Teachers aren't failing MTSS, MTSS is failing teachers
After 20 years of professional development, billions of dollars in MTSS investment, and thousands of hours of teacher training, less than 5% of learned strategies make it into daily classroom practice. The problem has never been teacher effort or expertise. It's the systems we gave them to work with.
Districts invest in training, but classrooms don't change
Every year, districts invest an average of $2,000+ per teacher annually in professional development. Yet research shows 80–90% of that training never gets implemented in classrooms (Fixsen et al., 2005). Trellis costs less than 5% of your PD budget but ensures the other 95% actually reaches students.
This failure is so consistent and predictable that researchers have a name for it: the "train and hope" approach. Train teachers in what to do. Hope they do it. Discover months later that they don't. Repeat the training. Hope again.
For decades, the field responded by blaming teachers, calling it a "motivation problem" or a "buy-in problem." But the research tells a different story. It's a systems problem, and no amount of training fixes a systems problem.
Why it fails
Training produces knowledge, but practice requires systems
Dean Fixsen and his colleagues at the National Implementation Research Network reviewed hundreds of experimental studies on training effectiveness. Their findings were clear: training by itself does not produce behavior change in applied settings. Not because the training is bad. Not because teachers aren't trying. But because training and implementation are fundamentally different problems.
Knowing what to do in a workshop and doing it automatically during instruction are separated by an enormous gap, which isn't closed by more training. It's closed by organizational infrastructure — tools, feedback loops, and systems that make the desired behavior easier than the old behavior.
Why it fails
The three reasons training doesn't transfer
01
Learned in training, but lost in the moment
MTSS training introduces 30–40 intervention strategies. In the middle of managing a classroom, teachers can recall approximately 3–5 under pressure. The rest disappear. Not from lack of interest, but because a human's working memory is decreased under instructional load.

02
The burden of documentation creates avoidance
When the expected post-instruction documentation takes 30–45 minutes, teachers make a rational choice: skip it, or do it so minimally it's useless. Every system that requires significant after-school time will be used inconsistently. That's not a character flaw, it's how humans respond to burden.

03
No feedback means no improvement
Without data showing which students received interventions, which strategies were tried, and whether they worked, teachers have no way to reflect on or improve their practice. Administrators have no way to coach. PLCs have no shared reality to discuss. The loop never closes.

The Trellis Solution
From train and hope to Train and Trellis
The training doesn't change. The research doesn't change. What does change is the infrastructure that connects training to daily practice — automatically, invisibly, and without adding a single task to a teacher's day.
Trained strategies are embedded in the tool and present at every instructional moment.
Customized interventions appear for each student for immediate support.
Documentation takes 5 seconds during instruction. Zero after-school work.
Every intervention is timestamped and visible to teachers, coaches, admins.
PLC meetings start with current, shared, classroom-level data.
Admins have real-time Tier 1 fidelity data across every classroom.
Coaches enter observations knowing exactly what teachers have been trying.
Backed by research
Three researchers over three decades One missing piece: infrastructure
Fixsen found that training fails without organizational systems. Wiliam found that formative assessment fails when it's burdensome rather than embedded. Zhou found that collective efficacy requires visible, documented mastery, not just belief. All three point to the same gap: the lack of daily infrastructure that makes evidence-based practice automatic. Trellis is built to fill that gap.
