What is a degree emphasis? Is it the same as a concentration?
While an emphasis and concentration are similar, there are key differences.
- A concentration is a formalized selection of courses within a major requiring a minimum of 15 credit hours; at least nine must be upper division. The concentration appears on your ASU diploma and transcripts.
- An emphasis is a selected topic area defined within the major that’s typically 9–12 credit hours and doesn’t need to be officially declared.
