middle school
wonder • maravilla

Smaller class sizes allow students access to engaging teachers determined to make each subject come to life. Our teachers abide by the philosophy of the artist Marc Chagall in “keeping awake the sense of wonder” for our students.


work • trabajo

We provide the instructional framework necessary for students to translate wonder into deeper practice. Wonder and curiosity meet consistent, hard work. Thomas Edison said, “There is no substitute for hard work.”


wisdom • sabiduría

Wonder and hard work lead to acquired wisdom. We partner with the University of Colorado-Denver to provide free college courses to juniors and seniors. Each UC-Denver course maintains ECA’s commitment to small and engaged class sizes.
