Members for country teams are chosen based upon the need to the particular country in the data, expertise and interest in careers and related scholarship, and professional values that include collegiality and a service orientation to stakeholders who benefit from our research. Membership decisions are made by the steering committee (under organization link).In general, it is not possible to join an existing country team. Those wishing to have membership considered should write to Jon Briscoe at email@example.com. Regions in particular need of representation are Southeast Asia, Subsaharan Africa, and the Middle East. That said, potential colleagues from any country are welcome to inquire. Considerations about optimal group size will be made with all new applications.
