During the week before the second semester students are required to participate in Intersession, a week they choose from among dozens of enrichment sessions and off-campus trips. Most students choose to participate in two half-day or one full-day on-campus course(s), while a relatively small number travel abroad on faculty-sponsored trips to countries including France, Spain, and Russia, and others perform a week of mentorship. Classes range from “Build Your Own Computer” to studying lighthouse keeping at Washington State. Alumni often teach Intersession courses and lead overseas trips along with faculty members. Clubs are also allowed to take trips and do activities during this time. The scuba club takes a trip to the Caribbean, while the FIRST Robotics team 2022 spends the entire week building the current robot.
