Is 340, Brooklyn NY - Test Scores & Data

Original Research by School Decision on Is 340

IS 340 is a regular public middle school in Brooklyn serving grades six through eight, located in a historically dense residential neighborhood with strong transit access. The school enrolls a small to mid-sized cohort for its grade band, with a student body that is majority Black and Hispanic. A substantial majority of students qualify for free or reduced-price lunch, reflecting the economic profile of the surrounding area.

State test results show proficiency well below the midpoint for middle schools across Kings County. In English language arts, the school reports proficiency rates that trend upward across the grade span, with the eighth-grade class notably stronger than sixth grade. In math, proficiency is lower and flatter, with less movement between grades. Eighth-grade science proficiency also lags. The school's overall proficiency index places it in the bottom quartile relative to other middle schools in the county. Student participation rates in testing are strong across all grades and subjects, suggesting consistent assessment administration. A parent evaluating this school on academic trajectory would want to look into the school's specific math and science interventions with staff, as those subject areas show particular room for growth. The reading mandate now in effect across all District 17 schools means all elementary feeder schools are using standardized literacy instruction, which may affect the foundational skills students bring to sixth grade.

The neighborhood around Sterling Place in Brooklyn blends dense residential blocks with active street life and frequent transit options. The broader borough of Brooklyn is highly walkable with substantial commercial corridors, parks, and cultural anchors; Prospect Park and the Brooklyn Public Library's branches serve as major civic institutions. Housing values have climbed steadily, and the rental market remains tight, consistent with broader Brooklyn trends of residential demand. The district itself is navigating a multi-year enrollment decline driven by residential population loss, a shift that has produced co-locations and re-sitings of schools as the city consolidates capacity. That backdrop of declining enrollment is a longer-term dynamic worth understanding when considering school stability and resource allocation in the district.

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.
