Performance and technical events are two of the largest categories of events that members can participate in. To find a full list of these events, look in your Chapter Planning Guide. Although these two types of events look similar, the thing that sets these two apart is the presubmission component.
Performance events do not have a presubmission component, meaning that your entire score on your rubric is comprised of your performance at the conference. Performance events include business ethics, emerging business issues, etc. These events are usually a presentation given to judges without any sort of content turned in beforehand.
Technical events comprise of a presubmission, meaning that you have to turn in a product by a certain date before the conference. For example, if I were competing in Mobile Application Development, my presubmission component ( an app ) for SLC would have to be turned in before SLC by the date that is designated in the Chapter Planning Guide. Alongside this presubmission, technical events have a performance component as well on certain levels of the competition.
