Glendale High School opened its doors in 1963 on 40 acres in southeast Springfield, Missouri. It is a four-year comprehensive high school with an enrollment of approximately 1,400 students and has been accredited by the North Central Association of Secondary Schools (AdvancED) in 1964. AdvancED is the unified organization of the North Central Association Commission on Accreditation and School Improvement. Glendale enjoys a comprehensive and diverse academic program, which meets the needs of the entire student population, including gifted and special education students. The majority of the teachers on staff hold a master’s or higher degree. The school restructured from a six-period day to a four-block delivery system in 1995-96.

The physical plant has changed a great deal since the school opened, with a 17 classroom addition in 1964, an auditorium and practice gym in 1991, an elevator in 1994, and band room in 2001. Community patrons successfully passed a bond levy, and Glendale benefited by having air conditioning, new thermal double pane windows, and entry doors installed during the 2005-2006 school year. During the spring of 2009, Glendale opened eight new science/technology classrooms, journalism lab/studio, professional learning classroom, health services suite, guidance and counseling center, and a new main office complex. Phase I of the Falcon HPER (Health, Physical Education, and Recreation) Facility also opened in the spring of 2009. This project was funded by private individuals and businesses.

Glendale students consistently demonstrate high district/state averages and scores in attendance, graduation, post-secondary education enrollment, End of Course exams and ACT scores.

Glendale students and staff are leaders in Peer Mediation and Character Education. GHS Peer Mediators are role models and provide training for student leaders from other Missouri schools. Character Education activities have included the formation of a site-based Character Council, specialized character training, and character essay contests. 

Glendale was designated an A+ School in the year 2000 by the State Board of Education. More than 600 Glendale graduates have qualified for A+ certification since designation. The primary goal of an A+ School is to assure that programs, interventions, and incentives are in place to encourage all students to stay in school, make career plans, tutor younger students, and graduate with the skills and knowledge required for career success or post-secondary education. As an A+ School, Glendale works closely with business and higher-education leaders to provide community-based activities and opportunities for its students. Glendale has two enhanced business partnerships that include Bass Pro, Springfield and Chase Bank. McDonald's and American National Property and Casualty Company provide various instructional materials and supplies for students and staff. Members of the A+ Advisory Board include college, business, information technology, community, staff, parent, and student representatives.

Glendale High School was recognized as a Missouri State High School Activities Association Leadership School in 2007-2008 and 2008-2009.
