The authors describe the Maryland Technology Academy Leadership Program and present findings on the program’s effects from an independent evaluator. The program was launched in summer 1999 to build technology integration leaders who could promote and support the use of technology in schools throughout Maryland. For over four years of operation, the program provided an intensive professional development experience to more than 450 educators, most of whom were school-based. Components of the professional development included collaboration with colleagues, development of authentic products, systematic follow-up support, and engaging in reflection on teaching. The program was quite successful in changing participants’ attitudes and beliefs about the potential of technology and themselves as technology users, and continues to serve as a mechanism to build a network of technology leaders across the state.
