Teams that play at the state level must place their highest-rated player on Board 1, their second-best on Board 2, etc., through Board 4. If there are >4 players, then the team must have at least 1 player on each board, but can stack players on boards as they wish. If you do not have a full team, you must play Board 1. This means that Asha played only the best players from around the state. This win qualifies her to compete for the Missouri High School Tournament of Champions on April 18. She also qualifies for the Missouri All-Girls Chess Tournament on the same date.
As an additional note, her brother. Marcus Sliva (TJ Class of 2032) is the MO State K-6 Co-Champion alongside his two teammates from Forsyth School, Niels and Teddy.
