At Penn College, we believe your educational experience should go beyond specialized skills. Real-world ready means taking a broader approach that builds communication skills, inspires collaboration, and encourages exploration of arts, history, and science.

​​Specialization requires in-depth knowledge and high-level proficiency. Students learn and apply major-specific concepts, skills, and methods.

  • Diesel Engine Technology (DSM154)
  • Diesel Engine Laboratory (DSM116)
  • Fuel Systems (DSM119)
  • Introduction to Hydraulics (DSM117)

​Perspectives are points of view, offering a variety of ways of understanding, interacting, and influencing the world. Students identify, explain, and utilize the approaches used by academics and professionals to study, analyze, or understand problems, and offer solutions.

​​Foundations are the practical, intellectual, and social skills: communication, collaboration, critical and ethical thinking, quantitative thinking, and technological literacy that are crucial to every student at every stage of education and at every stage of life.
