"This guide is designed to document the process and good practice in developing training material, piloting and testing it. The guide is aimed to help you (the course organiser) to plan and conduct the course. The guide includes information on the main steps and stages in sequence of designing a training course all the way to evaluation for feedback into further development. It is worth mentioning here that the design and development process of training material is anything but linear. It’s very iterative but it’s a challenge and a difficulty to capture this in a document such as this guide. Throughout the process it’s important to remember that stage evaluation is paramount and going back for modification maintains the integrity and relevance of the material. Design processes are always divided into steps and phases in order to make sure that checks and tests are carried out at the appropriate time to avoid any lengthy and costly time consuming modifications at the end."
