How this is scored→What stands out
- International studies curriculum anchored by Mandarin and Spanish language instruction
- Extraordinarily selective — just 5.9% of the 1,326 applicants received an offer last year
- 100% program richness score with rare offerings like Dragon Dance, Taiko Drumming, and Digital Photography
- Zero suspensions recorded — an unusual mark of a calm, well-managed environment
- 100% of teachers rated high on instruction quality, well above the district average
Things to consider
- Admissions are highly competitive — applicants need a strong application to have a realistic shot at one of 76 seats
- No subway access within walking distance means families need a reliable car, bus route, or commute plan
- PTA fundraising is unusually low at about $13 per student, far below the district average of $141 — the school likely runs lean on family-raised dollars
- Teacher survey participation was limited (26 respondents), so the staff-trust numbers carry a bit less weight than they'd appear to
- Class size matches the district average — families looking for unusually small classes won't find that advantage here
Based on 2025 data
School SummaryDistrict 31
District 31 covers Staten Island, and within this borough CSI High School stands out as one of the more academically focused, selective options for families. The peer schools listed are all elementary schools, so direct apples-to-apples comparisons aren't available, but CSI's 100% program-richness score and 100% teacher-instruction rating place it firmly at the top end of borough offerings. Where most Staten Island schools serve neighborhood enrollment, CSI draws from across the borough — sometimes the city — for its international studies focus.
Academics
Academic specifics worth highlighting: 100% of teachers are rated as high quality on instruction — a notable distinction among NYC schools and well above the district average of roughly 93%. The school offers AP courses, a humanities-heavy program, and dual world languages in Mandarin and Spanish, anchored by an international studies theme. Class size matches the district average of about 23 students, meaning kids aren't getting unusually small classes here. With no published ELA or math proficiency figures in this dataset, the strongest signal of academic quality is the curriculum depth (100/100 program richness score) and the unusually strong teacher instruction rating.
Culture
The climate here reads as unusually calm and trusting. Zero suspensions were recorded — well below the district rate of roughly 0.4% — and trust runs high across nearly every survey dimension: 95% of parents trust the principal, 93% trust teachers, and 100% of teachers rate their colleagues' instruction as strong. Teacher-principal and collegial trust sit at 88%, which is healthy though slightly behind the parent-side numbers. Worth flagging: only 26 teachers responded to the survey, which is a small sample, so the staff-side numbers are worth weighing with a grain of salt. Day-to-day, this looks like a school where adults cooperate, families feel heard, and discipline isn't a routine concern.
Community
The student body is more White than the typical NYC public school — 46% White, 23% Asian, 22% Hispanic, 7% Black — and that mix roughly mirrors the surrounding neighborhood, which is higher-income and homeowner-heavy. The school's diversity index of 74% places it solidly in the 'diverse but not highly mixed' range, with a clear majority-minority composition layered across multiple ethnic groups. About 18% of students have IEPs, and ELL support is part of the program, which signals the school serves a real range of learners even within its selective admissions frame.
Neighborhood
New Springville-Willowbrook-Bulls Head-Travis is a family-anchored, homeowner-heavy pocket of Staten Island. Median household income is about $98,000, the poverty rate sits at 10.5%, and 76% of homes are owner-occupied — well above NYC norms. About a quarter of households have kids, and 34% of adults hold a bachelor's degree or higher, which tracks with the college-prep feel of the school itself.
There are no subway stations within a 20-minute walk, so families here rely on cars, school buses, or local Staten Island public transit to get to campus. Plan the commute accordingly.
