If your group is planning on running a user study, you will need to submit the IRB very early in the semester. For this assignment, you will write an IRB. To do this you will need to explore the documentation at the Carnegie Mellon University's IRB website.
NOTE: The normal IRB wait time is close to 4 weeks. Teri will arrange things around this schedule, but if you miss a deadline by even a day, she may shift you back into the normal queue.
