CSA connects people who design, lead, manage, and study citizen science to exchange knowledge, identify shared concerns, and advance innovative work. We partner with sister organizations on other continents to engage a global conversation about public participation in scientific research. CSA brings depth to how citizen science is understood both as public engagement and as research, and shines a light on the integrity and complexity of the practice

Many people join CSA to become part of the movement to advance this field. Others join to meet and learn from new colleagues or collaborators. Still others are interested in events and activities offered uniquely for members. 

From all members, we hear that CSA is a community to call home – a place where you will be welcomed and encouraged to engage in cross-cutting conversations that you won’t find in any other organization. We hope you share your expertise with us and will join us in elevating the field of citizen science. 

What CSA offers you as a member:

As a member of CSA, you will have unique access to a broad network of citizen science practitioners from around the globe, sharing insights from the many  perspectives that are necessary for these projects to thrive. You can build your professional network and shape the future of the field by joining working groups that advance cross-cutting issues. Members drive the direction and priorities of CSA through input into key decisions. As a member, you will also receive discounts and special access to online and in person events such as our biennial conference, webinars, workshops, and online courses, as well as reduced fees to publish in CSA’s journal, Citizen Science : Theory and Practice.
