Best Middle Schools in Zip Code 06480

Zip code 06480 (Portland, CT) is served by two public middle schools — Brownstone Intermediate School (grades 5–6) and Portland Middle School (grades 7–8) — both part of the Portland School District, which ranks 69th out of 153 Connecticut districts. Together, these two schools form the complete middle-grade pathway for Portland students, and both consistently outperform state averages across nearly every subject and grade level tested.

Portland Middle School is the higher-ranked school, earning 4 stars and ranking 62nd out of 258 Connecticut middle schools in 2025–2026. Its 7th-grade results are especially impressive: 79.8% proficiency in ELA and 62.6% in math, both far above state averages. It also showed dramatic year-over-year improvement in 7th grade, with ELA jumping 14.4 points and math 14.5 points. Brownstone Intermediate School excels in its own right, particularly with 6th-grade scores of 72.7% in ELA and 67.7% in math, and it maintains a very low chronic absenteeism rate of 9.2% — well below the district and state averages. While Brownstone does not have a listed school-level ranking, its academic performance is clearly above state norms across all tested grades.

The two schools show a stark contrast in attendance and resources. Portland Middle School has a chronic absenteeism rate of 16.9% — nearly double Brownstone’s — and a higher free/reduced-price lunch eligibility rate (32.7% vs. 25.8%). Its weakest area is 8th-grade math at 42.6% proficiency, barely above the state average. Interestingly, Portland Middle spends less per student ($15,708) but has smaller class sizes (11.0 student-teacher ratio) than Brownstone ($17,647 and 12.4). The transition between schools may also be uneven: Brownstone’s 6th-grade math proficiency (67.7%) is far higher than Portland Middle’s 8th-grade math (42.6%), though these are different cohorts. Overall, both schools offer strong, above-average education, with the biggest opportunities being reducing absenteeism at Portland Middle and strengthening 8th-grade math.
