Delta Chi's values are best stated in the preamble to their constitution, which they use as a pseudo mission statement for the fraternity. This is the most public and perhaps the best known description of the purpose of Delta Chi. The preamble reads:

"We, the members of The Delta Chi Fraternity, believing that great advantages are to be derived from a brotherhood of college and university men, appreciating that close association may promote friendship, develop character, advance justice, and assist in the acquisition of a sound education, do ordain and establish this Constitution."

Delta Chi has four core values, which are mentioned in the preamble. The four core values of Delta Chi are: Friendship, Character, Justice and Education.

Eleven Basic Expectations of a Delta Chi
Delta Chi also has a collection of expectations for each member to uphold. These Eleven Basic Expectations serve as an extension of their Preamble and give them more specific principles to live by:
