Advanced Math and Science Academy Charter School (AMSA) is a charter school founded in 2005. It is located at 201 Forest Street in Marlborough, Massachusetts, U.S., in a few remodeled office buildings.
The school is widely recognized for its academic achievements, consistently scoring in the highest percentile among Massachusetts schools in the English, math and science MCAS exams. In 2018, U.S. News & World Report ranked the school the #2 high school in Massachusetts.As a charter public school, AMSA receives funding from the Commonwealth of Massachusetts. Students and their families have no direct costs other than uniforms and the fees for extra activities that have become common among most of Massachusetts' public schools.
Admission includes completing an application, attending an open house, and taking math and language arts tests that are solely used to determine placement in the right level of classes. Preference for the limited spaces is given first to siblings of current students regardless of residence, then to residents of Marlborough, Hudson, Clinton, and Maynard, and finally to any resident of Massachusetts.
The school is currently divided into a Lower School (grades 6-8) and an Upper School (grades 9-12) thus making a distinction between two parts of one continuous school.
