How important is attendance?
The attendance rate is important because students are more likely to succeed in academics when they attend school consistently. It’s difficult for the teacher and the class to build their skills and progress if a large number of students are frequently absent. In addition to falling behind in academics, students who are not in school on a regular basis are more likely to get into trouble with the law and cause problems in their communities.
