This study examines the relationship between student absentee patterns and the characteristics of ninth grade students in Clark County School District, Nevada. It is reported that the absentee patterns of junior high school students are significantly different from those of senior high school students. The length of continuous enrollment, and scholastic aptitude, reading, and math scores are reported to be significant factors regarding student absentee rate. Neither the sex nor ethnic background of students are reported to be significant factors regarding absenteeism. It is suggested that the data from this study could be used for a longitudinal comparative study to determine the impact of new attendance policies on student absentee patterns. (Author/JCD)
