Thursday, June 25th the Iowa State Athletic Association released the 4A Substate Groups for playoffs. 6 teams are placed in each substate, with seeding to be determined up to July 4th or each teams first 30 games. Seeding is based upon points earned for each win, with a win over 4A schools worth 4 points, 3A worth 3, and so on. The total points are then divided by total number of games played.
The number 1 seed will retain home field advantage throughout the playoffs. Once seedings are set, all 6 teams will play each other with the #1 vs #6, #2 vs #5, and #3 vs #4 playing at the higher seeded team's field. The highest seeded winner will receive a bye for the second round with the other two teams playing each other, once again with the higher seeded team in the matchup gaining home field. The winner of the second round game will play the remaining team at the highest seeded team's field in the substate final, with the winner going to the state tournament.
