Summary

Henderson K-12 Inclusion School Upper is an alternative public school located in Dorchester, MA that serves grades 2-12 with 639 students. As part of the Boston school district, which is ranked 298 out of 348 districts in Massachusetts and has a 1-star rating, the school faces significant challenges in serving its high-needs student population.

The school's performance on key metrics is concerning, with 4-year graduation rates ranging from 79.7% to 86.1% over the past few years, lower than the state average of around 90%. Dropout rates have also been higher, ranging from 2.8% to 9.5%, compared to the state average of 1-2%. On standardized tests, Henderson K-12 Inclusion School Upper significantly underperforms the state and Boston district averages, with only 13.78% of students proficient or better in math across all grades in 2024-2025, compared to 40.74% statewide and 27.68% in Boston.

When compared to nearby alternative schools, Henderson K-12 Inclusion School Upper performs worse on most metrics. For example, Horace Mann School for the Deaf and Hard of Hearing and Melvin H. King South End Academy have even lower test scores, while charter schools like Mystic Valley Regional, Pioneer Charter, and Brooke Charter significantly outperform Henderson on academics. The school's status as an "inclusion" school serving a high-needs population may be contributing to these challenges, despite spending around $28,000-$30,000 per student, which is higher than the state average.
