What Is ITI?

The International Training Institute (ITI) is jointly sponsored by the Sheet Metal, Air, Rail, and Transportation International Association (SMART) and the Sheet Metal and Air Conditioning Contractors' National Association (SMACNA). ITI is the educational branch of the unionized sheet metal industry.

More than 15,000 apprentices are registered at training facilities in the United States and Canada. ITI supports apprenticeship and advanced career training for union workers in the sheet metal industry throughout the United States and Canada. ITI produces a standardized sheet metal curriculum supported by a wide variety of training materials free of charge to sheet metal apprentices and journeymen. These materials include:

The training programs and materials offered by ITI are the result of an employee welfare benefit plan established on May 12, 1971 to fund the training and development of apprentices and workers in the sheet metal industry. ITI commits to:


Our courses, textbooks, videos, and other learning materials are offered free of charge to trainees. Our combination of classroom learning plus paid on-the-job training offers an outstanding opportunity for trainees to earn while they learn.

Training Facilities

ITI has 153 training facilities throughout the United States and Canada. Our training facilities provide hands-on-training in state-of-the art labs. Training facilities are located in both urban and rural areas.


Our instructors are comprised of former or current sheet metal workers, managers or company owners. They provide a wealth of hands-on, real world experience. ITI's train-the-trainer program is designed to ensure a high standard of quality across the training facilities.

Our training centers are accredited by an independent acreditation board made up of members from Ivy Tech, SMACNA and SMART.

Flexible Learning

Our courses are available in a variety of formats designed to accommodate today's apprentices and journeypersons, as well as facilitate continuing education. Apprentices mostly attend classes and labs and may also take online courses for college credit. Journeypersons can continue education with specialized area certifications or make career path changes. Our learning formats include standard classroom and distance and online learning.

Student Profile

Our students work with a contractor while they attend classes. In fact, many remain with the same employer throughout their apprenticeship training. They receive a combination of classroom and on-the-job training that offers students an outstanding opportunity to advance in their careers while they learn. This combination ensures that the sheet metal industry has well-trained and educated workers.
