Summary

Elmer Thienes-Mary Hall Elementary School is a public elementary school serving grades PK-6 in Marlborough, Connecticut, part of the Marlborough School District, which is ranked 49 out of 156 districts in the state. With 445 students, the school has consistently been ranked in the top 25% of Connecticut elementary schools over the past decade, currently ranking 120 out of 493 schools with a 4-star rating.

Elmer Thienes-Mary Hall Elementary School stands out for its strong academic performance, consistently outperforming the state average in standardized test scores across all grade levels and subjects. In 2024-2025, the school had significantly higher proficiency rates than the state in both English Language Arts and Math. The school also has a relatively low student-teacher ratio, ranging from 11.5 to 12.4 over the past three years, which is lower than many of the nearby schools like Nayaug Elementary School and Jack Jackter Intermediate School.

While the school performs exceptionally well for female and male students, its performance for white students is relatively lower, indicating a potential need to address achievement gaps among different student subgroups. Additionally, the school's high spending per student, at $16,414 in 2018-2019 and $15,090 in 2017-2018, may be a contributing factor to its strong academic outcomes, outperforming many of the nearby schools in the Glastonbury School District, Colchester School District, Hebron School District, and East Hampton School District.
