For major requirements, students should thoroughly review the Bulletin. A broad overview of a HumBio course of study consists of the requirements listed below.

After the Human Biology Core, majors design their own Course of Study with a unique Area of Concentration topic. A Course of Study is made up of the Breadth, Depth and Upper Division requirements. Breadth & Depth courses can come from any department but should be consistent with the student's Area of Concentration topic. Additional requirements include Statistics and Capstone.

Declaration Process: Students are encouraged to start the declaration process in SFACT after successfully completing two of the core courses. Students are eligible to officially declare after successfully completing four of the core courses. See "How to Declare" to review the step-by-step process for declaring Human Biology.


Core:  The HumBio core is 30 units and sets the foundation for the rest of the major. 

Statistics: 3 units, must be on the list of approved Stats courses. Stats 60 is not approved. 

Upper Division:  any 3 HumBio courses numbered 100+, minimum 3 units each.


Area of Concentration: An area of Human Biology that is defined by the student and is made up of the Breadth and Depth requirements together.

Breadth: 20 units, courses must be related to your area of concentration. 10 flexible units are allowed which includes pre-requisites for Depth courses and/or pre-med units. Any course, including introductory courses and labs, related to your area of concentration except for Think, PWR, language and activity courses.

Depth: 5 or more upper-level courses with content that is directly related to the area of concentration with at least 3 departments represented and 20 units minimum.

Degree Option: HumBio offers two degree options, BA & BS. Majors take 10 or more units of the designated degree option within their Breadth courses and 5 or more courses in the Upper Division and Depth courses. For the 5 or more courses in the Depth & Upper Division, at least 3 of those courses must be in the Depth section. Courses are designated as BA or BS within SFACT. 


Capstone: Culminating Senior experience. Three options within HumBio include Practicum, Synthesis, and Honors. The Capstone requirement can also be fulfilled by Interdisciplinary Honors and other select programs. Students should identify their Capstone options during Junior year.


These are broad definitions of the degree requirement. For full details, students should review the Bulletin and discuss their academic plans with the advising team.
