The Professional activities section is for information about your membership affiliation with an organization, your activities in service of an organization, invited positions, and distinctions.
- Choose Membership when you are a member of a society / association trade or industry body. This does not include honorary memberships and fellowships which should be listed under Invited positions and Distinctions.
- Choose Service for significant donations of time, money, or other resources to an organization or community. This includes voluntary work: (e.g., society officer positions, elected board position, standards board member, editorial board member, review editor, conference organizer, conference panel chair, committee work, project work, extension work).
- Choose Invited positions for an invited non-employment affiliation. This includes formal acknowledgement of your academic effort through honorary titles and/or positions (e.g., honorary fellow, fellow member, guest researcher, Emeritus professor, visiting lecturer) which require no specific service. May be paid or unpaid.
- Choose Distinction when you have received honorary and other awards, distinctions, and prizes from an organization in recognition of your academic or other achievements (e.g., trophies, cash prizes, non-cash prizes, medal, honorary degrees, honorary member).
An organization may ask your permission to add information about your affiliation with them, but you can also add these activities manually.
- Scroll to the Professional activities section and click +Add.
- Select the desired option from the drop down menu.

The fields in each area are divided into three sections: organization, the selected professional activity, and visibility.
