Failure rates in introductory programming [PDF]
ACM SIGCSE Bulletin, 2007 It is a common conception that CS1 is a very difficult course and that failure rates are high. However, until now there has only been anecdotal evidence for this claim. This article reports on a survey among institutions around the world regarding failure rates in introductory programming courses.
