This study used a short-term longitudinal design to examine the extent to which kindergartners': (a) peer relationships are associated with their school absenteeism; and (b) development of positive peer relationships vary as a function of their time spent in school. To address these aims, data were drawn from 801 kindergartners across 64 classrooms and 15 schools in a Midwest city in the United States. Results from covariate-adjusted regression models revealed that kindergartners' relational bonds were not predictive of their time away from school, and that their relationships with classmates were generally unaffected by absenteeism. There was, however, some indication that children's relationships with their classmates were more strongly predicted by their absenteeism for children from less educated households relative to children from more educated households.
