This calendar is intended to aid you with travel plans for the year ahead. Please pay close attention to departure times. We carefully plan and provide shuttle service so as not to conflict with school commitments. If you schedule your own transportation, please respect all school commitments for your child. Should airline travel require it, boarding students are permitted to remain on campus Friday evening of each of the school vacations. For information about the academic year, please visit our Academic Year Calendar page. Please call (413) 529-3266 or email deanofstudents@williston.com with any questions.
