Summary:
Zip code 06413 contains just one public high school, The Morgan School, serving grades 9–12 in Clinton, Connecticut, with 473 students and a favorable 9.6:1 student–teacher ratio. Because this is the only high school in the area, the most useful comparison is against the Clinton School District and Connecticut state averages.
The Morgan School is a solid mid-to-upper-tier Connecticut high school, earning 3 stars and ranking in the 59th percentile statewide in 2025–2026. Its graduation rate of 97.5% is well above the state average of 91.2%, and students outperform Connecticut in both English language arts and science. On the 11th-grade SAT, 60.6% met proficiency in ELA versus 55.3% statewide, while 56.3% were proficient in NGSS Science versus 50.5% statewide. Math is the clear weak spot: only 30.5% of students were proficient on the SAT math section in 2024–2025, slightly below the state's 31.1% and dramatically lower than the school's own ELA and science scores. Roughly 4 in 10 students qualify for free or reduced lunch, making these above-average results particularly meaningful.
One growing concern is chronic absenteeism, which sits at 18.1% — well above the district's 11.9% and the state's 16.4%. This is especially striking given the school's high graduation rate and strong performance in most subjects. There are also early signs of a downward trend: ELA proficiency fell from 68% to 60.6% year over year, science dipped from 59.7% to 56.3%, and the school's statewide percentile slipped from 65 to 59. Even so, The Morgan School outperforms its district's 2-star rating, making it a relative academic strength in the Clinton community and a school with strong overall outcomes despite targeted areas for improvement.
