What It Does

Course calendar building and schedule modeling

MasterSchedule.app is purpose-built for the planning phase — building and validating your master schedule before your SIS ever needs student data.

📅

Visual Schedule Builder

Assign courses to teachers and periods with a clear grid view. See your entire master schedule at a glance and make changes in seconds.

📥

Excel Import with Guided Walkthrough

Import your course catalog and teacher roster from Excel. A step-by-step guide walks you through the process so your data lands correctly every time.

✅

Conflict Detection

Spot teacher double-bookings and scheduling gaps the moment they happen — before they become problems for students.

🎓

Requirement Groups with Inheritance

Define base course requirements for a student type, then extend them for subgroups — honors, IEP, ELL — without duplicating rules. Changes to the parent flow down automatically.

🔒

Your Data Stays Yours

Every school is a completely isolated tenant. Other schools on the platform cannot see your data — not by convention, but enforced at the database level on every request. Role-based access, a 5-year audit log, and automatic data expiry keep you FERPA and GDPR compliant.

The Process

From setup to a validated schedule in three steps

Set Up Your School

Import your course catalog and teacher roster from Excel using the guided walkthrough, or enter them manually. Then define student types and requirement groups — with inheritance for subgroups like honors or IEP.

Build the Master Schedule

Assign each course to a teacher and period. The conflict detector flags problems in real time so you can resolve them before publishing.

Validate & Export

Run the validator to confirm your schedule meets the course requirements for every student type. Then export the completed schedule for your SIS or records system.
