ABSTRACT – The Smart Leave Request Management

System is a mobile application developed using Flutter and Firebase to automate the leave approval process in educational institutions. Students can submit leave requests with selected dates, leave type, and custom timings. The request is first reviewed by the Incharge and then forwarded to the HOD for final approval. The system uses Firebase Authentication for secure login and Firestore for real-time data storage and status tracking. This application reduces paperwork, improves transparency, speeds up approvals, and provides an efficient digital solution for managing student leave requests.

INTRODUCTION

The Smart Leave Request Management System is a mobile application developed to simplify and digitize the student leave approval process in educational institutions. Instead of using manual paperwork, students can apply for leave through the app by selecting the date, leave type, and reason. The request is reviewed by the Incharge and then forwarded to the HOD for final approval. The system uses Flutter for the frontend and Firebase for authentication and database management. This application improves efficiency, reduces delays, and ensures transparency in the leave approval workflow.

LITERATURE SURVEY

• Alade, Samuel Mayowa et al. ( 2022 ) presented a Web Based Leave Management System which emphasizes efficiency in leave tracking and history maintenance
• Abubakar Adamu ( 2020 ) in Employee Leave Management System demonstrated the automation of leave request and approval in institutional settings
• Praveen. T, Vetrivel H.M, Arumugasamy B(2020)built an Online Leave Management System for colleges allowing students to apply leave, check status, and cancel their leave

  .

• Mohammed & Rahman (2021) proposed a mobilebased leave system with SMS notifications, but did not support real-time push notifications or advanced role-based dashboards.
• Li & Wang (2021) implemented a blockchain-based secure leave system, improving data integrity but lacking mobile usability and instant notifications.
• Srinivas & Rao (2022) developed a college leave system with conditional approvals, but without proper multi-level approval and push notification support.

Drawback: Several papers highlight automation and cloud support, but many lack features like multi – level approval (e. g., class advisor HOD principal), role based dashboards, and real – time notifications tailored for educational institutions

PROBLEM STATEMENT

In many colleges, the permission approval process is manual, paper-based, and time-consuming. Students must physically submit applications, and faculty members face difficulty tracking multiple requests, leading to delays, miscommunication, and lack of transparency.

Existing digital solutions often lack academic-specific workflows, multi-level approvals, real-time notifications, and proper record management. Therefore, there is a need for a mobile-first, role-based Smart E-Permit System that streamlines leave requests, enables instant approvals, ensures transparency, and maintains secure digital records.

OBJECTIVE

• To digitize and automate the traditional paper-based permission process in colleges.
• To implement a structured multi-level approval workflow (Student Incharge HOD Admin).
• To provide role-based dashboards for students, faculty, HOD, and admin.
• To enable real-time notifications for request submission, approval, and rejection.
• To maintain secure digital records of all leave requests for tracking and analysis.
• To support document upload for valid leave verification.
• To improve transparency, efficiency, and accountability within the institution.

EXISTING AND PROPOSED SYSTEM

1. Existing System
   • The permission process is paper-based and handled manually.
   • Students must physically submit applications and collect signatures from faculty members.
   • Approval process is slow and depends on the availability of staff.
   • Prone to errors, misplacement of documents, and lack of proper record maintenance.
   • No centralized database to track past or pending requests.
   • Students have no real-time updates about their request status.
   • Generic online forms (if used) lack structured multi-level approval and role-based control.
   • Limited transparency and accountability in the workflow.
2. Proposed System
   • A fully digital, mobile-first Smart E-Permit System with secure login.
   • Role-based access for Student, Incharge, HOD, and Admin. Students can submit leave requests online with document upload support.
   • Multi-level approval workflow (Student Incharge

     HOD Admin).

   • Real-time notifications for submission, approval, and rejection.
   • Centralized database for secure storage and tracking of all records.
   • Dashboard analytics for admin to monitor request statistics and trends.
   • Faster processing, improved transparency, and reduced paperwork.
