Contemporary educational systems in Western societies are being redefined within the context of technological and scientific evolution in relation to socio-economic globalisation. Therefore , it is important for educational authorities to design staff development programmes with a view to helping professionals adjust their ideology and practice effectively in order to contribute to the implementation of a learning culture and the formation of the “knowledge-based society”. The aim of the present paper is to review the field of teaching professionals’ professional growth, identifying weaknesses, highlighting trends and practices, and providing suggestions, most important for professionals and educational authorities in Greece where staff development programmes fail to reach standards met by other European countries. It focuses on staff development models that enable facilitation of teachers' efficacy, cognitive development, and career development, as well as teacher collegiality and the improvement of school culture, r econceptualising schools as “learning organisations”.
