Many high school graduates today have had experience with smart phones, iPads and social media. Many university administrators have suggested that high school graduates already know everything about computers so there is no need for a university to offer an introductory computer course. University faculty who teach introductory computer courses know that many first year students have a very limited knowledge about computers. This paper will provide some data to establish what high school graduates know about computer concepts. This paper provides the results of 10 years of testing about computer concepts and shows that most students still know very little about computer concepts.
