Close a year

Locks every write on that year — fees, attendance, exam results, salary — frozen. Re-opening requires Correction Mode (audit-logged).

1. Settings → Close Academic Year → pick the year to close.
2. Pre-close checklist runs: any pending salary, unsubmitted attendance, open approvals?
3. Acknowledge pending items (or clear them first).
4. Type the principal mobile last-4 to confirm.
5. For MID-YEAR close (more than 30 days remain in the year): an additional typed phrase is required — "I confirm closing academic year 2025-26 mid-year today with N days still remaining and I take responsibility". Prevents accidental closes.
6. Tap Lock Year.
