Did You Know?

The percentage of faculty with advanced degrees only indicates the percentage of teachers at a school with a degree beyond an undergraduate education.
It does not account for the type of degree received (e.g., PhD or Masters), the subject it was taken for, or what institution awarded the degree.
As only one variable in many for determining faculty quality, it should not be used in and of itself to assess whether one school's faculty and teaching approach is more appropriate for you than another school's.
