Class 3A Softball How to Qualify & League Alignment
For 3A, a minimum of 17 games must be played for postseason eligibility. 32 teams advance to the regional bracket through league play and CHSAA Selection and Seeding Index. All league champions are automatic qualifiers. In order to qualify as a league, the league must have a minimum of five teams. Schools in a multiple-class league may earn an automatic qualifier for their classification only if they win the league outright. This will mean that if a 3A or 5A school wins the multi-class league title, any 4A school in that league can only qualify for the 4A regionals through CHSAA Selection and Seeding Index. The top 32 teams in the classification based on the final CHSAA Selecton and Seeding Index will qualify for the post-season bracket. Each conference champion will automatically be placed on the playoff bracket. Conference champions are determined by the conference Bylaws or policies. If a conference champion is not ranked in the top 32 based on the final RPI/MaxPreps ranking, they will replace the lowest-ranked team that is not a conference champion in the top 32.

Seeding Criteria: Regionals will be seeded by a committee of administrators appointed by the CHSAA assistant commissioner responsible for softball and will utilize the following process: All qualifying teams will be ranked using CHSAA Seeding and Selection Index. The eight teams that rank highest by seeding criteria will host the round of 32 tournaments. The remaining teams will be placed on the bracket, using the same system as above, avoiding first round league match-up. The committee may elect to move the bottom eight teams for geographical purposes.
3A State Finals: The 16 state qualifiers will be reseeded 1-16 based on the above criteria and play a single elimination tournament. Winners of each round of 32 site will be seeded 1-8, 2nd place teams from each site will be seeded 9-16 based on the above criteria.
