In 1882, some of the first high school classes offered at Parsons were held at McKinley School. The first Parsons High School building was built in 1893 and cost $30,000. It was on southwest corner of Twenty-sixth and Main Streets. The building served the city in its original capacity for just over 30 years. When the new high school / junior college was built on Main Street in the late 1920s, the old high school become West Junior High School. By the 1950s, voters agreed that a new secondary school should begin construction. In the late 50s, the current Parsons High School building was completed. In 2009, a major renovation project was undertaken for Parsons High School and was completely finished before the start of the fall semester. It gave Parsons High School the modern look that can be observed today.
