The Non-Formal Learning Handbook was produced within the framework of the project “Volunteers at the Interface between Formal and Non- Formal Education”, co-funded by the Erasmus+ Programme of the European Union . It aims to prepare, train and support volunteers for their voluntary service in formal and non-formal educational host organisations, offering a wide selection non-formal methods and activities that can be implemented with children, youth, differently abled young people and those at risk.
