Trellis turns a year of classroom visits into a growth story your teachers will want to read.
Great teacher feedback takes time you don’t have.
So most teachers never get it.
School admins know great feedback grows teachers better than anything else. But great feedback takes time.
There are scattered notes, voice memos from walkthroughs, artifacts from observations—and remembering every crucial detail from every classroom visit is impossible.
So end-of-year evaluations get compressed into generic admin-speak.
Teachers notice. Students notice.
The greatest opportunity for professional growth—coaching in the classroom—becomes a box-checking exercise that helps no one.
Students thrive when they have great teachers. Teachers thrive when they get great feedback.
Trellis helps you give it.

“The feedback captured what I actually do in the classroom. Trellis makes me feel seen and acknowledged.”

Everything you need to know about Trellis as a growth-first feedback platform.
No. Trellis is a professional growth platform, not an evaluation system.
It helps leaders capture and organize feedback from walkthroughs, coaching sessions, and classroom visits so feedback becomes faster, clearer, and more actionable. Trellis doesn't generate scores, ratings, or evaluation forms — it simply helps make good feedback easier.
Administrators decide what information to share with teachers — just like in any walkthrough or coaching process.
When feedback is shared, it's visible to the teacher and designed to start a professional conversation. Nothing in Trellis is automatically pushed into personnel files or formal evaluations.
Trellis makes feedback:
It's about learning, not compliance — creating more frequent, lower-stakes conversations around teaching.
Trellis helps leaders spend less time writing reports and more time in classrooms.
By organizing feedback across classrooms, it helps identify schoolwide trends and guide PD decisions — without singling out individual teachers.
No. Trellis is intentionally separate.
It's a coaching and growth tool, not an evaluation platform. Districts can use Trellis to complement their existing systems, but the data inside Trellis is meant to support professional learning, not personnel decisions.
Trellis was built by educators who understand that trust is everything.
Administrators control visibility, but the tool encourages openness, reflection, and clarity. Teachers always know when feedback has been shared — there are no surprises.
The spirit of Trellis is collaboration: helping good feedback happen more often, and making growth visible in supportive, transparent ways.
Trellis runs on Claude, made by Anthropic — the same AI family trusted by security-conscious enterprises — with OpenAI models as automatic backup.
The AI drafts; your leaders review, edit, and deliver everything. And teacher names are replaced with anonymous codes before any text reaches an AI provider. Read the full technology FAQ.
No. Trellis uses Anthropic and OpenAI through their commercial APIs, and under those terms customer data is not used to train their models.
On top of that, teacher names are swapped for anonymous codes before any text leaves Trellis.
Data is encrypted in transit and at rest, every record is scoped to your school's workspace on every query, and access is role-based.
Your admins can export the school's complete dataset anytime, and deletion is built into the product. Your data is never sold or used for advertising.
Trellis is designed to support your FERPA obligations, and we'll sign a data processing agreement that puts our responsibilities in writing.
Trellis holds staff observation and feedback data — there are no student accounts and no student records — and deletion rights are built into the product.
Yes. Trellis can align with your instructional framework, walkthrough forms, and focus areas. The platform is flexible so each district or school can shape how it's used — from pilot feedback cycles to full instructional coaching models.
Trellis aligns with union values: fairness, professionalism, and respect for teacher voice. It's non-evaluative, transparent about how data is used, and designed to reduce stress around feedback and evaluations — not increase it.
Because growth takes structure. Just like a trellis supports a plant's upward path, Trellis helps teachers and leaders grow together — organized, supported, and connected.
