All ESTECH attendees are invited to observe Working Group meetings as they are an incredible learning experience. You may attend as many working group meetings as you wish as an observer. Once you attend 2 consecutive meetings of the same working group, you are eligible to become a voting member and help update or develop technical guidelines.

Why join an IEST Working Group?

  • Establish industry guidelines
  • Network with peers
  • Build your résumé
  • Contribute your expertise
  • Learn about topics and technology of interest

All Working Group meetings will occur virtually the week prior to or after ESTECH so attendees may fully participate in the conference. Once Working Groups have been scheduled, their date and time will be listed below. Question or need more information? Please contact Jenn Sklena at
