This research presents the results of a feasibility assessment on implementing ICT in Tehran high schools. Mixed method research (both qualitative and quantitative) was employed and due to the nature of research, data collection included two stages: library and field study. Using the cluster method with 362 subjects, data was collected using a researcher-made questionnaire with 0.86 Alpha reliability coefficients, and then analysis was performed at two levels, using descriptive and inferential statistical approaches (frequencies, T-test and priority setting by Li-Hi test). The results demonstrate that teachers agree on the types and features of ICT. In addition, they believe that the current status of resources, facilities and conditions for implementing ICT in schools is insufficient. The teachers confirmed the facilitating factors of ICT applications in secondary schools, which are also discussed in this paper.
