Schools in Zip Code 06831

ZIP code 06831 is home to two high-performing public elementary schools — Glenville School and Parkway School — both serving grades K-5 within the Greenwich School District, which ranks 14th out of 153 districts in Connecticut (91st percentile). There are no middle or high schools in this ZIP code, so families should plan ahead for secondary school options.

Parkway School is the clear standout in the area. It ranks 13th out of 491 elementary schools statewide (97th percentile) and has been in the top 5% for three consecutive years, climbing from rank 25 to rank 13. Its ELA proficiency is exceptional, with 91.7% of 3rd graders and 90.0% of 4th graders meeting state standards — well above district and state averages. Science proficiency is outstanding at 84.3%, far above the state's 52.9%. Chronic absenteeism is just 5.1%, and only 4.42% of students qualify for free/reduced lunch. If you are looking for a consistently elite elementary school, Parkway is the pick.

Glenville School is also strong but shows more variability. Its state rank slipped from 47th to 119th in 2025-2026, as proficiency dropped in nearly every subject compared to the prior year — including an 18-point decline in 5th-grade science (87.8% to 69.8%) and a 13.6-point drop in 3rd-grade math (80.3% to 66.7%). Both schools still far exceed state averages, but Glenville trails its own district averages by 5 to 19 points. One notable contrast is per-student spending: Parkway spends nearly double Glenville's amount ($25,624 vs. $13,446). Both schools have excellent attendance, well below the state's 16.4% chronic absenteeism rate. Overall, families in 06831 have two solid elementary options, with Parkway offering more consistent top-tier performance.
