Summary:
Portland, Connecticut, is served by a single public high school, Portland High School, which enrolls roughly 323 students across grades 9 through 12 under the Portland School District.
As the sole high school in the area, Portland High School has a significant impact on the community and has maintained an upper-middle-tier standing within the state. Over the past three years, it has consistently received a 3-star rating, ranking 58th out of 133 schools for the 2025–2026 school year. The school’s strongest subjects are English and Science, where proficiency rates of 57.7% and 56.3% outpace the state averages of 55.3% and 50.5%. The most pressing academic concern is mathematics, where only 32.4% of students are proficient, a rate far below its ELA performance. Additionally, ELA proficiency dropped sharply from 67.5% to 57.7% between the 2024–2025 and 2025–2026 school years, though the school still remains above the state average.
Beyond test scores, Portland High School posts a graduation rate of 90.2%, which is slightly below the Connecticut state average of 91.2% but above its own district’s rate of 89.2%. Chronic absenteeism stands at 15.7%, which is better than the state’s 16.4% but considerably higher than the Portland School District’s 11.1%, indicating some students may be at risk. Positively, the school maintains strong resources, including a low student-teacher ratio of 10.5 to 1 and per-student spending of $17,514. For parents, this means the school is well-equipped to provide individualized attention, yet the persistent math gap and slight graduation shortfall remain the key areas where improvement is needed to elevate its already solid statewide standing.
