Technology integration, the incorporation of technology resources and technology-related practices into the daily routines, work, and management of schools, is an essential component of 21st century schools. One of the most important aspects of technology integration is the role that principals play. Despite the importance of this role, many principals report that their preparation programs did not fully prepare them to lead a technology integration effort. One program designed to assist principals is the Alabama Math, Science, and Technology Initiative (AMSTI). Using International Society for Technology in Education's National Educational Technology Standards for Administrators (NETS-A) as a guide, AMSTI provides training to principals in technology integration. In an effort to describe the role of the principal in leading a technology integration initiative in 21st century schools, five AMSTI principals who exhibited excellence in technology integration were selected. Data were collected through interviews and observations and then transcribed, coded, and analyzed. From the analysis four themes emerged: lead by example, provide technology opportunities, minimize hindrances, and train regularly. Research questions were answered based on analysis of data. Several conclusions were formed by answering the research questions. Principals who were successful in leading a technology integration initiative had a shared vision that included a plan and goals for an initiative. They led by example and got faculty to believe in the merits of the initiative. Principals also showed a willingness to learn and provided resources such as training and technology for students and faculty. The final report serves as a resource for those charged with leading a technology integration initiative in 21st century schools.
