The problem addressed by this study was technology was not consistently utilized in private high school teachers' instructional practices. Without technology-infused instruction, students are not prepared to participate in our global community. The purpose of this descriptive qualitative study was to investigate private high school teachers' perceptions of factors that contributed or presented barriers to incorporating technology in their instruction. The framework of this study was Rogers' theory of innovation diffusion. Twenty-five teachers responded to the questionnaire and of those, 10 participated in semi-structured interviews. The first research question was, what are teachers' perceptions of the factors that contribute to their implementation of technology-infused instruction? Themes emerged regarding time, students' benefit, and professional development. Research question two was, what are teachers' perceptions of the barriers that hinder teachers' implementation of technology-infused instruction? Themes developed about technology failure, students don't benefit, and traditional teachers don't benefit from technology. Findings for the study were that private school teachers do not perceive extra time to learn and practice technology or technology failures as barriers to utilizing technology. However, teachers would benefit from professional development that is supported on campus and that incorporates technological apps in their content area. Teachers who were deploying technology-infused instruction prior to the pandemic experienced less problems adapting to virtual instruction than those who utilized traditional teaching methods. Recommendations for practice included streamlining duties to generate more time in the school day for learning technology, providing adequate support to learn technology, and utilizing peers to help traditional teachers embrace technology and develop a constructivist practice. Recommendations for research included elucidating the relationship between investing time and a growth mindset.
