The Module System

The Module System, also known as the Mod Plan, has been the cornerstone of our distinctive academic approach since 1973. The Mod Plan has always been innovative and continues to evolve in dynamic ways to meet the needs of our students and their education. The module plan offers students the opportunity to take an active part in shaping their educational experience, to experience broadly, and to learn deeply.

Our academic year is divided up into six modules (mods, for short), each lasting six weeks. During each mod, students take three blocks of academic classes that meet every day, usually for  90 minutes. These classes take place during A, B, and C-blocks. To meet our graduation requirements, students take challenging courses in the arts, English, language, history, math, and science. Many of our over 300 courses are offered as single blocks throughout the year, allowing for incredible depth into a specific theme or subject area. Subjects that call for sequential, cumulative learning, such as math or languages, are taught in blocks that span consecutive mods.

Students are also required to take a fourth block, known as D-block, during which they take part in athletics, physical education, community service projects, performing arts, and an array of other electives.

The module system works because of its versatility. With more than 300 courses to choose from, students have countless ways to structure their studies to suit their interests, while taking the foundational courses necessary to prepare for college and beyond. It works because it means taking fewer classes at a time, for longer time periods a day, allowing students to delve deeply into their material through experiential learning. The daily schedule is carefully crafted so that students have time for classes, assemblies, meetings with advisors, extra help, or clubs and activities—as well as some breathing time to recharge and relax.

The Mod System at a Glance

  • The Academic Year is divided into six, six-week modules
  • Each day consists of three 75- or 90-minute Blocks
  • Most courses are taught in a single block, but a few are taught in double, back-to-back blocks. For each block instruction, students are awarded one credit. Three to four blocks of credit generally equal a full-year course in a traditional semester system.
  • Some courses, particularly those in Math and Languages, span consecutive mods
  • At the end of the school day, D Block balances the three core academic blocks it follows. In addition to athletics, D Block choices include productions and classes in performing arts; advancement labs and academic support; and extracurricular courses.
  • With roughly 300 courses to choose from, no two student schedules are alike.

PACE: Promoting Awareness and Community Engagement

Every other Wednesday we utilize a modified schedule to accommodate our PACE (Promoting Awareness and Community Engagement) co-curriculum. The PACE co-curriculum develops skills and values central to CSW in a grade-based and developmentally appropriate manner. This is accomplished through collaborative learning, exploration, and reflection.Skills and topics include: identity and multiculturalism; equity and social justice; academic, social, and emotional skills; health, wellness, and mindfulness; engaged, responsible citizenship; leadership; and life skills and preparation for college life.
