Sleepy Hollow High School, Sleepy Hollow NY

Original Research by School Decision on Sleepy Hollow High School

Sleepy Hollow High School serves students in grades nine through twelve in a town in Westchester County. The school is a regular public school within the Union Free School District of the Tarrytowns, which recently passed a major capital bond in December 2023 to fund four-story additions at its elementary schools and other facility upgrades. That bond carries defined property-tax increases for homeowners over several years, added to the district's annual operating budget increases.

The school's enrollment sits at around eight hundred students, with substantial diversity in student composition. More than half of the school's students qualify for free or reduced-price lunch. The enrollment is roughly split between Hispanic students, who make up the largest group, and white students, with smaller populations of students of color. Detailed data on English learners and students with disabilities were not available.

State testing data for this school were not captured in the current database. The school serves only grades nine through twelve, and New York's state assessments for which proficiency data are publicly reported focus on grades three through eight and high school Regents exams. Without those results, a parent cannot see how this school's students perform in core academic subjects relative to state standards or peer schools. This is an important gap to fill directly with the school or district, and a parent may want to ask about course completion rates, transcript patterns, college placement, and performance on Regents or other end-of-course exams that the school itself may track.

Relative to districts in Westchester County, the school's overall proficiency stands at the bottom quartile among the county's districts, though this comparison is limited by the absence of the school's own testing data in the state database. A four-year graduation rate was not available. Chronic absenteeism data were also not provided.

Housing in the Sleepy Hollow area is a mid-range market within Westchester County. Median home values are moderately elevated, and rents have ticked up slightly. The real estate market shows some cooling: active listings have grown, pending sales have dropped significantly, and the median time on market has shortened. Mortgage rates remain elevated, and rental costs consume a substantial share of household income relative to income-to-housing affordability benchmarks.

The district's bond project represents a visible commitment to elementary infrastructure, though it will reshape the financial reality for local homeowners through added property taxes over the next several years. For a family considering this high school, the immediate context is a school where academic outcomes are unclear from public state data, where enrollment is diverse and economically mixed, and where the district is undergoing active facility modernization at the lower grades. Direct conversation with the school about Regents exam performance, college readiness outcomes, and the nature of academic support available would help ground a family's decision.

Graduation rate (ACGR)

90-94%Cohort of 198 students · Class of 2021

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.

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.
