ICTSchool is an open-source school management system with built-in voice and SMS communication — not just another admin dashboard. Built on the ICTCore telephony framework, it lets schools call or text parents directly for fee reminders, attendance alerts, and emergency notices, all from the same system that handles enrollment, fees, timetables, and exams. Multi-branch support and white-label branding make it a fit for school chains too. Fully open-source — you own the code and the data.
