The Projects profiled must involve participants in a way that can genuinely be considered citizen science. For guidance, please refer to ECSA's Characteristics of Citizen Science. The projects can be short-term or long-term initiatives, projects without an end date, or even one-day ‘Bioblitz’ events.

Citizen science projects can involve voluntary participants (citizen scientists) in many fields of research, in many stages of the research process - from data collection and volunteer mapping, through data interpretation and analysis, to publication and dissemination of results.

Additionally, projects profiled on the platform should engage as much as possible with the ECSA 10 Principles of Citizen Science.
