as Early Warning Indicators (EWIs). Because EWIs are signs of students disengaging from school, they provide MCPS with the opportunity to not only intervene with potential dropouts, but to also provide supports to students who are struggling with school that may not eventually drop out. By applying the Early Warning Indicators (EWIs) approach to Montgomery County Public Schools' student data, this report identifies the attendance, behavior, and coursework indicators of MCPS dropouts, along with recommendations. The report includes an appendix of additional tables.
