One framework, every classroom
Every arc in the building is planned on the same four capacities and four domains, so a Grade 1 arc and a Grade 4 arc are recognizably the same kind of thing. Walkthroughs and PLC conversations get a shared vocabulary.
For school leaders
Inquiry planning your whole school can share.
Arc Builder gives every teacher the same framework, the same standards visibility, and the same planning shortcut, without flattening the way each of them teaches. Here is what that looks like for a principal, a curriculum lead, or a center director.
Standards coverage you can see
Lesson blocks are tagged with Common Core or state standards and Compositive standards. Arcs and lessons print cleanly for observations, portfolios, and accreditation binders.
Planning time returned
A teacher drafts an 8-week arc in an afternoon and each day's plan in a minute, then spends their time on the judgment calls: what to keep, what to change, what their class needs.
Professional development built in
Every hint, every phase, every standards tag teaches the Compositive model in context. Teachers new to inquiry learn it by planning with it.
How a pilot works
Three steps, no procurement cycle.

Tell us about your school
Use the form below: grades, number of classrooms, what you hope planning could look like.
- 2
Approve your teachers in one step
Compositive can approve every account from your school's email domain automatically, so teachers sign up and are in the same day. Individual approvals work too.
- 3
Set preferences, build a first arc, check in
Each teacher sets teaching preferences once, builds an arc around a real upcoming unit, and we check in after two weeks to hear what worked.
Questions leaders ask first
- Who owns the arcs and lessons?
- Your teachers do. Arcs are private to the teacher who made them unless they share one with a colleague. Compositive administrators can see content for support and approvals, and pilot-study participation is a separate, revocable consent.
- Is any student data involved?
- No. Teachers describe a class in general terms: size, day length, teaching style, resources. No rosters, names, or assessment data are collected.
- What does it cost?
- During the pilot, Arc Builder is free for teachers. Compositive will discuss terms for wider adoption with you directly.
- How is AI used, and what happens to our prompts?
- Arc Builder drafts arcs and lessons with a large language model working under Compositive's instructions. Prompts (your topics, class context, and preferences) are sent to the model provider only to produce the draft; they are not used to train the model, and no student data is involved.
- Which grades and settings?
- Age 3 through Grade 5 today: preschools and early childhood centers, elementary schools, homeschools and co-ops. Arcs run 4 or 8 weeks to match the Compositive domain rotation.
- What do teachers need to get started?
- A browser (Chrome works best), an email address, and a topic their class is curious about. Most teachers build their first arc in the first sitting.
