GC Education Analytics K–12 Master Scheduler vs Griddle

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.

Griddle is cloud software for school timetabling and daily organisation. Its timetable tools check data, report issues, and support automated building alongside manual changes; the engine can produce timetable solutions within two hours. AI line generation creates class combinations while accounting for school constraints and teacher and room requirements. Online course-selection forms apply curriculum rules and allow individual student exceptions. Flexible student groups, automatic enrolments, and class-list changes update student timetables. One setup can coordinate shared staff, spaces, students, and cross-campus classes. Griddle supports multiple period structures, including overlapping periods and teacher break rules across structures. Daily Organisation handles teacher absences and events. Events created in Compass appear automatically, and exam schedules can be published there; Griddle Exams can create extra sittings for special considerations. Multiple users can work on the same data simultaneously, with roles and permissions controlling access. Pricing is on request.
