This paper reports on an investigation into the sophomore and senior preservice teachers' computer literacy in different teacher training programs and to determine relationship between grades and the teacher training programs in terms of their computer literacy. The study used case study research methodology, and the sample consisted of 276 preservice teachers. The "Computer Literacy Scale" comprising 24 likert-type questions was employed. The inferential statistical tests were used to analyze obtained data for comparing groups on the scores collected in multiple subtests. The results suggest that there was no difference between sophomore and senior preservice teachers' computer literacy. For computer literacy, the order of rank is basic skills, application software skills, computer awareness and programming skills, respectively. Undergraduate programs only have developed basic skills of preservice students and have not had the impact on other skills or sophisticated computer literacy. The MANOVA inferential statistics findings proved these results. It is suggested that content of the computer literacy skills and computer course(s) should be improved and re-designed by including computer literacy skills.
