MPH Applied Practice Experience (APE)

All MPH candidates must complete an Applied Practice Experience (APE) as part of their graduation requirement. Most choose to do this through an approved summer internship between the first and second year of the program. Placements are usually 8-12 weeks in length and can take place at domestic or international locations.

In 2024, 79.6% satisfied the APE requirement through an internship. Those students were based in 72 cities in 19 countries around the world.

Internship sites that offered paid placements made up 42.7%, and the remaining students found funding from other sources (stipends, fellowships, etc.) to offset personal expenses.

Community

The Yale School of Public Health is known for its close community and collaborative environment. We maintain an ideal faculty-to-student ratio that provides students with many opportunities for mentoring relationships with leading public health experts and practitioners. Formal relationships are forged through academic advising, applied practice planning, and the thesis project. Close working relationships with faculty, as well as with classmates and alumni, form the foundation of a student's career network upon graduation.

Students are also deeply embedded into the fabric of the school’s mission through their work on funded faculty research and interventional work in public health. Many volunteer with student-run organizations such as the HAVEN Free Clinic and the Student Consulting Group, deepening their skills and ties to the greater community.
