Abstract-Information and communication technology (ICT)has become part of everyday life for the many people in business, entertainment, education and many other areas of human activity. Students in primary school are just beginning to learn and accept new ideas, show a maturing creativity, develop critical thinking and decision making skills. ICT enriches all these processes. In education, the successful integration of ICT into learning and teaching depends on teachers' attitudes and their ability to use communication technologies, not just competently, but with skill and imagination. Experience is required with the medium, however, but ICT use in education has been largely ignored in Saudi Arabia. The study described here investigated the factors influencing the adoption of ICT as a teaching tool by teachers at Saudi Arabian primary schools. Analysis of the data showed computer literacy and confidence with technology registered a significant positive effect on the study, participants' effort expectancy, which in turn positively influenced their behavioural intention to adopt ICT. On the other hand, Saudi culture, social conditions, system quality, and other obstacles discourage the uptake of ICT by primary school teachers. The findings of this study will assist the Saudi government to enhance the positive factors and eliminate or reduce the negative factors to ensure successful adoption of ICT in primary education by teachers.
