English IV courses serve as semester-long electives, and Baylor students must take (and pass) two semesters of English IV in their senior year. Those courses that fulfil senior-level graduation requirements might vary slightly any given year, but typically include electives such as African American Literature, Literary Classics, Mystery and Murder in Literature, Literature of Medicine, Identity and Society in Literature, Modernism, Travel Literature, Wilderness Literature, and Women’s Literature.

Students may also elect to take specific Applied Humanities classes in order to meet general graduation credit requirements beyond those courses required for graduation.  Examples of Applied Humanities electives are Audio Journalism, Digital Narratives, Digital Texts and Research Methodology, and Film Production.

Fine Arts in the Upper School is comprised of tiers that depend on pre-requisite courses.  Students may take any year-long or any two semester-long courses in tier one to fulfill their graduation requirement. Beyond this, students may elect to take other courses such as  2D/3D Art & Design, Digital Design, Photography, Visual Literacy, Choreography & Dance, Drawing, Pottery, Form & Function, Painting, and Theater. Students may also choose to re-enroll in year-long Upper School courses in band, choir, and orchestra.

Students may choose to take History electives, typically beginning in their junior and/or senior year. While these courses fulfil general graduation credits beyond Baylor’s required courses, they do not qualify as required courses for graduation.  These electives might vary slightly any given year, but typically include year-long AP's like AP Art History, AP European History, AP Human Geography, as well as semester-long electives like African American History, American Government, Economics, Ethics, History of Christianity, Entrepreneurship, History of Global Affairs and Modern Contemporary Issues, History of the Middle East History of the Modern United States, History of Ethnicity and Ethnic Conflict, Global History of Women, Gender and Society, World Religions, and World War II in a Global Context.

Because Math classes are required all four years in the Upper School, students typically do not take math courses as electives. That said, students may elect to “double up” on math courses in certain years, but the second math course counts only to fulfil general graduation credits, not required math courses. While doing so does not qualify to fulfil a required course or general graduation credits, students may further enrich their experience in the math department by participating in the AMC 10/12 Contest, M3 Math Modelling Competition, and the Upper School Math Club.

In the Upper School, students may take Science electives, typically beginning in their junior and/or senior year. While these courses do qualify to fulfil general graduation credits beyond Baylor’s required courses (except in the case of AP Chemistry, AP Physics, and AP Biology courses), they do not qualify as required courses for graduation. Students may elect to take AP Environmental Science, AP Psychology, Anatomy and Physiology, Forensics, Marine and Aquatic Biology, Topics in Environmental Field Study, Robotics, Topics in Global Health.  Baylor Research includes beginning and advanced research electives (some semester courses and some year-long) in Engineering, Biomedical, and Environmental Science.

In the Upper School, Baylor students are required to take and pass two consecutive years of a World Language, after that, they may choose to continue taking language classes beyond their graduation requirement.  Some students elect to pursue classes in the same language every year until graduating, while others opt to begin studies in a different language.  Baylor students may choose from five languages: Chinese, French, German, Latin, and Spanish.
