USC welcomes applications from homeschooled students and evaluates them through a holistic review process. Homeschooled applicants are encouraged to provide detailed documentation of their curriculum, including course descriptions, reading lists, and assessment methods. Letters of recommendation should come from individuals who can objectively assess the applicant's academic abilities and readiness for college-level work. Standardized test scores, while optional, can provide additional context for the admissions committee. Demonstrating involvement in extracurricular activities, community service, or other engagements can also strengthen the application.

USC understands that admitted students may encounter unforeseen circumstances and offers the option to defer enrollment for up to one year. To request a deferral, admitted students must submit a formal written request outlining the reasons for deferral to the Office of Admission before the start of the term for which they were admitted. Each request is reviewed on a case-by-case basis, and approval is not guaranteed. Deferred students are typically asked not to enroll in another college or university during the deferral period and must submit a non-refundable enrollment deposit to secure their spot for the following year.
