The Senior Class promotes school spirit and activities for the McKeesport Senior Class each year. Activities include a yearly fashion show and the senior prom along with numerous fundraising opportunities. The Senior Class consists of five elected positions: President, Vice President, Secretary, Treasurer, and Public Relations, along with an Executive Board.

The members of the Executive Board are in charge of selecting graduation announcements, making selections for the class song, class flower, class motto, class colors, and creating the categories for the Senior Class superlatives.

Recently, the Senior Class has stemmed off into a junior branch in which the seniors and juniors created class t-shirts. The Senior Class works closely with the Student Council to promote a positive school atmosphere.
