In December 2023, Université Paris Cité/Learning Planet Institute and the Marie Curie Alumni Association (MCAA) kicked off the Network of Researchers for Citizen Science (NR4CS). The network was established within the framework of a European funded project called European Citizen Science (ECS) and more particularly under one of its ‘work packages’ that seeks to establish the European Citizen Science Academy. An ambition of this network is to promote the use of citizen science as a viable research method with its considerations. It is designed for researchers interested in or experienced with citizen science to exchange ideas and knowledge, ask questions and share resources. This document regroups the resources collected from the NR4CS Training Series 2024 organised between March to October 2024 on different topics relevant to citizen science. 1. Webinars of the training sessions. 2. Summary of the training sessions. 3. Presentations from trainers and network members.
