    Hi Justin,

    I just stumbled on your website today and have found it to be a hugely valuable resource. I live in the DC area and am in a situation that is similar to J’s, except that I am looking at master’s degrees rather than certificate programs. Like J., I also have a full-time job, so the options I am aware of would be either the relatively flexible part-time/evening MPS program offered at Maryland, or a 100% online program such as Penn State’s. Do you think there is an advantage to going either route in terms of job marketability? I’m not sure if an online master’s degree in GIS (without in-person classes or work experience) is a realistic way to start a career change, so I would appreciate your thoughts. Thank you!

      Hi Daniel,
      I prefer traditional programs to online. And I prefer MS or MA to MPS. My suggestion would be to take a single class to begin with, probably online, to see how much you learn and how it impacts your full-time job. Job marketability will have more to do with how you can translate your current/past experience as a valuable asset to complement GIS training. One other thought would be to explore the program at John’s Hopkins. I believe it’s fully online but sounds like it might be within reasonable driving distance to give you a bit of the best of both worlds.
      Hope this helps!
      Best wishes,
