Diesel Technology Program

Diesel Technology Program

This program is available at the Bellefontaine location. This program is taught in a modern, clean training facility at the Ohio Hi-Point Career Center at 2280 State Route 540 in Bellefontaine, Ohio. Some general education courses may need to be completed online or at our Springfield location.

The diesel industry is growing and there is a current and future need for qualified technicians. Diesel engines are more powerful and durable than gas engines, making them a popular alternative in the trucking, busing, agriculture, and construction industries. 

The Clark State Diesel Technology program is a comprehensive sequence of courses that combine theory and practical applications. Students learn theory, design, operation, diagnosis, repair and service of diesel engines, power train and chassis, hydraulic systems, and fuel injection systems. They develop communication and mathematical skills necessary for the diesel industry. The program includes 300 hours of on-the-job training in a co-op work experience.  Students also start earning industry credentials such as Detroit Diesel Engine Platforms, Freightliner Certifications, ASE Entry Level Certifications, and International Harvester Credentials.

Embedded Certificate
This degree program contains one or more embedded certificates which will automatically be awarded if the certificate requirements are met unless the student contacts Records and Registration and indicates he/she does not wish to have the certificate credential awarded. 

Career Information
