Weismuller, Penny C., et al. Elementary School Nurse Interventions: Attendance and Health Outcomes, The Journal of School Nursing, April 2007; vol. 23, 2: pp. 111-118. Regular school attendance is a necessary part of the learning process; student absenteeism has a direct association with poor academic performance. School nurses can influence student attendance. This study describes the impact of school nurse interventions on student absenteeism and student health. A retrospective review of 240 randomly selected elementary student health folders and attendance records was conducted. School nurses were involved with 75% of high-absence students as compared to 66% of low-absence students; they were also more involved with students who had previously identified health conditions.
