This study examined Greek kindergarten teachers’(n= 396) perceived preparedness for computer use in the preschool classes and the potential difference between computerexperienced and non-experienced group of teachers. Attention was given to the relationship between perceived preparedness and a number of other psychological constructs that the relevant research literature has revealed as significant factors, namely: internal locus of control, perceived stress, attitudes toward computers, perceived usefulness and ease of use, and computer anxiety. The data analyses confirmed the hypotheses concerning the differences between the two groups of teachers with regard to their sense of preparedness as well as among the variables intercorrelations. In addition, based on regression analyses, different patterns of predicting variables were revealed for each of the two groups.
