@jenjenjenjen - Connecticut College of Women was founded when Wesleyan stopped admitting women. It went coed in 1969. It has strong academics, and is known as one of the more artsy NESCAC schools. Vassar and Skidmore were also all female schools that went coed at about the same time. Wheaton College (in Norton, Mass) was another all female school that went coed in the 80’s.
We had a friend whose child was an accomplished performer in high school. He attended Conn College and liked it.
They have a relationship with the National Theatre Institute.
