School master scheduling software compared
Schools build a master schedule in one of five ways: the scheduling module in their student information system, standalone timetabling software, a spreadsheet, a physical scheduling board, or a dedicated builder such as nOS. To choose, ask whether it builds from your course requests, tells you why a request missed, and gets the schedule back into your SIS.

How the options compare
| SIS scheduling module | Standalone timetabling software | Spreadsheet | Scheduling board | nOS | |
|---|---|---|---|---|---|
| Builds from course requests | Usually. Check which tools your version includes. | Some do. Many build class and teacher timetables only. | No. You place sections and students by hand. | No. You place sections by hand and students afterwards. | Yes, from your requests, sections, teachers, rooms and rules. |
| Explains unplaced requests | Conflict reports are common. How much they say about why varies. | Varies by product. | No. You find the misses yourself. | No. | Yes. Each one gets one of 12 plain-English reasons. |
| Rules in plain English | Set on constraint and settings screens. | Varies by product. | Notes you keep. Nothing checks them. | In your head or on a list. Nothing checks them. | Yes. Written as sentences, each marked hard or soft. |
| Sends the schedule back to the SIS | Not needed. It’s already there. | Usually as an export file. Check which systems it supports. | By hand, or as an import file you build. | Typed in by hand. | Depends on the system: over its API, as an import file, or as a reviewed handoff file. See the list. |
| Published price | Usually not. Ask whether scheduling is included or an add-on. | Some publish prices. Others quote. | You already own it. | The cost of the board and pieces. | Yes, on the pricing page. |
| Free trial | Not usually offered on its own. | Often. | Not needed. | Not needed. | Yes. One hour, the whole product, on your own data. |

Does it build from your course requests?
A master schedule exists to give students the courses they asked for. A tool that builds from course requests places sections and students together, so it can count how many requests it filled.
A timetabling tool that only places classes and teachers leaves the students to you. That can be fine for a school where every student in a grade takes the same courses.
Will it tell you why a request didn’t fit?
Every schedule leaves some requests unplaced. What matters is whether you can see why: the class is full, it clashes with another class, or it isn’t offered for that grade.
Ask to see the list of unplaced requests on a real build, and whether it says what to change.
Can you write your rules the way you’d say them?
Every school has rules: a teacher who only works mornings, two courses the same students take, a lab that needs a lab. Find out how those are entered, and whether the tool tells you when two rules contradict each other.
How does the schedule get back into your SIS?
Your student information system holds enrollment, grades and attendance, so the finished schedule has to end up there. Ask exactly how: over the system’s API, as a file someone imports, or typed in by hand.
Can you try it on your own data?
A sample school always schedules well. Try the tool on your own students, courses and rules before you commit, and check what the price covers.
The tools schools use
These are the names that come up most when schools talk about master scheduling. Each line describes what the vendor says on its own pages.
- PowerSchool. PowerSchool SIS schedules next year in PowerScheduler, where a school builds the master schedule and loads students into it from their course requests.
- Infinite Campus. The Infinite Campus SIS includes scheduling tools such as the Scheduling Board, Course Planner and Requests and Rosters. Its older Schedule Wizard was removed in August 2024.
- Skyward. In Skyward’s SIS, students request courses, and staff lay out the master schedule on a drag-and-drop board before students are scheduled.
- Synergy. Edupoint’s Synergy SIS has mass scheduling, and offers a Master Schedule Builder that works from course requests, staff and rooms.
- Rediker. Administrator’s Plus has a Master Schedule Builder that can place singletons first, lock courses in place and compare saved builds.
- aSc TimeTables. Timetabling software with an automatic generator, as a Windows app or in the browser. Its free trial does everything except export.
- Tes Timetable (Edval). Edval began in Australia and is now part of Tes. It builds, staffs and rooms timetables, automatically or by hand.
- TimetableMaster. A web timetabling platform with a free trial. It says students can pick courses and it then creates sections and schedules.
- Abl. Scheduling software and guidance for districts, focused on how time and staff are used. Abl became part of BetterLesson in 2025.
- FET. A free, open-source program that generates school timetables automatically.
- Spreadsheets and boards. Many schools still build by hand. A board lets you see the whole schedule and move a piece back, but it keeps no record and can’t check a student’s day.
- nOS. Builds the master schedule from course requests, explains every request it couldn’t place, and connects to student information systems including PowerSchool, Infinite Campus and Skyward.
Common questions
What is the best master scheduling software for schools?
It depends on your school. If your SIS scheduler already gives you a schedule you’re happy with, keep it. If you need students placed from their requests and a reason for every miss, look at tools that build from course requests, and try each one on your own data.
Do we have to replace our student information system to use a different scheduler?
No. Your student information system stays the record for enrollment, grades and attendance. A separate scheduler reads your data from it and hands the finished schedule back, or gives you files to import.
Is timetabling software the same as master scheduling software?
They overlap. Timetabling software often places classes, teachers and rooms. Master scheduling in most US middle and high schools also places each student from their course requests.
Can a spreadsheet or a scheduling board still work?
For a small school with few electives, yes. A spreadsheet can hold a schedule but can’t search for one. A board can be rearranged, but it keeps no record of why and can’t check a student’s day.
How much does master scheduling software cost?
It varies. SIS scheduling modules are usually priced inside the SIS contract, and some standalone tools publish their prices. nOS publishes its price per enrolled student on its pricing page.
