HEADS-UP is an EU-funded program that will develop various educational tools and resources to inform and enlighten teachers and front line workers dealing with young adults in all educational settings and adults at risk of online threats and radicalisation. HEADS-UP wants to build the skills of front liners through in-service training and a series of simulated videos that explicitly demonstrate the online threats people in vulnerable positions face. This practical, user-friendly set of resources will enable educators to support their target groups more effectively by teaching them how to identify and deal with potential radicalization and grooming threats.
