The last graduating class from this facility occurred in 1929, after which the building was repurposed for various educational levels, eventually serving as a sixth-grade school until the late 20th century.

The next major transition occurred in the fall of 1958, when a new Junction City Senior High School was opened on Eisenhower Drive, serving students in grades ten through twelve.

[4] As the need for modern educational facilities grew, the district placed a bond initiative for a new high school before voters, who approved the measure in November 2017.

The new Junction City High School spans approximately 437,000 square feet and opened its doors on August 25, 2021, amid ongoing construction.

The school also offers career-based certifications in various programs, including automotive, welding, ServSafe, emergency medical technician (EMT), certified nursing aide (CNA), and others.

Students must complete four credits in English/language arts, including courses such as English I, II, III, and IV or their AP equivalents.

[9] For the class of 2028 and beyond, the requirements remain similar, with the addition of a 1-credit STEM or CTE (career and technical education) course and 0.5 credits in financial literacy, to be taken in the junior or senior year.

Career and real-world examples include community service, workplace learning experiences, and industry-recognized certifications.

These include academic organizations, arts programs, and community service groups, along with special interest and technology-focused clubs.

[8] Junction City High School also offers an Army Junior Reserve Officers' Training Corps (JROTC) program as a voluntary elective.
