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.

​​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.
