Elementary Schools in Groton-Dunstable

Summary:

The Groton-Dunstable school district in Massachusetts is home to three elementary schools: Florence Roche School, Swallow/Union School, and Boutwell School. These schools serve students from pre-K through 6th grade in the Groton-Dunstable community.

Among the three schools, Swallow/Union School stands out as the top performer. It has consistently ranked among the top 25 elementary schools in Massachusetts over the past three years, with a current ranking of 109 out of 906 schools. Swallow/Union School has also received a 5-star rating from SchoolDigger for the past two school years, indicating it is one of the highest-performing schools in the state. The school's MCAS proficiency rates in both English Language Arts and Mathematics are significantly higher than the district and state averages across all grade levels.

While Florence Roche School is also a strong performer, its rankings and test scores are not quite at the same level as Swallow/Union. Boutwell School, being a pre-K only school, has limited data available for comparison. However, the higher per-student spending at Boutwell School does not necessarily translate to higher academic performance, as the student-teacher ratios are relatively consistent across the three schools.
