Resources
Useful whether or not you ever buy anything.
Guides, reference material and free tools for building a master schedule. Most of it works fine if you never talk to us.

Two things you can use right now, in a browser, without giving us an email address.
Upload a schedule and get a health report — pressure points, conflicts and the courses causing the most trouble. It runs entirely in your browser: the file is never uploaded anywhere. The shareable result link carries only scores and counts, never student data.
Run the auditThe complete nOS platform running on sample data — the solver, the Board, Scenario Lab, the Data Cleaner, exports, and nOS AI. Nothing to install, no account, nothing crippled. Exports work too.
Open the demoWhat building a master schedule by hand costs a school — in weeks, in uncaught errors, and in course access. Every figure sourced to published research.
ReadWhy fewer students means harder scheduling math, what the category gets wrong about schools under 600, and the questions small schools actually ask.
ReadThe realistic sequence, when in the school year to attempt it, what we need from you, and what happens if you decide to leave.
ReadWhy the magnet board genuinely works, the three things it cannot do, and how to get paper course requests into a computer.
ReadWhere a workbook stops scaling, what the research says about spreadsheet error rates, and how to bring the file you already maintain.
ReadKeeping your system of record while replacing the scheduling module — the round trip, the risks, and where the built-in module still wins.
ReadThe complete feature index on one page — no matrix, no asterisks, no "contact sales to learn more."
ReadEvery student information system nOS connects to, what each can pull, and which can receive a finished schedule back.
ReadHow student data is handled, where it is hosted, and who our subprocessors are.
ReadA side-by-side on build time, integrations, data handling and pricing.
ReadNot ours, and not written to sell anything. These are the sources this site leans on most.
Columbia Law School's Center for Public Research & Leadership. The most careful public study of how schools actually build master schedules — including a landscape analysis of what eight scheduling tools do and do not catch. If you read one thing on this list, read this.
Ray Panko's summary of decades of spreadsheet-error research, presented at the EuSpRIG conference. Relevant to anyone whose schedule lives in a workbook, and sobering regardless.
UC Berkeley's practical, vendor-neutral walkthrough of building a master schedule, including a clear treatment of singletons and doubletons.
The Association of California School Administrators on when the work actually happens across a school year. Useful for planning a switch.
Federal enrollment data. The source for how small most US private schools actually are — 85.7% enroll fewer than 300 students.
A running archive of documented, real-world spreadsheet failures. Grimly entertaining, and a good antidote to overconfidence about a workbook.
Longer writing on the craft of scheduling and the decisions behind nOS. The format and the editorial standards are already set — you can read both today.
