What students say...


"The Mod System offers 90-minute classes perfect for lab work. There are also opportunities to do off-campus work in classes like Marine Biology and Neotropics."
"Having hour and a half long classes is so nice! Before coming to CSW, I worried it would feel too long, but now I can't imagine ever going back to rushed 45-minute classes." 
"The biggest benefit of the Mod System is that it keeps school interesting. In my last school, the classes never changed. Eventually, all of the days seemed to blend together in one monotonous blur. At CSW, however, every day is exciting and I actually enjoy coming to school!"

"I love that instead of taking classes like '9th Grade History' or '10th Grade Science,' I can take 'World Religions,' or 'The Neurology of Teaching and Learning.'"
"For me, the biggest benefit of the Mod System is switching classes every six weeks. This allows us to meet and make friends with so many more people than we would otherwise. I think this is part of the reason why CSW is such a close-knit community."

What teachers say...


"In any given mod, I work with a much smaller number of students than teachers in a more traditional system—so I can get to know them really well, and give them truly meaningful feedback and more challenging assignments."


The Mod System at a Glance

  • The Academic Year is divided into six, six-week marking periods called Mods.
  • Each day consists of three 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 of instruction, students are awarded one credit. Three blocks of credit is equivalent to a full-year course in a traditional schedule.
  • 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, classes in performing arts, and extracurricular courses.
  • With over 250 courses to choose from, no two student schedules are alike.
