Produced as part of a series of three Inspiration Books, this publication centres on the topic of In-company Classes. As a guide for teachers, trainers and other educators (for example, company coaches), the book initially presents the concept of In-company Classes, confirming this as a means via which theory and practice can be brought together in a workplace setting yet distinguishing this from other forms of work experience in which teachers often play a lesser role. The publication centres on initial planning, preparation and delivery of in-company classes, adopting a “before, during and after” stance and providing an insight into the key actors and core considerations that each of these steps involves. In the penultimate chapter, a series of practical checklists and tables are also provided. Notably, the Inspiration Book on In-company Classes is available for download in English and four additional partner languages (ES, FI, NL and PT).
