Running a school means juggling lesson plans, timetables, attendance, behaviour notes, and grades all at once; Gibbon gives teachers, students, parents, and administrators one shared web system for that daily work. Teachers build lessons from reusable Smart Blocks, assemble them into units with learning outcomes, set and collect homework online, and grade the results in a colour-coded markbook that stays linked to every class. The timetabling engine builds schedules from reusable day structures, ties them to real calendar dates, handles exceptions, books rooms and facilities, and shows every student and teacher exactly where they should be. Attendance can be taken by form group, class, or individual student, with future absences recorded ahead of time and reports ready for emergencies or truancy follow-up. Behaviour records log the good alongside the bad using your school's own descriptors and severity levels, notify form tutors when something needs attention, and surface patterns across a student's history. Each student's profile pulls timetable, attendance, behaviour, library, and assessment information into one page, while activities sign-ups, a school-wide resource library, and departmental scope-and-sequence views keep the wider community connected. Because every module can be switched on or off per role and extended with community modules, the same platform fits a small primary school and a large secondary school in 26 languages.

Report cards, attendance rosters, class schedules, discipline logs, and fee statements all live in one browser-based system with RosarioSIS, an open-source student information system for K-12 schools and similar institutions. Administrators define marking periods in up to three tiers, set grade levels and daily periods, and search students by gender, grade level, schedule, absences, GPA, or class rank. The scheduler places whole classes or a single student, and runs in test mode each time a student's requests are saved, so conflicts can be resolved with the student still in front of you. Teachers keep a weighted gradebook with grade ranges, progress reports, report cards, and transcripts, take attendance electronically, and use the eligibility feature to flag who may join athletic or academic activities. Discipline logs, student billing with fees, payments, balances, and statements, food service, and accounting complete the core modules. Parents and students get their own portal, new families can register online, listings export to Excel, CSV, or XML, and charts and PDF documents support decisions and paperwork. The interface adapts to tablets and phones and is translated into a dozen languages. Add-on modules bring email, library, hostel, Jitsi Meet video rooms, and Moodle integration.
