There plenty of people getting a BS from WGU that go on to Master level degrees at other universities. I know quite a few of them personally. Going to WGU for a BS and then a different university for a Masters, is quite possible and not unheard of.
This is actually what my sister did. She got a WGU Bachelors Degree and then went on to get a Master's Degree from a more recognizable college. She shaved 3-4 years off her full masters program that way (if you consider the time spent for the Bachelors degree in that process) and at the end of the day she is applying on her resume that she has a Master's from a recognizable university name that raises eye brows.
I am currently looking at doing the same.
If you do the math, it is possible to get a WGU Bachelors Degree + Full 2-Year Master's Degree program from a "recognizable" school for less money and in less time than most people are spending to get a bachelors degree from an unrecognizable community college.\
That's a life hack for anyone looking for Master's programs.
