| Selection and application | Selection: MITES seeks strong, STEM-motivated students and prioritizes educational access in holistic review, but the current pages do not publish applications, cohort size or acceptance rate for 2027. Application materials: Three recommendations: a math or science teacher, a humanities teacher, and a school counselor or administrator | Selection: Admission considers academic readiness, completed materials, course prerequisites, age and format eligibility, and available space; Cornell publishes no minimum GPA or interview requirement. Course admission does not guarantee another institution will accept the credits. Application materials: Personal essay in English (1,000-1,500 words recommended, 2,000 maximum); One teacher or counselor recommendation | 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) |
