GC Education Analytics K–12 Master Scheduler is a browser-based tool for building and refining master schedules, from elementary cohorts to high school block schedules. It supports elementary, middle, high, K–8, and 6–12 configurations. Scheduling models include self-contained, departmentalized, partner/platooning, split-band, traditional daily, A/B block, 4x4 semester, trimester, team-based, modified block, rotating drop, and multiple-variant schedules. Users can place sections by cohort and automatically generate elementary Art, Music, and PE rotations for homerooms. Constraints include teacher-period locks, unavailable times, room requirements, and course priorities. Real-time conflict counts and placement logs show where sections landed or why placement was not possible. Teachers and courses can be imported from CSV, and schedules exported as CSV for an SIS or printing. The scheduler runs in the browser without accounts or servers, keeps school data on the user’s machine, and saves work in browser IndexedDB. It uses a background Web Worker and offers teacher, room, and master-grid review views. The page describes it as a free beta with no sign-up, installation, or cost.
