According to Niche 91% of freshmen live on campus, while according to Naviance, freshmen must live on campus, and I am having trouble finding answers on the website.
https://www.sarahlawrence.edu/media/student-life/pdf/student_handbook_16-17_8_26_16.pdf page 64 says that “First-year students and transfer students are required to live on campus during their first year at Sarah Lawrence.”
