Every other documentation system asks teachers to remember what happened and write it down later. Trellis captures it in the moment — during instruction, without interrupting it. Five seconds. Complete record. Lesson over.
The Documentation Problem
The problem was never that teachers didn't care. It was that every documentation system was designed for after the lesson — when the moment had already passed.
How It Works During a Lesson
This is what happens every time you interact with a student during instruction. Every single step. Start to finish.
Each interaction in Trellis isn't a note — it's a structured data point. When you save, Trellis records the student, the date and time, the performance level, the specific competency you observed, the intervention you used, and any notes you added. All of it is immediately searchable and reviewable in the History tab.
The history tab shows the full record for that student — every interaction ever logged, in chronological order. Color changes, behavior patterns, and intervention frequency all become visible over time.
Most documentation systems treat teacher time after the lesson as free. It isn't. The average teacher with four to six classes per day who faithfully documents MTSS interventions post-lesson spends 20–45 additional minutes per class. That's up to four hours added to a teaching day that's already full. Trellis doesn't add those hours because the documentation happens during instructional interactions that were already happening.
Dylan Wiliam found that genuine daily formative assessment documentation required 20–45 additional minutes per class. Trellis makes that 5 seconds. That's the difference between "train and hope" and practice that actually sticks.
What Builds Over Time
Individual 5-second interactions are useful in the moment. But the record they build together is what changes how teachers see their students — and how schools see their classrooms.
When students are working in groups, Trellis lets you document at the group level without losing individual records. Tap a group name in the Groups view and the participation window applies to all students in that group simultaneously. One color, one intervention, one tap — and every student in the group has a timestamped record.
Data You Can Trust
Post-lesson recall introduces errors that compound over time. Trellis data is captured at the point of interaction — making it qualitatively more accurate than anything written hours later.
