Why 'train and hope' never worked — and what actually changes practice.

In 2005, Dean Fixsen and colleagues at the National Implementation Research Network published the most comprehensive synthesis of implementation research ever undertaken — 250+ studies across health, education, mental health, and social services. Their conclusion challenged two decades of professional development orthodoxy: training by itself doesn't change what practitioners do. What changes practice is organizational infrastructure. This is what Trellis is built to provide.

Key Takeaways
The Problem
Despite advances in evidence-based programs, effective and consistent implementation in classroom settings remains a challenge.
The Findings
Training alone appears insufficient for effective implementation; without support, developed competencies rarely translate into consistent practice.
The Trellis Solution
Trellis is the organizational driver that makes training translate.
01

Training alone doesn't change what teachers do.

The central finding of Fixsen et al.'s (2005) synthesis is blunt and uncomfortable: professional development, in isolation, doesn't work. Not because training is poorly designed. Not because teachers aren't paying attention. But because the gap between learning something in a workshop and doing it automatically during instruction is not a knowledge gap — it's an infrastructure gap.

Fixsen reviewed the evidence from experimental studies across multiple fields: health, mental health, education, juvenile justice, social services. In every domain, the pattern was the same. When practitioners received training without accompanying organizational support, implementation rates hovered between 0 and 20%. When organizational support structures were in place, implementation rates approached 80–90%.

For education specifically — and for MTSS in particular — this means that the majority of districts are spending significant resources on training that, by the weight of the evidence, produces minimal lasting change in classroom behavior. The training is real. The investment is real. The failure is also real, and it's predictable.

"Training by itself seems to be an ineffective approach to implementation. The 'train and hope' approach does not appear to work."
Fixsen, Naoom, Blase, Friedman & Wallace · Implementation Research: A Synthesis of the Literature (2005)
Chapter 4 — Staff Training section · NIRN Monograph

The phrase "train and hope" — originally coined by Stokes and Baer in 1977 — describes the dominant model in professional development: provide training, assume transfer, discover failure, provide more training. Fixsen's synthesis found no evidence that this cycle produces different results with repetition. The model itself is the problem.

📊
Key Finding · Fixsen et al., 2005 · Chapter 4
"These experimental studies suggest that training by itself does not result in positive implementation outcomes — changes in practitioner behavior in the clinical setting — or in intervention outcomes — benefits to consumers."
T How Trellis addresses this
Trellis is not training. It is the organizational infrastructure that converts MTSS training into daily classroom practice. When a teacher marks a student Yellow on the assessment scale, the intervention trellis surfaces trained strategies automatically — no recall required. The gap between workshop knowledge and instructional action closes because the tool is present in the moment instruction happens.
02

Implementation requires three kinds of drivers.

Fixsen's most important contribution is not simply documenting that training fails — it's explaining what successful implementation actually requires. His framework identifies three categories of organizational drivers, each essential, none sufficient alone:

Competency Drivers build the skills of practitioners and their supervisors. They include staff selection (who you hire matters as much as how you train them), pre-service and in-service training, and coaching that bridges workshop knowledge and daily practice.

Organization Drivers change the structures, systems, and data flows that practitioners work within. They include systems interventions (tools and workflows that make new practices easier), facilitative administration (leadership that removes barriers rather than adds requirements), and decision support data (feedback mechanisms that make implementation visible).

Leadership Drivers sustain implementation over time through both technical leadership (solving known problems with known solutions) and adaptive leadership (navigating complex change with no clear playbook).

Fixsen et al. (2005) — Three Implementation Driver Types
Competency Drivers
  • Staff Selection
  • Pre-Service Training
  • In-Service Coaching
Districts invest heavily here
Organization Drivers
  • Systems Intervention
  • Facilitative Administration
  • Decision Support Data
← Trellis provides this
Leadership Drivers
  • Technical Leadership
  • Adaptive Leadership
Present but undersupported
Effective Program + All Three Drivers = Desirable Outcomes  ·  Effective Program + Training Only = Predictable Failure

Fixsen's framework reveals a critical misalignment in how most districts approach MTSS: they invest almost exclusively in competency drivers (training, coaching) while neglecting the organizational driver tier entirely. The result is exactly what the research predicts — capable teachers who know what to do but lack the systems infrastructure to do it consistently.

"Desirable outcomes are achieved only when effective programs are implemented well. Effective programs can be implemented poorly. This is not desirable."
Fixsen et al., 2005 · Chapter 3 — Conceptual Framework
03

The organizational driver is the missing piece in MTSS.

Of the three driver types, the organizational driver is the most consistently underfunded and least understood in educational contexts. Fixsen describes it as the infrastructure layer that makes trained behaviors feel natural and automatic rather than forced and effortful. He draws an instructive analogy from Toyota's production system:

Successful implementation requires the "massive reorganization of production units, visual control and communication by workers with other workers, and specific arrangements of plant operating and management structures to support production teams and a consistent flow of materials."
Fixsen et al., 2005 — Toyota Production System example · Chapter 3

Toyota didn't improve quality by training workers to care more about quality. They redesigned every workflow, every physical workspace, every communication channel so that the quality-producing behavior was the path of least resistance. The new way became easier than the old way.

For MTSS, the implication is direct: until the intervention-documenting behavior is easier than the alternative (not documenting), it will be inconsistently performed regardless of training quality. The 30-minute end-of-day logging that most MTSS systems require isn't just inconvenient — it structurally guarantees inconsistent implementation, because it competes with every other demand on a teacher's time and energy at the end of a school day.

T How Trellis addresses this
Trellis is the Toyota redesign for MTSS documentation. It makes the intervention-documenting behavior the path of least resistance by embedding it into a tool teachers already use — the seating chart — and reducing the time cost from 30+ minutes to under 5 seconds per student interaction. When the new behavior is faster and easier than the old behavior, implementation follows naturally.

Fixsen also identifies decision support data as an essential organizational driver: a regular flow of reliable information about performance, acted upon by practitioners, managers, and the organization. This feedback loop is what distinguishes organizations that improve from those that stagnate. Without visible data on implementation, there is no basis for coaching, no basis for celebration, and no basis for improvement.

🔄
Key Finding · Fixsen et al., 2005 — Feedback Mechanisms
"A regular flow of reliable information about performance of individuals, teams, and organizations acted upon by relevant practitioners, managers, and purveyors" is an essential implementation component. Without this feedback loop, improvement is impossible.
04

Coaching closes the gap — but it doesn't scale.

Fixsen's analysis of Joyce and Showers' coaching research (2002) provides the single most compelling data point in the entire implementation literature. When you measure the relationship between training type and implementation rates, the gap between coaching and no coaching is extraordinary:

📈
Joyce & Showers (2002) — Referenced in Fixsen et al., 2005
Training alone (theory + demonstration + practice): 0–5% transfer to classroom use.
Training + coaching: 80–90% transfer. The difference is not marginal — it is the difference between failure and success.

Coaching works because it provides what training cannot: feedback in real time, support in the actual performance context, and accountability across multiple instructional cycles rather than a single workshop experience. A coach can observe implementation, name what they see, suggest specific adjustments, and return to see whether those adjustments stuck.

The problem is simple arithmetic. A school with 40 teachers and one instructional coach cannot provide meaningful coaching across 40 classrooms with sufficient frequency to drive the 80–90% implementation rates the research identifies. The human bandwidth doesn't exist.

"The essence of implementation is behavior change. Training by itself seems to be an ineffective approach to implementation. However, it appears that the functional components of staff training are knowledge of the program and practices, demonstrations of key skills, and practice to criterion of key skills."
Fixsen et al., 2005 · Chapter 4 — Staff Training Summary
T How Trellis addresses this
Trellis doesn't replace human coaching — it scales the organizational functions that coaching provides. It observes what teachers are doing (intervention logs), provides feedback over time (personal analytics showing patterns), prompts strategy use in the moment (intervention trellis), and creates data artifacts that make coaching conversations specific rather than impressionistic. One coach with Trellis data can have substantively better conversations with 40 teachers than the same coach flying blind.
05

New practices must be easier than old practices.

One of Fixsen's most operationally useful insights is deceptively simple: for a new practice to replace an old one, it must be made easier — not just better or more evidence-based. Educators are not immune to the behavioral economics of cognitive load. When a new practice requires significantly more time or mental effort than the existing practice, the existing practice wins regardless of its relative ineffectiveness.

Fixsen identifies several common implementation barriers in school settings: difficulty securing release time for training, the compounding effects of absences and staff turnover on training participation, and the particular challenge of requiring teachers to demonstrate new skills in artificial "role play" settings rather than with real students in real instructional contexts.

Each of these barriers points to the same structural problem: most implementation efforts place the burden of change on the practitioner rather than redesigning the environment to make change easier. When burden falls on practitioners, those with the least available capacity — often those teaching the most challenging students — are the least likely to successfully implement new practices.

⚙️
Key Finding · Fixsen et al., 2005 — Barriers to Implementation
Common barriers in school implementation include: securing release time, absences and turnover degrading training cohesion, and role-play methods that don't transfer to real instructional settings. Effective implementation design removes these barriers rather than asking practitioners to overcome them individually.
T How Trellis addresses this
Trellis eliminates the three barriers Fixsen identifies: there's no release time required (teachers can be fully operational in one prep period), staff turnover has minimal impact (the seating chart interface is immediately familiar), and there is no role play — teachers practice with real students in real instructional contexts from day one. New teachers adopt quickly because the tool works the way classrooms actually work.
06

Fidelity monitoring requires continuous feedback — not annual observation.

Fixsen's analysis of successful large-scale implementation programs — including Multisystemic Therapy (MST) — reveals a consistent feature: they all have built-in feedback mechanisms that continuously monitor whether the practice is actually being used as intended. This is not the same as a principal observation or an annual program evaluation. It is ongoing, granular data about practitioner behavior in the actual performance environment.

"The MST Institute has a web-based system for collecting adherence data monthly at the practitioner and supervisory levels and using those data to inform decision making and consultation at the therapist and/or organizational levels. Adherence data are collected monthly for the life of each implementation."
Fixsen et al., 2005 · Chapter 3 — MST Example: Feedback Mechanisms

Notice what this describes: a digital system that captures what practitioners are actually doing, makes that data available to supervisors, and feeds it into ongoing consultation. This is not a once-a-year audit. It is a continuous loop that makes implementation visible at both the individual and organizational level.

For MTSS, the equivalent would be a system that captures what Tier 1 interventions teachers are actually using, with which students, and how often — automatically, without requiring separate self-reporting. This kind of data would allow instructional coaches to see implementation patterns without being physically present for every lesson. It would allow PLC teams to compare intervention effectiveness across classrooms. It would allow administrators to distinguish between high-fidelity and low-fidelity implementation before waiting for state assessment results.

T How Trellis addresses this
Trellis is the MTSS equivalent of the MST Institute's web-based adherence system. Every intervention is automatically timestamped and logged during instruction — no separate self-report required. Administrators see real-time Tier 1 fidelity dashboards. Coaches see intervention frequency and variety by teacher. PLCs see shared data on intervention effectiveness across classrooms. Fixsen's feedback mechanism exists, at the practitioner, supervisor, and organizational level, continuously — not annually.
07

Districts know teachers were trained. They don't know if teachers are teaching.

One of Fixsen's most pointed observations concerns the measurement problem at the heart of educational implementation. Districts have robust systems for tracking whether training occurred — sign-in sheets, PD hours, certification records — but almost no systems for measuring whether trained practices are being used in classrooms. The thing that gets measured is the easier thing to measure, not the thing that actually matters.

This creates a persistent blind spot. A district can demonstrate with confidence that 95% of its teachers attended MTSS professional development this year. It cannot demonstrate — with any comparable confidence — what percentage of those teachers are implementing MTSS Tier 1 strategies during daily instruction. The gap between these two numbers is the gap that Fixsen's research predicts, and that most districts have no way to observe, measure, or address.

🔍
Key Finding · Fixsen et al., 2005 — The Measurement Problem
Most implementation research measures program fidelity (was the program delivered as designed?) but rarely measures practitioner behavior change in real settings. Districts know teachers attended training. They don't know if teachers are using trained strategies in classrooms.
T How Trellis addresses this
Trellis makes practitioner behavior — actual teacher intervention use — visible and measurable for the first time at scale. This is not self-reported data or observation-based sampling. It is real-time documentation of actual practice: which interventions were used, with which students, in which periods, across which weeks. Districts move from measuring training attendance to measuring implementation fidelity, which is the measurement that actually predicts student outcomes.

Fixsen Finding What this means for MTSS Trellis Solution
Training alone produces 0–20% behavior change MTSS workshops don't change what teachers do in classrooms without organizational support Systems intervention — embeds MTSS into daily workflow automatically
"Train and hope" approach doesn't work Assuming teachers will implement after training, without support systems, predicts consistent failure Infrastructure replaces hope — documentation happens during instruction, not afterward
Organization drivers are essential and underfunded Systems interventions, facilitative admin, and decision support data are required — not optional Trellis provides all three organizational drivers simultaneously
Coaching + training = 80–90% implementation (Joyce & Showers) Human coaching works but doesn't scale across all teachers consistently Digital coaching functions — prompts, data, patterns — scale to 100% of teachers daily
New practices must be easier than old practices 30-minute end-of-day documentation structurally guarantees inconsistent MTSS implementation 5-second documentation during instruction — new behavior is faster than the old behavior
Strategies must be available at point of use Teachers can't recall 30+ intervention strategies under instructional load from memory Intervention trellis surfaces trained strategies automatically when a student needs support
Fidelity monitoring requires continuous feedback Annual observation and self-report don't create the feedback loop that improves implementation Real-time admin dashboard — Tier 1 fidelity data updated continuously, not annually
Decision support data must be acted upon at all levels Teachers, coaches, and administrators each need implementation data in forms they can act on Three-tier visibility: personal analytics (teachers), coaching reports (coaches), fidelity dashboard (admins)
Practitioner behavior change, not training attendance, is the outcome that matters Districts measure PD hours. They need to measure intervention use — what actually predicts student outcomes Intervention documentation creates the first real measure of MTSS Tier 1 implementation fidelity
