When a student fails to attend school for an extended day period, the excused and unexcused absences are tallied. Once 15 days of absences have passed, the student is dropped with the transfer out date being the day after the 15th absence. Keep the attendance codes recorded as a historical record.
You will need to update the W9XX when it is still attached to the current enrollment record or when it is attached to a previous school's re-enrollment record. If a student returns to the same school, you won't have to update the W9XX exit code. This code is reported on the EOY Student Record Collection extract.
If the student returns after a 15 day drop, use R418 with an Entry comment "Re-entry after 15 day drop."
