TWI Trainer Development Certifications

What is Trainer Development?

A core component of Training Within Industry (TWI), the trainer development model is a framework for preparing employees to pass job skills and training methods on to others, who can then become trainers themselves. The process is designed to be iterative and scalable: initial instruction is delivered by a Master Trainer, after which trainees become certified and can transfer their coaching expertise on to others.

The Trainer Development model (train-the-trainer (TtT) style class), ensures that your organization stays agile and competitive in its field, able to attract and retain talent that prioritizes professional development and continuous improvement.

Become a Certified TWI Trainer

The TWI Institute Certified Trainer Program consists of separate 40-hour Train-the-Trainer (TtT) programs, one for each TWI program: Job Instruction (JI), Job Relations (JR), Job Methods (JM), Job Safety (JS), and Problem Solving (PS). The Institute also offers TtT Certifications for Kata and Toyota Kata. Participants can become a Certified Trainer for any or all of the programs.

All TWI Institute Certified Trainers become part of a community that provides:

  • Ongoing support and guidance though the Institute and Master Trainers
  • Training materials including participant guides, instructional cards and more
  • A blog with training and coaching insights from Master Trainers
  • Connections to TWI practitioners to compare experiences and share solutions in manufacturing, healthcare, construction and service industries

Participants are trained by experienced, engaging and committed Master Trainers using a consistent method proven by the documented successes of TWI Institute trainers around the globe. A Certificate of Completion will be issued to those who satisfactorily complete each 40-hour trainer program, having displayed a clear understanding of the Training Delivery Manual and all training materials.

Let’s Talk TtT

Why the TWI train-the-trainer method is effective

All trainers certified through the TWI Institute experience the successful TWI delivery methods developed during WWII and repeatedly proven throughout the years.
Learn-By-Doing Approach

Hearing and/or seeing is not enough. Learners practice their training delivery skills in a simulated course environment with hands-on practice.

Consistent Delivery

In this tightly defined program, all participants receive the exact same training delivered by Certified Master Trainers.


The one-week, 40-hour course format relays content in manageable segments, allowing participants to absorb material and accelerating learning and proficiency.

Scalable & Sustainable

Course delivery skills are standardized, so the processes will look the same throughout the entire organization.

Available Programs

Facilitated by a Certified Master Trainer, the 40-hour programs are standardized to ensure consistency of content, but flexible enough to foster a positive and supportive learning environment for each participant. Upon completion, participants will be able to confidently and skillfully deliver a 10-hour program on the topic.
