We've made some changes in the eligibility rules for ACF, one of which will pertains to high schoolers in dual-enrollment programs. Here is the new rule, with the changed sections emboldened.
For high school tournaments, players must be enrolled at the school for which they are playing, or have graduated in the same academic year that the tournament is being held. For collegiate tournaments, players must be taking classes for credit (or doing equivalent undergraduate or graduate work) in a degree program, during the academic year in which the tournament takes place, under the aegis of the school for which they are playing. Summer sessions are considered part of the preceding academic year for the purpose of this rule only, but not for any other rules. All graduate students who are doing work towards a degree are eligible, as are all high school students dual-enrolled in college programs. Holding any prior degree from any institution will not render an otherwise eligible player ineligible. The taking of minimal course loads for the sole purpose of retaining eligibility at an institution that the player would not otherwise be attending is prohibited. Determining whether this is taking place is at the sole discretion of the eligibility committee; players who do not meet the letter of the eligibility rules laid out here but who believe that their circumstances merit consideration should apply to this committee before attempting to register for any ACF tournaments. Sanctions for players discovered to be ineligible are discussed in rule C.8.
The ACF eligibility committee consists of the head editors of ACF Fall, Regionals, and Nationals, or their designated proxies, who must be Full ACF members. This committee is the final authority on any question of eligibility. The following parties may petition the committee: any player regarding their own eligibility or the eligibility of any other player, any coach or other team adviser, or any director of an ACF tournament. The committee may be petitioned both before an ACF tournament and up to three weeks after the conclusion of the event. Players who question their own eligibility must petition the committee a reasonable amount of time before the tournament that they wish to play. If the committee retroactively declares a player ineligible, sanctions are available under Rule C.8. Once the committee rules a player eligible or ineligible, that decision will stand for the entire competition year unless the educational circumstances of the player in question change, in which case the committee may be asked to re-rule. Decisions of the committee require at least two of the three votes.
