Case Study · Danbury Public Schools
Curriculum written by teachers, with the paperwork carried for them.
Danbury Public Schools set out to give its curriculum writers, about thirty teachers, a way to write a year of career pathway courses without losing the summer to it, and without the quality falling apart by the last unit. This is the record of what was built beside those teachers, what they said, and the first measured result.
First measured result · observed June 29
The district's curriculum administrator reviewed a teacher's completed unit, with the standards and language-function tagging already carried by Trellis, in about fifteen minutes. By hand, that review ran an hour and a half. The teacher had built the unit in about two hours.

The problem
Every summer, the district hands teachers a course to write from scratch, often in a career field that is new to them. They get eighty paid hours, and the math does not work.
“We all come back and you get a mishmash of a thousand different things and they all look different.”
Bringing those drafts into one coherent shape falls to her, by hand, across every pathway in the building.
“That becomes the most ridiculous part of my job. Because it's impossible to do that work just based on the sheer number of things we have in the hopper.”
The work degrades on a predictable curve. The paid hours run out before the course is done, so the last units of the year arrive rushed and thin, and they are often handed to a different teacher to deliver. The standards, the district's own frameworks and the multilingual-learner tagging, the part teachers dread most, is where the quality slips first.
How Trellis was built
Trellis was scoped from one instruction the curriculum administrator gave.
“Take these five champions, find the commonalities in how they work and how their brain operates to create curriculum, and then make a tool that helps the other 25 catch up to them.”
The engine is the codified mental models of Danbury's strongest curriculum writers, plus the industry and policy context the other teachers need. The other 25 teachers start from the champions' patterns as their floor. Around that engine, four design rules came straight from the teachers:
- ·Carry the busywork in the background. The teacher writes in flow; the standards, Portrait, multilingual, language-function and assessment-type tagging happen underneath.
- ·Write first, tag last. Tagging as you go broke the teachers' flow, so tagging waits until the writing is done.
- ·Suggest, then confirm. Every suggestion comes with a confidence signal and shows where it came from. The teacher says yay or nay.
- ·One surface. Standards and resources dock right beside the writing field.
The teachers drew the line themselves. In an academy lead's words, it still tests your teachers. The judgment stays with the teacher.
Trellis was built by one person, fitted to Danbury's own templates and its strongest writers, in under four weeks. At the district's onboarding days, teachers were up and running in under an hour, and spent the rest of the day building curriculum.

In Danbury Public Schools, a unit curriculum review went from 90 minutes to 15.
What the teachers said
Trellis was tested in working sessions with teachers across the skill spectrum. These are their words.
“All that other stuff's done in the background. It's a godsend.”
“I felt like I had ADHD.”
“It looks really nice and it's definitely set the way I plan.”
“This app has changed since last time I looked at it. This part excites me a lot.”
“It still tests your teachers.”
“If I can have something make a suggestion, and then for me to say yes, yay or nay.”
“For me to give feedback in less than fifteen minutes, that would normally take me at least an hour and a half per unit.”

What Trellis produces
The document Trellis generates is named, in Danbury's own template, the Guaranteed Experiences Document.
- ·Every unit carries a Career-Connected Lens and a Real-World Connection that tie the learning to the pathway's industry, certifications and careers.
- ·Multilingual learners are served from the start: vocabulary cognates generate in Spanish and Portuguese, and the district's language scaffolds are carried automatically.
- ·Units are designed backward from a real end assessment, the way the strongest pathway teachers already build, so each experience leads to something students can show.
Danbury built this beside its own teachers, and can show a measured result. Other districts can have the same, fitted to their own frameworks.
The next build
Since the first build, Danbury has added grades 9 to 11 and signed on to keep Trellis running.
Deeper in Danbury
Planned next: the rest of the high school, then K-12 curriculum, carrying the same consistency and time savings into middle and elementary writing. This expansion is planned and still to be signed. The hardest part, codifying how Danbury builds, is already done.
Beyond Danbury
Every district writes curriculum its own way. Trellis is fitted to each one in person, beside its teachers, with Danbury's build as the first.
