The top reported proficiency rate is 49% in English language arts. The lowest is 42% in Science.
Original Research by School Decision on Advanced Math and Science Academy Charter (district)
The Advanced Math and Science Academy Charter School, known as AMSA, is a single-school charter district serving grades six through twelve in central Massachusetts. It draws students from several towns but maintains a formal charter focus on Marlborough, Hudson, Maynard, and Clinton, with admission by lottery. The district’s enrollment is spread fairly evenly across middle and high school grades, which gives it a stable, secondary-sized student body rather than the typical elementary-to-secondary K through twelve model.
Academically, AMSA’s state test results place its overall proficiency across the subjects it tests below the midpoint when compared with other districts in Middlesex County. In math and English language arts at the middle school level, proficiency rates are moderate, and science results follow a similar pattern. The eighth-grade social studies assessment, which is taken by only that grade, also lands in a comparable range. These are not standout scores for a county that includes many high-performing districts, but they represent a solid academic floor for a school that draws a lottery-based population. Chronic absenteeism, however, is notably low, sitting in the top quarter among county districts, which suggests consistent student attendance and engagement.
The student body is majority white, with Asian and Hispanic students each making up roughly a tenth of the population and Black and multiracial students comprising smaller shares. A very small number of Native American and Native Hawaiian or Pacific Islander students are also enrolled. Data on students who qualify for free or reduced-price meals, who receive special education services, or who are English learners were not available in the data provided; families looking at AMSA may want to ask the school directly about its support structures and the socioeconomic and learning diversity of its student population. Graduation rate information was also absent, so it is unclear whether the high school outcomes match the rest of the academic picture.
A significant recent change directly affects families from Marlborough, one of AMSA’s core towns. A state-imposed Net School Spending cap has sharply limited the number of Marlborough residents who can be admitted through the lottery. For the most recent lottery cycle, offers were restricted to siblings of current students and to only a small number of non-sibling Marlborough applicants. The vast majority of Marlborough residents who applied were placed on the waitlist and were not eligible to enroll at all. This cap is ongoing, so any Marlborough family considering AMSA now faces much lower odds of admission than in prior years, and the lottery process no longer functions as an open draw for local residents. Families from the other core towns may not face the same restriction, but the overall admission environment has tightened.
Per-pupil spending at AMSA is in the lower range among Middlesex County districts, which is typical for a charter school that operates on a per-pupil allocation from the state rather than local property tax revenue. This leaner spending profile can sometimes mean fewer elective offerings or extracurricular resources, though without detailed course access data it is hard to say exactly how it plays out day to day.
AMSA offers a clear academic pathway from middle school through high school under one roof, with a math and science emphasis embedded in its name and curriculum. The school’s consistent attendance and stable enrollment point to a structured environment. For a family weighing whether to apply, the biggest practical consideration is the new admissions cap for Marlborough residents, which has fundamentally changed who can realistically hope to gain a seat. Outside of that constraint, the school presents a moderate academic profile within a competitive county, without the top-tier test results of some nearby districts but also without the attendance problems that plague others.
