Common Ground High School District

Common Ground High School is the sole public charter high school serving grades 9-12 in the Common Ground High School District in Connecticut. With a total enrollment of 223 students, the school has a relatively low student-teacher ratio of 8.7 to 1, which could be beneficial for individual attention. However, the school faces some significant challenges, as evidenced by its fluctuating statewide ranking, academic performance gaps, and high chronic absenteeism rate.

Common Ground High School has a district rank of 122 out of 156 in Connecticut and is rated 1 star out of 5 by SchoolDigger. Its statewide ranking has varied over the years, ranging from 79 out of 121 high schools in 2017-2018 to 124 out of 200 in 2020-2021, with a current ranking of 87 out of 141 in 2024-2025. The school's test scores, particularly in Math and Science, lag significantly behind the state averages, with only 22.2% of 11th-grade students proficient or better in SAT Math and 30.2% proficient or better in Science (NGSS), compared to the state averages of 31.1% and 47.7%, respectively.

Additionally, the school has a relatively high chronic absenteeism rate of 17.7% for the 2023-2024 school year, which could be a contributing factor to the academic performance challenges. The school also serves a predominantly low-income student population, with 65.47% of students receiving free or reduced-price lunch. While the school's spending per student for the 2018-2019 school year was higher than the state average at $17,053, the data suggests that there may be opportunities for improvement in areas such as curriculum, instructional practices, student engagement, and targeted support for struggling students.
