Kearney High School was built in 1997 and has a population of around 900 students. A renovation in 2019 included the installation of over 2,000 Infinity Seat Modules in the gym. The bleachers on the main floor are wall-attached VersaTract telescopic bleachers with Smart Rails and panelam decking. The bleachers in the upper deck areas are permanent and include ADA modular decks for cameras and wheelchair access.

In 2023, Irwin returned to the school to replace the 504 chairs in the auditorium. The Marquee model 51.12.10.4 chairs were supplied with plastic and powder coating in charcoal grey. The laminate insert aisle panels are surfaced with Nevamar Wrought Iron. The backs and seats were upholstered with Designtex Ulster Steel fabric.
