What is ACHS?
From the ACHS website:
of College Honor Societies (ACHS), founded in 1925, is the nation's
only certifying agency for college and university honor societies.
ACHS sets standards for organizational excellence and for scholastic
eligibility for the various categories of membership: general, specialized,
leadership, freshman, and two-year honor societies. To assure member
participation in governance, honor societies must be structured
on a membership basis so that the interests of individual members
Members and society-at-large are protected by the
standards of excellence of the Association of College Honor Societies.
Not all organizations calling themselves "honor societies"
subscribe to the high honors' standards of ACHS. Candidates for
membership should assure that the honor society in question meets
the rigorous standards of ACHSboth the business model and
the scholastic eligibility criteria."
Omicron Delta Epsilon was admitted to ACHS in 1965.
