The Problem Identified

Trellis Solution

Implementation Science

0–20% behavior change from training alone

No organizational infrastructure to support daily practice

Systems intervention + decision support data

Formative Assessment

2× learning speed with embedded assessment

Day-to-day assessment is rare because it's too burdensome

Five-second documentation during instruction

Collective Efficacy

d=1.57 — #1 influence on achievement

CTE formation not understood; mastery evidence not captured

Visible shared mastery + PLC data infrastructure
