Understanding Attendance Requirements
Why Attendance Matters
Regular school attendance is crucial for academic success. Students who miss school frequently fall behind in coursework and are at higher risk for dropping out. Many schools and districts have minimum attendance requirements for course credit.
Common Attendance Policies
Most schools require 90% attendance (missing no more than 18 days in a 180-day school year) to pass courses. Some districts have stricter requirements of 93% or 95%. Chronic absenteeism is typically defined as missing 10% or more of school days.
Excused vs. Unexcused Absences
While this calculator doesn't distinguish between excused and unexcused absences, many school policies do. Excused absences (illness, family emergency, religious observance) may be treated differently than unexcused absences in terms of academic consequences.
Intervention Strategies
When students approach attendance thresholds, schools often implement interventions like parent conferences, attendance contracts, or referrals to support services to address underlying causes of absenteeism.
Frequently Asked Questions
How is attendance percentage calculated?
Attendance percentage = (Days Present ÷ Total Days) × 100. Days present equals total days minus days absent. For example, if a student was present 162 out of 180 days, that's (162 ÷ 180) × 100 = 90%.
What is considered good attendance?
Generally, 95% or higher is considered excellent attendance (missing 9 or fewer days in a 180-day year). 90-94% is acceptable, 85-89% is at-risk, and below 85% is considered chronic absenteeism requiring intervention.
