Step 3 Apply: applications are submitted online through Ravenna with no application fee; priority review is given to applications received by January 15; siblings of current students receive priority if their application is submitted by December 15; January 15 is the application deadline for priority review and the financial aid deadline. Step 4 Enroll: decisions are released by March 10; enrollment confirmations are due by April 10; ISB accepts applications year-round depending on space and student qualifications; applicants admitted after April 10 will have one week to respond to an offer of admission. Application materials vary by grade (Preschool & Kindergarten, Lower School, Middle School, Upper School) with language considerations and testing requirements as described.
Admissions
Step 1: Two diploma options are available: the International Baccalaureate Diploma (IB DP) and The Newman Diploma. The Newman Diploma mixes high-level and standard-level courses with requirements outside of coursework, including the extended essay and creativity, action and service. The IB pedagogy informs the curriculum, and students strive to embody the IB learner profile (inquirers, knowledgeable, thinkers, communicators, principled, open-minded, caring, risk-takers, balanced, reflective). Step 2: AP courses are not offered, but students may take AP exams alongside their IB work. All applicants must submit results from a standardized test; accepted options include the HSPT, ISEE, SSAT, PSAT, ACT, or SAT. Candidates whose primary language is not English may also submit English proficiency test results; the Duolingo English Test is preferred, though TOEFL and IELTS are also accepted. Step 3: Applications have two deadlines: Priority Applications due December 5, 2025; Standard Applications due January 31, 2026; Financial Aid Applications due January 15, 2026. Decision release dates are December 12, 2025 for Priority and March 10, 2026 for Standard and Financial Aid. To apply, click the Apply button at the bottom of any page; inquiries, visits, and applications are handled through the My Newman Ravenna hub (Inquire, Visit, Apply). Step 4: The Newman School has 260 students in grades 7–12/PG; 25–30 students in grades 7–8 and 45–60 students in grades 9–12/PG. Boarding is available; the school announced the purchase of 300 Newbury St. for a dormitory for the 2025–2026 year, with an anticipated 50–60 boarding students, offering both 5-day and 7-day options, and two dorms on Beacon Street with live-in dorm parents.
