The purpose of this study is to develop an objective instrument to measure ICT utilization ability of day care center teachers and verify its validity and goodness of fit. With the developed scale, the survey was conducted with 297 day care center teachers. As a result, the reliability of all questions was over .6, and the construct validity of the instrument consisting of 20 questions in 4 factors was verified in exploratory factor analysis. As a result of performing confirmatory factor analysis, it was found that GFI=.949, AGFI=.898, and RMR=.029, indicating that the goodness of fit index is sufficient to be used as a measuring model. The scales of ICT utilization ability are composed of 4 factors: Factor 1 is called editing, Factor 2 is program application, Factor 3 is installation and maintenance, and Factor 4 is named communication. With these factors, the measuring device for ICT utilization ability of day care center teachers, which is composed of a total of 20 questions, is confirmed.
