As part of the 1997-1999 Teaching and Learning Enhancement Plan, the University of Queensland mandated that all its academic departments should conduct tutor training. The University's academic development unit, TEDI (the Teaching and Educational Development Institute) designed a network-based staff development strategy for the development of departmental staff designated as tutor trainers. The strategy was known as the Tutor Training Network (TTN). This paper describes the strategy and reports on an evaluation of the Network programme. The data show that although it was very successful, the network-based strategy has a limited lifespan. Nonetheless it is an effective strategy for wholesale staff development to support institution- wide implementations of policy or changes in practice.
