Your chapter must be AFFILIATED (meaning payment received) by November 15th in order to be eligible for competitive events. Please note, this is not a postmark deadline, and the checks must be received to National Headquarters by the November 15th date.
Students can still be added after the deadline, and still be eligible for competition, as long as your chapter was submitted by November 1st and affiliated by November 15th. Subsequent affiliations are welcomed to affiliate new members that may have not met the initial deadline.
IF you need to change a students affiliation type or name, you can go under the member list on the portal, and click the person icon under "request change" to make the needed changes.
