As the COVID-19 pandemic evolves, IEST has been making decisions about in-person training, conferences, working group meetings, and networking based on the guidance of health authorities. During this time, IEST Working Groups have continued to host virtual meetings on web-based platforms such as WebEx, GoToMeeting, or Microsoft Teams. As meetings are scheduled virtually or in-person, they will be listed here.  Everyone is welcome to observe any scheduled WG meeting of interest. Working Group Chairs will send meeting details and instructions to request information about observing a meeting.  Please check back for an expanded list of WG meetings and dates. WebEx links are available from IEST. Please contact
