The purpose of this study was to define the self-efficacy perception of Turkish ELT students and examine the relationship between their self-efficacy and such variables as grade level, computer ownership, first time computer use, and frequency of internet and computer use. The participants are 305 Turkish ELT trainees at Dokuz Eylul University, Turkey. To collect the data, arithmetical means, standard deviation, variance of analysis, and Scheffe test were utilized. The majority of prospective Turkish teachers of English demonstrate a moderate level of computer self-efficacy. It was also found that computer-related self-efficacy perception differs significantly according to when computers were first used and the length of both Internet usage and computer use.
