"At the core of school improvement and education reform is an assumption so widely understood that it is rarely invoked:
Students have to be present and engaged in order to learn."
-Chang, Hedy & Romero, Mariajose, Present, Engaged & Accounted For:
The Critical Importance of Addressing Chronic Absence in the Early Grades,
National Center for Children in Poverty: NY: NY, September 2008. 
Because of this simple truth about school success, SUSD makes it a top priority to communicate with parents about the importance of regular attendance of our students.
