I'm currently enrolled in two of Straighterline's courses.
Many people have easily transferred their credits to the colleges and universities that have specifically partnered with Straighterline, such as Excelsior, Thomas Edison, Charter Oak, Capella, DeVry, Colorado State's global campus, Fort Hays, etc.
Problems may or may not arise if you attempt to transfer the credits into a school that is not a partner college of Straighterline. If you are trying to do this, I would have your Straighterline courses transcribed onto an ACE transcript and see what happens.
One of the partner schools
, Fort Hays State Univ, will transcript five of Straighterline's courses as their very own: College Algebra, Macroeconomics, Microeconomics, Accounting I, and Accounting II. It appears as if you took the courses at Fort Hays, which makes it easier when trying to transfer credit into schools that are not involved in the Straighterline partnership.
