Diesel Technology is definitely high tech and in demand! It helps drive the Texas economy. Just take a look at the eighteen wheelers crowding the highways (they're carrying wind turbine parts and oil rigs to West Texas), the trains, the tractors, and even all the diesel-powered boats, and you'll see the power of diesel technology.

Through the training in the Texas State Technical College West Texas Diesel Technology Program, you'll learn all about diesel systems. That kind of training has enabled our graduates to choose careers in truck transportation, construction, the oil fields, and agriculture--everywhere diesel engines are used.

While in the Diesel Technology Program here at TSTC West Texas you'll get the chance to work with faculty with years of industry experience on a wide variety of equipment in our spacious labs on the Sweetwater Campus--plus, we'll help you learn the high-tech computer and electronics skills you'll need on the job. And during your final semester, if you choose to get your associate's degree, you'll have the opportunity to learn on-the-job (while getting paid and earning college credit) with one of many companies like Caterpillar, John Deere, or Cummins or at truck dealerships like Volvo, International, Peterbilt, or Freightliner.

  • Diesel-powered equipment
