Citizen science is the involvement of the public in scientific research – whether community-driven research or global investigations

Citizen science is the involvement of the public in scientific research – whether community-driven research or global investigations. The Citizen Science Association unites expertise from educators, scientists, data managers, and others to power citizen science. Join us, and help speed innovation by sharing insights across disciplines.


Whether through grassroots action or technology-mediated crowdsourcing, there has been a rapid increase in public participation in scientific research (citizen science, volunteer monitoring, Pro-Am partnerships, community-based participatory research and more).

The success of these initiatives takes dedication not just from volunteers, but from organizers, educators, scientists, data managers, technology specialists, evaluators, and others. Practitioners (paid or unpaid) work to design, support, and implement projects, manage and use data, and evaluate and research individual initiatives or the practice itself.

An emerging branch of Citizen Science are Community Mapping projects that utilize smartphone and tablet technology. For example, TurtleSAT is a community mapping project that is mapping freshwater turtle deaths throughout Australia.

We can speed innovation by sharing insights, across all fields of study, among peers who support these initiatives – our membership already exceeds 4,000 individuals from over 80 countries. Our early services to support idea-sharing include a conference and a journal.

The Association has been years in the works. Momentum to solidify into a more formal organization came about as a result of the Public Participation in Scientific Research Conference, held in Portland, Oregon in 2012.

Members have the opportunity to shape the development of the Association by voting on key decisions about direction, priorities, and leadership. Members and non-members alike can sign up to receive updates through a monthly newsletter, and are welcome to join a discussion listserv for sharing questions, ideas, innovations, and announcements among peers in this field.
