Harvard Business School (HBS) offers primarily one core MBA program: the
Master of Business Administration (MBA). There are no specialized MBA tracks or concentrations within the core program; instead, the curriculum is designed to provide a broad foundation in business fundamentals, allowing students to specialize through electives and concentrations.
While HBS doesn't offer separate MBA *programs* like "MBA in Finance" or "MBA in Marketing," students can certainly focus their studies and careers in those areas through elective choices and recruiting. Therefore, while there's one main MBA program, the breadth of the curriculum allows for significant specialization.
