Researchers and practitioners recognise the crucial links between ICT Access and ICT Ability in promoting ICT Use. This paper is the third in a series exploring this link, and concentrates specifically on approaches to ICT Ability. This paper considers literature and research relating to ICT PD from a variety of sources and countries. Building on a model proposed at the ITEM2002 conference, the paper explores research conducted in a selection of schools in England, and then discusses one implementation of ICT PD programmes in Australia. Results of this implementation are discussed, concluding that it may be a valuable model for other schools seeking to leverage ICT use for educational innovation.
