Sexual abuse allegations
In 2023, Sumner High School and its school district faced a lawsuit from a group of six students who had claimed they had been sexually abused by a teacher at the school. The lawsuit claims that the school district was aware of the sexual abuse, but did not take action until it was reported by news outlets. In April 2023, Sumner High School basketball coach Jacob Jackson was charged with child rape and molestation, and subsequently fired from his position; two lawsuits were filed against him prior to the firing. Allegations of abuse were made against Jackson as early as 2018. In April 2025, Jackson was sentenced to 40 years and three months in prison after he was convicted of 19 counts of various sex crimes against eight teenage boys.

Following Phase 2, a future Phase 3 build-out funded by the same 2024 voter-approved measure will complete the campus expansion by Fall 2032. This final phase will introduce a new Performing Arts Center, a gymnasium, an aquatic facility, athletic courts, and multi-use turf fields.
