Best Elementary Schools in Zip Code 06480

Zip code 06480 in Portland, Connecticut, is served by two elementary schools—Gildersleeve School (grades 2–4, 253 students) and Valley View School (grades PK–1, 219 students)—which together form a split-grade elementary pathway for 472 students under the Portland School District, a district currently rated 3 stars and ranked 69th out of 153 districts statewide.

Both schools are well-supported and remarkably similar in resources: per-student spending is nearly identical at $15,341 for Gildersleeve and $15,242 for Valley View, and student-teacher ratios are close at 11.7 and 12.1, respectively. Attendance is a standout strength at both schools, with chronic absenteeism of just 4.5% at Gildersleeve and 4.0% at Valley View—roughly one-third of the district rate (11.1%) and one-quarter of the state rate (16.4%). The main demographic difference is economic need: Gildersleeve serves a higher proportion of economically disadvantaged students, with a 32.8% free/reduced lunch rate compared to 22.8% at Valley View.

Because Valley View covers PK–1, it has no standardized test scores, leaving Gildersleeve School as the clear academic anchor of the pairing. Gildersleeve earns a 4-star rating and holds a top-quarter rank among Connecticut elementary schools, landing in the 75th–85th percentile over the past three years. Current SBAC proficiency rates range from 64.5% to 72.5% in ELA and 70.0% to 71.0% in math—all well above state averages of roughly 47–52%—and these strong results come despite the school's higher poverty rate. That said, Gildersleeve's ranking has slipped modestly from the 85th percentile in 2023–2024 to the 75th percentile in 2025–2026, and year-to-year test scores have moved in mixed directions, suggesting cohort variability rather than a clear trend. For parents of the youngest students, Valley View's quality must be assessed through indirect indicators: excellent attendance, a lower-need student population, comparable spending, and small class sizes all point to a solid early-childhood foundation.
