AttendanceEvent

There are several pre-defined attendance patterns that can be randomly applied to a given student. Generally the special attendance profiles are only applied to students with low performance profiles – 50th percentile or below. Absent a special attendance profile, a standard attendance profile is applied based on the student's performance index. Special profiles include:

  • Regularly absent on a specific day of the week
  • Regularly absent for the first period(s) of the day
  • Regularly absent for the last period(s) of the day
  • Regularly tardy for the first period of the day
  • Frequently tardy to random periods throughout the day


Depending on the profile chosen for the student, absence/tardy events are generated according to a Poisson process using absence/tardy rates defined in the attendance profile. Generally the attendance and tardy rates should trend to the average rates configured via XML, though outliers with particularly bad attendance and the random process itself mean that the overall attendance rate won't exactly match the configured average values.

Unless otherwise specified in the Config XML file, the default attendance rate is 93% (per NCES); the default tardy rate is 1%.
