Excused and unexcused absences easily add up to too much time lost in the classroom. Students are at risk academically if they miss 10 percent of the school year, or about 18 days. Once too many absences have occurred, they can affect learning, regardless of whether absences are excused or unexcused. Before you know it, just one or two days a month can add up to nearly 10 percent of the school year. Some absences are unavoidable. Occasionally, children get sick and need to stay home. What is important is getting children to school as often as possible. Learn more at http://www.attendanceworks.
