The motive of this research paper is to investigate the teachers' adoption of information and communication technology (ICT) in Pakistan and the application of extended UTAUT model in a new context. A number of factors can cause changes in intention towards the usage of ICT including social, behavioral, and psychological factors, but this study, using the UTAUT model, is limited to examining the behavioral determinants of teachers' acceptance of ICT. To achieve the objective, a quantitative approach was adopted where questionnaire‐based data were obtained for analysis. The analyses were conducted on 341 valid responses that were collected from the teachers of high secondary schools in Khyber Pakhtunkhwa province, Pakistan. Getting the data analyzed through SPSS and AMOS, our results show that performance expectancy, efforts expectancy, social influence, facilitating conditions, and information technology capabilities play a significant role in shaping teachers' adoption of ICT. Moreover, behavioral intentions mediate the relationship between the predictors and ICT usage. Based on the findings of this paper, administrators and government are recommended to spend additional efforts and money by launching programs for their teachers to increase the usage of ICT in their teaching and schools. The study provides numerous insights for teachers, school administrators, and government ICT‐based smart teaching and learning institutions.
