| Selection and application | Selection: Each of six campuses accommodates roughly 160-200 students, and clusters typically enroll 20-25 with a commonly reported 5:1 student-to-faculty ratio. Admissions are competitive and based on academic merit relative to the selected topic, but applicant count and statewide acceptance rate were not published. Application materials: Online application with one personal statement; One teacher recommendation (two recommended) | Selection: Most paid camps use registration and capacity rather than a single competitive admissions process. Scholarship and partner-funded programs have separate eligibility and limited funds; the umbrella applicant count, seats, fill rates, scholarship rates, and selection criteria are not published. Application materials: One teacher or counselor recommendation for Camp Tiger scholarship consideration | Selection: Selectivity ranges from registration-based online courses to holistic selective residential programs and competitive paid research. WashU does not publish one umbrella application count, acceptance rate, capacity, waitlist, or rubric; each linked unit controls its process. Application materials: For selective Arts & Sciences programs: short essays, $50 fee or qualifying waiver, transcript, and one teacher recommendation; Separate local-residency, research, portfolio, financial, rural, or employment materials for other WashU programs |
