Many educational institutions have been using lots of technologies in classrooms to increase the effectiveness of learning activities. In recent years, tablet PC (TPC)'s have been the primary of these technologies. Technology especially comes to exist in busy environments and gets even more important in the environments where students defined as "digital native" can use technology effectively. However, there have been no sufficient studies about the acceptance, readiness and use of tablet PC's in secondary schools. In this research, secondary school students' acceptance of tablet PC was examined with technology acceptance model, and readiness variable was also added. As a result of the research, it was found that secondary school students' acceptance level of tablet PC is explained at a good level. It was also found that readiness is an important variable for intention to use tablet PC. Also it was found that self-efficacy and anxiety in acceptance of tablet PC are important external variables.
