The school opened the Walter Dlubak Athletic Center in 2009, home to the SJHS Spartans; math and science classes are also held in the building.

This picnic formerly contained a freshman vs. senior football game until it was cancelled in 2015 and replaced that same year with a class-against-class whiffle ball tournament.

On the Wednesday before Thanksgiving, the students enjoy an 11:30 dismissal as the previous year's senior class returns to the school to collect with yearbooks and reconnect with underclassman friends still at St. Joe's.

Following the shortened school day, the underclassman face off against the seniors in the annual Turkey Bowl football game, a tradition that has lasted over 30 years.

The SJHS Spartans field men's and women's teams in the WPIAL in: baseball/softball, basketball, bowling, volleyball, golf, tennis, swimming, and soccer.
