To be a judge, you must be able to judge the work the contributors actually did and evaluate how well the work does what it is intended to do. You are not required to be an STC member to enter the competition or to be a judge.
Though all judges should have some experience in technical communication, graphic design, or a related field, you don't need to be a 20-year veteran to be a judge. Just be willing to devote some time to give quality, constructive, and impartial feedback.
Judges will be invited to a Judges' Orientation meeting to learn about categories, forms, and guidelines for the participating in the competition! Details are coming soon!
