U.S. Presidential Scholars Program
Two recent Commonwealth alumni/ae, from the Classes of 2025 and 2022, progressed in the U.S. Presidential Scholars Program, recognizing exceptional high school seniors across the nation.
I was looking for somewhere I could be challenged and my interests in subjects like English and history could be deepened, which I definitely found at Commonwealth. Everyone here, both teachers and students, is passionate and curious, and it is very inspiring to be in that kind of environment.
