The Master of Public Health (MPH) degree is the most widely recognized professional credential for leadership in public health. The Harvard School of Public Health (HSPH) MPH program is designed for public health leaders, who aspire to high-level roles in state, federal, international health or the private sector. Five of the seven previous directors of the Center for Disease Control and Prevention, for example, received their MPH training at HSPH. Our students come from all parts of the world and often have relevant experience; over 90 percent have a prior doctoral degree. Many students are preparing for advancement in their organizations or transition into new fields.
