The initial design and initiation of StuCo was done by Ian Nieves (student), Janet Stocks (faculty), and Mark Stehlik (faculty), starting in 2001. The initial model for StuCo was based loosely on Oberlin College's own ExCo (Experimental College) program for students. However, StuCo's rigorous application process helps ensure that all StuCo courses are taught at a reasonably high level of quality, thus making the application process highly competitive. This was necessary in order for StuCo to be able to grant credit for the work of the course teachers and course students, and also helps keep StuCo courses fun and intense, like many other traditional CMU courses.
