Summary

Byam School is an elementary school in Chelmsford, Massachusetts, serving 530 students from kindergarten to 4th grade. The school consistently ranks among the top elementary schools in the state, with a current ranking of 246 out of 906 Massachusetts elementary schools.

Byam School's academic performance is particularly strong, with proficiency rates that significantly outpace the state averages in both English Language Arts and Mathematics on the MCAS Next Generation assessments. The school's spending per student is also higher than the state average, which may contribute to its success. However, there are some disparities in the performance of different student subgroups, with the school's Asian students and special education students performing relatively weaker compared to the overall student population.

When compared to nearby schools, Byam School's performance is generally stronger than other Chelmsford district schools, such as Center Elementary School and Charles D. Harrington. However, the Carlisle School, which is in a different district, outperforms Byam School across multiple academic measures, suggesting that there may be valuable practices or resources that Byam School could learn from.
