(34 CFR 668.22(a))
For a student in a standard or nonstandard-term program, excluding a subscription-based program, the student is considered withdrawn if the student ceases attendance and is not scheduled to begin another course within a payment period or period of enrollment for more than 45 calendar days after the end of the module the student ceased attending. An exception may be available if the student is on an approved leave of absence. Students who plan to attend a future course past the 45-day timeline must provide written confirmation to the Financial Aid Department, even if the student is registered for the subsequent course.
Without confirmation of future attendance, a school must assume a student who has ceased attendance is a withdrawal, and it will begin the Return of Title IV Funds process.
