Master Scheduler
Your specials rotation, before your coffee's cold.
Built for elementary principals and APs. Auto-places the specials rotation, locks each grade's common prep, sets lunch periods, and flags conflicts in plain English. It creates a first draft and print/export packets — it is not a full SIS or HR staffing system.
The problem
Every fall, principals lose weekends to grids on whiteboards and color-coded post-its. One specialist double-booked on Tuesday means redrawing the whole thing — and nobody notices until Tuesday.
How Master Scheduler helps
Master Scheduler does the first draft for you so you can spend the time deciding, not drawing. Set up your school day, add grades and specials, mark lunch periods, and generate. Conflicts come with a sentence you can read out loud and a one-click fix. Same setup, same schedule, every time.
6 things, done properly
Specials rotation
Art, music, PE, library — rotated so nobody is in two rooms at once. Specialist double-bookings are flagged before they bite, and manual cell locks survive regenerate.
Common prep periods, locked
One protected common-prep period per grade, every day. Automate it or pick by hand; either survives regenerate.
Lunch placement
Mark teacher and student lunch periods on the bell schedule. Each teacher's lunch lands in a free allowed period, with conflicts flagged.
Plain-English conflict fixes
One conflict, one explanation, one suggested fix — including service warnings for push-in and pull-out (ENL, Speech, OT, AIS).
Print packets and CSV
Prep schedule, by-class view, cluster cards, Early Childhood track, conflicts, and services audit — printable with page breaks, or a CSV per view.
Your data stays on your device
Schedules live in browser storage. Save / Load JSON moves a draft to another browser or hands it to your AP.
Works on the devices your school already has
A laptop or desktop browser — the grids are wide. Works after the first load without internet.

Questions school leaders ask
How does Master Scheduler handle protected blocks like Fundations?
You define grade-level instructional blocks in Setup → Grade Blocks, mark Fundations as Protected core, and any pull-out service that would land on it gets flagged in the Services audit. The engine does not schedule student services yet — it flags them so you can.
What about pull-out services like ENL, Speech, OT, AIS?
You define services and their allowed blocks per grade. The Services tab shows a per-grade audit matrix, flags missing rules, and warns on pull-out from protected blocks. It is a planning and audit surface, not a session scheduler.
Where is my data stored?
On your device, in browser localStorage. Nothing is uploaded. Save / Load JSON gives you full export and import. Privacy reviewers can start with the districts and compliance handout.
Does it work for K–5? K–6? K–8?
Built around K–8, but you choose which grades exist for your building. 3K / Pre-K runs as a separate Early Childhood track with its own coverage.
Can I try it before paying?
Yes — Master Scheduler has a 14-day free trial. Build a full draft, read the conflict explainer, and print a packet first. The license applies only if you keep it.
What if my building doesn't fit any of this?
Email. Big Brain Labs is one teacher answering one inbox. Master Scheduler builds specials and common-prep rotations well; it does not claim to be a bell-by-bell whole-school master schedule.
