Tuition that’s affordable

Graduate-credit tuition is about $2,200 per course. In total, tuition is between $22,000 and $27,000. After you are admitted, a variety of financial aid options may be available.

A Harvard credential

Youll earn a Harvard University degree: the Master of Liberal Arts in Extension Studies in the field of sustainability and environmental management with a concentration in ecosystems or sustainability.


To begin working toward your degree, start off with one 4-credit course. On your path to admission, you'll take three 4-credit program courses before submitting an application. This is a great way to find out if the program is the right fit for you.
