The Commonwealth of Learning (COL) and the Asian Development Bank (ADB) are pleased to provide this toolkit for your use and we sincerely hope that it will be a valuable resource for anyone planning and conducting training in the practice of open and distance learning. The development of this toolkit and others, in various topics related to open and distance learning, has involved the time and dedication of a number of organisations and individuals.
