This report contains statistical data on absentee and withdrawal rates for the Eugene (Oregon) School District 4J. Included are data showing attendance patterns, as well as descriptions of coding practices for all elementary, junior high, and senior high schools in the district. The data, displayed in numerical tables, show that absentee and withdrawal rates fluctuate from year to year and quarter to quarter, with few district-wide trends emerging. The recording of attendance is not uniform for all district schools, and some of the procedures used lead to systematic underestimations of both absentee and withdrawal rates. (Author/DS)
