Elementary Schools in Grafton

The Grafton school district in Massachusetts is home to four elementary schools: Millbury Street Elementary School, North Street Elementary School, South Grafton Elementary, and North Grafton Elementary. These schools serve students from kindergarten through 5th grade and are known for their strong academic performance.

Among the Grafton elementary schools, Millbury Street Elementary School stands out as the top performer. With a statewide ranking of 217th out of 906 Massachusetts elementary schools, Millbury Street boasts the highest proficiency rates on MCAS Next Generation assessments across all grades and subjects, significantly outpacing the other Grafton schools and the state averages. For example, in the 2024-2025 school year, 77.34% of Millbury Street students were proficient or better in Science, compared to 63.06% for Grafton and 41.51% statewide.

The other Grafton elementary schools also perform well above state averages on MCAS assessments, indicating the district as a whole is delivering strong academic outcomes. Additionally, the relatively low student-teacher ratios, ranging from 12:1 at Millbury Street to 13.6:1 at South Grafton Elementary, and high per-student spending, from $14,305 at North Street Elementary to $15,993 at South Grafton Elementary, likely contribute to the schools' success.
