P.S. 321 William Penn

Test scores here are in a different league than most Brooklyn schools — ELA at 88.7% and Math at 90.4% run roughly 25 points above the District 15 average. The school has recovered nicely from a dip during the pandemic years (2022 saw ELA drop to 78.7%), with consistent year-over-year gains pushing scores to their highest levels on record. Performance is strong across all tested grades, with Grade 4 math reaching an especially impressive 92.4%. Parents here are paying for results, and they're getting them.

The survey data reads like a dream scenario — 99% of teachers feel safe at work, 98% of parents trust the principal, and 96% of families are satisfied with the school. These numbers are exceptional even for a high-performing school. The school has maintained zero suspensions for three consecutive years, which combined with 95.6% attendance (above the district average) paints a picture of a community where kids are showing up and thriving. Family survey response rates of 70% (910 responses) suggest deep parental engagement rather than a handful of invested parents.

This is a predominantly white (70%) student body with higher economic stability than most NYC schools — only 6.7% economic need index compared to district averages. The diversity index of 58% is moderate, with 11% multiracial, 9% Asian, 7% Hispanic, and 3% Black students. The PTA raised over $1 million last year ($857 per student), which dwarfs the district average of $491 per student — families here have resources and they direct them toward the school. This is a community where parent involvement is the norm, not the exception.

Park Slope is one of New York's most family-oriented neighborhoods, with a 97% family density score and 82% of residents holding bachelor's degrees. The median home value of $1.6 million tells you everything about the economic profile here — this is a neighborhood where families have significant resources. Transit access is strong (79th percentile), though safety scores are moderate (37th percentile). The area is packed with parks, restaurants, and kid-friendly destinations, making it a magnet for families with young children.

Park Slope is highly walkable, and most zoned families arrive on foot. The neighborhood's grid layout and pedestrian-friendly streets make car-free mornings the norm for most households.
