The Middle School program offers courses intended to develop not only content knowledge but also critical, creative, and abstract thinking skills.

In addition, the Middle School at Williams guides students to become respectful, responsible, and reflective students and citizens. Students are encouraged to take risks as they explore new ideas and connections and are empowered to take charge of their learning. By exposing students to a wide range of courses in the Middle School, Williams places an emphasis on the development of writing skills, analytic skills, and effective communication.

In grade seven, students take English, American History, Math, Life Science, Modern Language, and Enrichment. In grade eight, students take English, Geography, Math, Modern Language, Physical Science, Latin I, and Enrichment. Students are placed in the appropriate level of Math and Modern Language based on a placement test, previous coursework, and teacher recommendation. Enrichment offerings include Art, Music, Drama, Dance, Ethics and Service, Health, and Study Skills. Whenever students are not scheduled in a class, they are in a structured study hall. Band and Chorus are available as elective courses for students in grades seven and eight. Students in the eighth grade who participate in Band will postpone their study of either Modern Language or Latin until the ninth grade.
