2023-24 Matriculation
The MPH degree requires a total of 20 course units. The MPH in Environmental Health Sciences (EHS) requires the student to complete or acquire an exemption from the following courses. Full time students must carry a minimum of 4 course units each semester. If a course is waived, a substitute course must be identified. In addition, all 2-year MPH students are required to complete an internship and an Applied Practice Experience (APE). An internship may fulfill both requirements if it meets certain conditions. Please refer to the Internship and Practicum Guidelines for more information.
