What MasterSchedule.app is

MasterSchedule.app helps K–12 schools build and validate a master course schedule before using their student information system (SIS). Its visual grid assigns courses to teachers and periods, and a guided walkthrough imports the course catalog and teacher roster from Excel. Real-time checks flag teacher double-bookings and scheduling gaps. Requirement groups can inherit from base groups, allowing groups such as honors, IEP, or ELL to extend those requirements. The validator checks requirements for every student type, and completed schedules can be exported for an SIS or records system. The listed data exchange options are Excel import and CSV export; SIS integration is not required. The app is intended for school staff and does not create student accounts or collect students’ personal information. The site describes each school as an isolated tenant, with database-level access isolation on every request. It also describes role-based access, a five-year audit log, automatic data expiry, and FERPA- and GDPR-compliant storage. The School Plan costs $100 a year per school and includes unlimited courses and teachers, CSV export, multi-admin access, and a five-year audit log. The pricing page says a trial will be available at the School Plan launch.
