Even with the declining number of dropouts in Baltimore City, a focus on dropout prevention is essential. Recent research has emphasized the utility of an early warning system to inform prevention efforts. With this in mind, the Baltimore Education Research Consortium examined the 2000-01 cohort of sixth grade students (Class of 2007) from the Baltimore City Schools to ascertain whether there were indicators that predicted eventual dropout with a reasonable level of certainty, and identified enough students to justify intervention efforts. Also examined was a recent cohort of sixth graders from 2008-09 (Class of 2015) to determine if the prevalence of early warning indicators has changed. Four early warning indicators were identified for non-graduation for sixth graders: (1) Chronic absence (defined as missing 20 or more days of school); (2) Failing English, or math, or both and/or a failing average for English, math, science, and social studies; (3) Being at least one year overage (suggesting an earlier retention); and (4) Being suspended for three or more days. The examination reported a reduction in sixth grade early warning indicators of non-graduation as a positive sign for the district. Overall, sixth graders were much more likely to be on-track to graduation than they have been in the past. The report includes an appendix: Data and Methods.
