Each contest sponsor has slightly different rules concerning which scores of individual CTDXCC club members will be eligible for inclusion in the CTDXCC club score.

	For ARRL radio contests, the CTDXCC is classified as a Medium Club, and can choose to use either any score made from a station in the South Texas (STX) section, or choose to use scores from within a 175 mile radius of a designated center, provided that all operators live within either the section or the radius (as appropriate.) For the most part, the 175 mile radius centered on 29.9° N, 97.5° W has been a better fit for the club. CTDXCC members who wish to have their score count for the club competition score must designate the club in their Cabrillo log as "Central Texas DX and Contest Club".
	For CQ magazine sponsored contests, all stations that contribute to a CTDXCC Club Competition score must lie within a circle of 275 kilometers radius, centered on 29.9° N, 97.5° W, or be operating on a DXpedition "specially organized for operation in the contest." CTDXCC members who wish to have their score count for the club competition score must designate their club in their Cabrillo log as "Central Texas DX and Contest Club".
	The National Contest Journal sponsors several contests with Team Competitions, which differ in many ways from the Club Competition offered by ARRL and CQ. For NCJ sponsored contests, all stations that contribute to a CTDXCC or "Austin Powers" team score must be pre-registered with the NCJ before the contest. Only single operator contest entries can contribute to team scores, and not every member of the team must also be a member of the CTDXCC or operate from our traditional area. Teams are usually organized on the CTDXCC club email reflector.
	The Texas QSO Party offers a Texas Club Aggregate Award to the Texas club with the highest total score from the sum of all summary sheets submitted across all categories. The club name, "Central Texas DX and Contest Club," and call sign must be identified on each of the individual Texas QSO Party Summary Sheets to be included in the count.
