In many fields, graduate degrees offer distinct benefits for your extra years in school. Employees armed with a graduate education are often a more attractive hire, and can make a higher salary than colleagues who just have a bachelor's degree.

However, for some industries the potential benefits of going to graduate school are comparatively low, and potentially do not offer enough better job prospects to justify the investment.

Using this summer's "Hard Times" report from the Georgetown Center on Education and the Workforce, we examined salary and unemployment data relating to experienced college graduates and graduate degree holders.

We calculated the percent difference in how much more money a graduate degree will bring, as well as how much of a better chance you will have of finding a job. These figures were then combined to determine which graduate degrees are the most useless.

While the vast majority of graduate degrees will give you an edge, not all are created equal — and some graduate degree holders face a sharp rise in unemployment for their new job prospects.
