The objective of this study was to investigate the factors influencing Israeli teachers who participated in the national 'Laptop for Every Teacher' program (LET) three-year technology integration program. We assert that although there are several variables influencing the success of such an extensive ICT integration program as the LET program, school management attitude is crucial, and a key factor for the program's success. The results of the analysis indicate that the variance in attitudes toward technology use is explained by support from management, technology use before the training, and seniority in teaching. Two main conclusions are drawn: A top-down initiative forcing the school administration to participate in a long-term process aiming at changing the school's culture cannot succeed without engaging the principals into the program and advancing them to technological leaders. Additionally, without the schools' administration support, teachers are more likely to continue teaching in the method with which they are most familiar.
