Csi High School for International Studies, Staten Island NY

Original Research by School Decision on Csi High School for International Studies

CSI High School for International Studies is a mid-sized public high school serving grades nine through twelve on Staten Island's North Shore. It draws a student body that is economically mixed and racially diverse: roughly three-fifths of students qualify for free or reduced-price lunch, and the enrollment reflects a fairly even distribution across Asian, White, and Hispanic student populations, with smaller numbers of Black and multiracial students.

The school's enrollment is stable across grade levels, with a comparable number of ninth graders through twelfth graders. Data on state assessment results, four-year graduation rates, and chronic absenteeism were not available, so a parent looking for academic performance measures and completion outcomes should request those directly from the school or district. The school does not report counts for students with individualized education plans or English learners, which often means those data are either collected separately or the gaps reflect how the school reports to the state. Given the school's title and mission focus on international studies, understanding what that pathway entails, what language offerings exist, and what dual-credit or post-secondary partnerships the school maintains would be worth asking about.

CSI sits within New York City Geographic District 31, which covers all of Staten Island. The district faces a significant shortage of elementary school seats, though this particular high school is not directly affected by elementary capacity problems. The broader housing and community context on Staten Island is residential and suburban. Home values in the school's zip code are moderately above the statewide median, and rents have been rising, though the island retains a more affordable and spacious feel than other parts of the city. The neighborhood character is mixed: parts of the North Shore where this school is located blend older residential streets with waterfront development, retail corridors, and maritime industry, while much of Staten Island remains leafy and car-dependent rather than densely urban. The borough has extensive parks and library branches, a free ferry to Lower Manhattan, and the Staten Island Railway, though transit is less continuous than in other boroughs.

Employment on Staten Island centers on healthcare, retail, and some maritime work. The economy is stable but not booming. Population growth has been modest, and housing development is constrained by zoning and infrastructure, though new waterfront projects on the North Shore are bringing more affordable units and mixed-income communities. For a family considering CSI, the school's appeal may hinge on its international focus and the peer group it attracts. Whether the school's curriculum, extracurricular offerings, and academic culture align with a student's interests would be the next place to look.

Graduation rate (ACGR)

The federal source publishes a banded range instead of an exact rate when the graduating cohort is small enough that an exact number could risk identifying individual students.

How this school compares to all schools in this state

Each dot is one school’s SY 2020-21 graduation rate, binned by integer rate. Taller columns mean more schools at that rate. This school is highlighted.

Graduation rate (ACGR) reflects the federally published Adjusted Cohort Graduation Rate for the most recent year available. We refresh this data annually at the close of each academic year in June. The federal source publishes a banded rate (for example, "90-94%") instead of an exact number for cohorts small enough to risk identifying individual students. The state distribution chart, where shown, plots every school in the state with a published rate or band; schools whose rate is federally suppressed are excluded. Where the federal source publishes a band rather than an exact rate, the school is placed within its band using a stable, ID-derived offset, so its position is consistent across visits.
