Graduate Degrees | Harvard Extension School

There are many options for an MA or MS degree online. Is there a reason he picked Harvard Extension? What area of study is he pursuing?

I believe- and someone can correct me if I am wrong- that the degree terminology serves to differentiate extension students from the other Harvard students. But I have heard the courses have good quality and professors enjoy teaching in the Extension school.

A typical 4 credit course is $3,440 which is more affordable than peer privates and comparable to publics, the site says. But it is a different degree, technically.

There is a requirement for some on campus participation (which varies).

Admission is dependent on doing well in a certain number of courses. Financial aid isn’t available until after admission based on finishing those courses well enough.

You have access to Harvard resources, including career services, library and so on.
