Summary:
Zip code 06830 in Greenwich, Connecticut is home to four public elementary schools—North Street School, New Lebanon School, Hamilton Avenue School, and Julian Curtiss School—all serving grades PK–5 and part of the Greenwich School District, a top-ranked district rated 14th out of 153 in Connecticut, with a combined enrollment of 1,321 students.
North Street School is the clear academic leader, ranking 8th in the state (98th percentile) with the strongest test scores and the lowest chronic absenteeism at 7.3%. New Lebanon School is the most improved, jumping from 186th to 10th in the state in just two years despite having the highest poverty rate (61.6% free/reduced lunch) and the highest per-student spending. Julian Curtiss School is a consistent mid-upper performer at 73rd in the state, though its chronic absenteeism rate of 17% is double the district average. Hamilton Avenue School is the most challenged, ranking 161st, with the lowest test scores and the highest chronic absenteeism rate at 17.5%.
Several patterns stand out. Attendance strongly tracks rankings: the two top-10 schools have the lowest absenteeism rates, while the two lowest-ranked schools have rates above 17%. Spending does not perfectly predict outcomes—New Lebanon spends nearly double per student compared to Hamilton Avenue, while North Street achieves top scores with moderate spending. Smaller class sizes don't guarantee better results, as Hamilton Avenue has the lowest student-teacher ratio (7.9) yet the lowest scores. Upper-grade math is a common weak spot, with North Street and Julian Curtiss both seeing 5th grade math proficiency lag behind other grades, while New Lebanon's 5th grade math soared to 87.8%. All four schools beat state averages, but gaps within the district are large, making school choice particularly important for families in this area.
