ClassicalOS: the school operating system built for the classical tradition
AdArtes builds ClassicalOS, the school management platform designed from the ground up for classical Christian K–12 schools. Admissions, gradebooks, narrative evaluations, tuition, and board governance live in one system that speaks your school's language.
Your school isn't generic. Your software shouldn't be.
Classical schools have been left to choose between systems built for large public districts and a patchwork of spreadsheets, shared drives, and email threads. Neither one knows what a narrative evaluation is.
Spreadsheets everywhere
Enrollment in one sheet, grades in another, tuition in a third, board minutes in a shared drive. Nothing reconciles, and the person who built it is the only one who understands it.
Software that fights you
Letter-grade-only gradebooks with no place for recitation, virtue, or a written account of the whole student. The real records end up kept somewhere else.
Governance in the dark
Boards run on email chains and PDF attachments. Agendas, votes, policies, and the reports leadership needs live in five different places.
One system, from first inquiry to final transcript
Every part of running a classical school, connected — so your faculty can give their attention to formation, not administration.
Administration & Enrollment
Student and family records, a six-stage admissions pipeline, transcripts, absence requests, and the budget planner.

A block-based public website with enrollment forms built in, plus a startup workflow and template library for new schools.

Proven in the classroom, not just the demoThe parts no other platform has
These are the heart of a classical education, so they are the heart of the software.
Lesson plans by the Trivium
Teachers plan in the stages your school teaches in — telos, grammar, dialectic, rhetoric — and plans move through a submit, review, and approve workflow with deadlines and reminders.
Narrative evaluations & virtue
Write the whole account of a student alongside or instead of a letter grade, and record character formation against configurable virtue rubrics.
Memory work & Great Books
Track recitation across Scripture, Latin, catechism, and poetry, and run Great Books seminars — with families able to follow along at home.
Made by people who run a classical school
AdArtes exists to retrieve and promote historically classical education rooted in the Western tradition. ClassicalOS grew out of that work — built carefully, for one school, in the middle of a real school year.
Historically Classical
The Liberal Arts as arts — the Trivium perfecting language, the Quadrivium perfecting mathematical reasoning — integrating moral, intellectual, and spiritual formation.
Distinctively Christian
Orthodox Christianity affirmed through the historic creeds, with Scripture as authoritative and Christ as the unifying center of all knowledge.
Mission Focused
Serving the schools that form students in intellectual and moral virtue — for the glory of God.
