Lumen LMS is a web based learning management system designed for schools, colleges, and universities. Its primary function is to centralize academic activities including course delivery, attendance tracking, timetable management, assignment submission, quiz administration, gradebook management, and parent communication into a single platform accessible via web browsers and mobile devices. The system adapts its terminology based on the institution type, using subjects and teachers for schools, and courses and professors for universities. The platform includes several core features. Attendance can be recorded with a single tap, with automatic absence notifications sent to students and their parents. The system provides a weekly timetable view for each student, highlighting current classes and displaying room assignments. Assignment workflows allow students to submit text and links, while teachers can provide scored written feedback. Quiz functionality includes auto grading, attempt limits, pass marks, and per question explanations. The gradebook supports CSV export for administrative use. Additional features include a parent portal for viewing grades, attendance, and upcoming homework; threaded course discussions with teacher highlighted answers; at risk student detection based on progress, scores, and attendance; and printable certificates with public verification links. The interface supports full Urdu language with right to left layout and includes a dark mode that follows device settings. Typical use cases involve daily classroom management for teachers, who can mark attendance, view timetables, grade submissions, and monitor student progress from a single dashboard. Students access their next unfinished lesson, today's classes, and pending assignments upon login. Administrators can view analytics across departments and manage large cohorts. Parents receive automatic absence alerts and can monitor their child's academic performance through the parent portal. The system is designed mobile first with an app style bottom navigation bar and can be installed on a device home screen without requiring an app store download. It is optimized for fast loading even on slow internet connections.
