• School Absence Calculator — calculate current attendance and absence rates, see how many additional missed days would reach the common chronic-absence reference, and project year-end absences.
• Chronic Absenteeism Calculator — combine excused, unexcused, suspension, and other missed days and compare the total with a chronic-absence reference.
• Attendance Target Calculator — estimate how many consecutive attended days are needed to reach an attendance goal and compare additional-absence scenarios.
