St. Xavier has also renovated the school grounds with Project X, an initiative to raise $28 million for new academic and athletic facilities.

[4] St. Xavier has the largest enrollment of boys among Kentucky high schools,[5][a] and had been the only school in Kentucky to have won a state championship in every Kentucky High School Athletic Association (KHSAA)-sanctioned sport open to boys before the KHSAA began sponsoring coeducational championships in bass fishing and archery in the early 21st century.

St. Xavier is one of the most successful athletic programs in Kentucky, having won 172 boys' state championships across 13 different KHSAA sports.

[8][9] This is an unprecedented feat, taking home championships in soccer, football, cross country and golf.

[20] As of 2018, the cross country team has won 6 of the last 7 State Championships,[21] and was nationally ranked in the top 15 in 2012–13.

[23] The soccer team has won eight state championships since 2000,[24] earning top 10 rankings in national polls while doing so.

[27] Project X also resulted in a new tennis facility, complete with concessions and seating for 300 spectators, a new baseball stadium and a new 6,100 seat football stadium, complete with two private suites, an 8-lane rubberized track, and new spaces for offices and locker rooms.
