Gaomi city Experimental Middle School, formerly known as gaomi city Adult Secondary Vocational School, was founded in 1985. 15 years later, a large number of secondary professional and technical personnel have been trained for high-density economic construction. With the development of market economy and the change of educational situation, high school education is developing vigorously. In order to meet the requirements of urban senior high school education, in July, 2000, with the approval of Gaomi Municipal Party Committee and Municipal Government, adult secondary school tried to be a comprehensive senior high school. In March 2004, it was renamed as "Experimental Middle School" and passed the acceptance of "Provincial Standardized School" in May 2005. It has been revoked and merged into gaomi city No.4 Middle School on July 20 12. The old school site is gaomi city No.5 Middle School.
