Truancy is well documented as an indicator of high risk for drop-out and failure to graduate, as well as a risk factor for delinquency. This report provides a snapshot of truancy in District of Columbia Public Schools (DCPS) high schools and middle schools in 2010-11. School data on student absenteeism was combined with Census and crime data on school neighborhoods and students’ residential neighborhoods. In the 2010-2011 school year, 2,500 high school students were chronically truant in District of Columbia Public Schools; at four schools over half of the students were chronically truant. High school truancy rates were moderately related to poverty and crime in students' residential neighborhoods and to violence near school. But the absenteeism of students in eighth grade was the strongest predictor of high school truancy rates. Focusing on middle school attendance issues may therefore be the most effective means of lowering high school truancy rates. Appended are detailed middle school neighborhood tables.
