International Product Training

We offer three distinct stand-alone courses endorsed by International. These courses provide training on two levels: generic coverage of fundamental truck knowledge, coupled with International product specific application exercises. TMI graduates know how to spec the best truck for any given application.

Students study each lesson in the course textbook and work through the ten tests and mail or fax them to TMI for grading. Grades and comments are often returned in one business day.

Unit 1

Medium-Duty Basics A great introduction for those new to truck, Unit 1 is a 10- lesson course that covers the basics of the CT-400 product data book and the MV and HV model lines. The cost for this in-depth medium truck product training is US$695 for USA and Canada.

Unit 2

Mid-Range Diesels Unit 2 provides advanced training, about 50 hours of study time is required for this ten lesson course using our 354 page textbook to provide full coverage of Class 5-6-7 diesels. The tuition is $795 per student.

Unit 3

Heavy trucks and tractors Our ten lesson International Unit 3 is highly recommended for all International sales personnel. Students study and are tested on International product information as well as advanced concepts in sales engineering and specing of Class 8 vehicles. Graduates complete ten written tests using the 392 page TMI textbook and your International product data. This in-depth course typically requires over 70 hours of study time to complete. The tuition is $825 per student.

GET THE eBOOK: The textbooks for Course III and Course IV are available as an enhanced PDF eBook on a CD in addition to the printed version. This is a $30 option for these courses. Using Adobe Acrobat Reader, students scroll through, read and search the textbook on most any computer.


Now is the time to consider this cost effective product training for your staff. Business sponsored enrollments are treated as company property. If an active course is not completed for any reason the value of the “unused” lessons can be credited to enroll another employee.
