Student Leave Management

Teachers serve as the first tier in the 3-level digital leave approval chain — reviewing, approving, rejecting, or returning leave applications from students in their allocated and class-teacher classes, with a full audit trail of every decision.

1. The 3-Tier Leave Approval Chain

Every student leave application flows through three levels of review before becoming final — ensuring proper oversight while keeping the process fast and fully digital.

• Teacher (First Level): Reviews the leave application for basic validity. Checks if the reason is appropriate, if dates are reasonable, and if the student has attached required documents. Can Approve, Reject, or Send Back for correction.
• HOD (Second Level): Receives teacher-approved applications and gives the final decision — for medical leaves, extended absences, or any application requiring departmental authority.
• Automatic Attendance Protection: When a leave is fully approved (HOD level), the system automatically marks the student's attendance as "On Leave" for those dates — protecting their attendance percentage.

2. Leave Application Details

When a student submits a leave application, the teacher sees a detailed view of the request — everything needed to make an informed decision.

2.1 Application Information

• Student Name, Class, Roll Number, and Photo
• Leave Type: Medical / Personal / Family Emergency / Event Participation / Other
• Leave Dates: Exact start and end dates. Duration calculated automatically (e.g., "3 working days").
• Student's Reason: The written explanation the student provided when applying.
• Supporting Document: If the student attached a medical certificate, event letter, or other evidence — the teacher can view or download it directly.
• Current Attendance %: The student's current attendance percentage is shown — helping the teacher assess whether approving this leave will push the student below the minimum threshold.
• Attendance After This Leave: Predictive calculation — "If approved, this student's attendance will drop to 68.5%" — helping the teacher make an informed decision.
• Previous Leave History: A summary of past approved leaves in the current academic year — how many days total, and what types.

3. Teacher Actions on a Leave Application

3.1 Approve

• Clicking "Approve" forwards the application to the HOD for the second-level review.
• An optional comment field lets the teacher add a note for the HOD (e.g., "Student has a valid medical certificate — recommend approval").
• The student's application status changes to "Teacher Approved — Awaiting HOD" and the student is notified.

3.2 Reject

• The teacher enters a mandatory rejection reason (e.g., "Insufficient documentation provided" or "Repeated leave pattern — please consult class teacher").
• The application is closed. The student is notified of the rejection and the reason.
• The student cannot reapply for the same dates — but can appeal to the HOD directly in exceptional cases.

3.3 Send Back for Correction

• If the application is incomplete (e.g., no supporting document attached, incorrect dates), the teacher sends it back with specific instructions.
• The student receives the feedback and can edit and resubmit the application.
• This avoids outright rejections for fixable issues — ensuring fair, student-friendly processing.

3.4 Urgency Handling

• Leave applications that cover dates starting within 24 hours are tagged with an "Urgent" badge — prompting immediate teacher action.
• The teacher receives an in-portal notification for urgent leave requests, even when not actively browsing the leave section.

4. Leave History & Tracking

The teacher can review the complete leave history for any student in their class — useful for counselling, parent communication, and academic planning.

• Student-wise Leave Log: Open any student's profile to see all leaves applied, approved, and rejected across the current academic year.
• Class Leave Summary: A class-wide view — how many total leave days have been approved, how many applications are pending, and students with the highest leave count.
• Leave Calendar: A calendar view showing which students are on approved leave on any given day — useful for planning lectures and important activities.
• Export: Download the leave records in Excel format for departmental reports or HOD meetings.

5. Teacher's Own Leave Applications

Teachers also apply for their own leave through the same system — with the HOD as their approving authority.

• Apply for Leave: Select dates, leave type, and reason. Attach supporting documents if required by institution policy.
• Substitute Arrangement: Teachers can note which colleague will cover their classes during the absence — visible to the HOD in the approval view.
• HOD Approval: The HOD reviews the teacher's application and approves or rejects with comments.
• Leave Balance: The teacher can view their available leave balance (Casual Leave, Medical Leave, Earned Leave) — updated in real-time as applications are approved.
