The New Trier Summer School program offers students experience in four areas: Academics, Enrichment, Sports, and Travel. Academic courses are offered during the regular school year, are considered introduction courses for specific department curriculum, and/or earn academic credit. Offered only during Summer School, Enrichment courses supplement the regular academic program and offer students the opportunity to upgrade present skills, pursue a new skill, or explore an area of interest. Incoming freshmen are only eligible to enroll in academic introduction courses, enrichment courses, and sports experiences and are not eligible to enroll in courses earning graduation credit.
