Santisimo Rosario Integrated High School (Filipino: Pinagsamang Mataas na Paaralan ng Santisimo Rosario, abbreviated as SRIHS or Stmo. Rosario IHS) is a public secondary school located at Barangay Santisimo Rosario, San Pablo City, Laguna, Philippines. It was established in 1995 and offers junior and senior secondary education. The senior high education course consists of agriculture, fisheries, and general education. It is the first public high school in San Pablo City that has produced senior high school graduates since the implementation of the K-12 curriculum by the Department of Education in 2012.

History San Pablo City National High School Santisimo Annex (1995–2004) Due to an unprecedentedly increasing number of enrollees in San Pablo City National High School, the SPCNHS could no longer accommodate all the students in the city. The City Government of San Pablo City decided to establish satellite schools across the barangays, called annexes, to solve the problem. One of the barangays chosen for establishing a satellite secondary school was Barangay Santisimo. Elias Corales†, the barangay chairman at that time, donated a hectare of land to build a barangay secondary school named Santisimo Rosario Annex, according to city ordinance number 93-3 dated July 1, 1993. On June 1, 1995, Santisimo Annex started as a single three-room building standing in an open field without fences. Four pioneer teachers were assigned to Santisimo Rosario Annex: Ronie Nacario, who was the first designated as Teacher-in-Charge, Teresa Yema, Maritess Fandiño, and Michelle D. Benedictos. In 1996, Editha L. Fule was assigned as Teacher-in-Charge of Santisimo Annex. Since 1996, additional school buildings have been constructed with the help of the local government, the parents and teachers' association (PTA), and non-government organizations (NGOs). In 1999, the first commencement exercises (four-year curriculum) of Rosarians were held in Rizal Hall, San Pablo City Central School. In 2001, the school perimeter fence was built. A major school landscape project was initiated by the freshmen in 2003, and the institution hired Jayson Bargados, the first security guard for the school's security. The first computer room was built in 2004 with the help of the Personal Computers for Public Schools (PCPS) program by the Department of Trade and Industry (DTI).

Santisimo Rosario National High School (2005–2018) In 2005, a major restructuring of faculty members occurred. Half of the original faculty members were transferred to other schools and replaced with newer set of teaching force and in the same year Santisimo Annex gained independence from San Pablo City National High School and renamed as Santisimo Rosario National High School. After gaining a new school identity, the white-green uniform was replaced by aqua green in June 2006. The use of flash drives as storage devices instead of floppy disks for saving documents was introduced and another school renovation led by school volunteer Paulton Sityar was held in the same year. Internet access was first made possible by the Gearing Up Internet Literacy & Access for Students (GILAS) project in 2007 spearheaded by Airnel Abarra. Also a treehouse was built inside the campus for the preparation of hosting the Science Camp. In 2012 Physical Education uniforms were standardized. Due to the remoteness of Barangay Atisan which was located on the foot of the Mount Malepunyo and San Isidro National High School and can no longer accommodate more students from that barangay, the SRNHS extension was established.

As the DepEd shifted to the K-12 curriculum, Santisimo Rosario NHS gathered accreditation to offer a senior high school program. Due to the proximity of the school in the rice fields and Barangay Santisimo is an agricultural area, the institution offers senior high school program specialized in agriculture, fisheries, and general education track. In 2015 the last batch of old curriculum was graduated within the same year senior high school program began. In 2016, the senior high school building was built. The first commencement exercises for senior high school graduates were held on April 6, 2017. The General Academic Studies senior high course was opened in June 2017. Also within the same year, greenhouses were donated by the Department of Agriculture. SRNHS's first and oldest school building was upgraded into a 4-story building to accommodate even more students.

Santisimo Rosario Integrated High School (since 2019) In 2019, because the senior high school and junior high school buildings were in the same area and location Santisimo Rosario National High School was renamed as Santisimo Rosario Integrated High School as declared by the Department of Education. Also the SRNHS extension in Brgy. Atisan became a fully independent institution renamed as Atisan Integrated School.

Uniforms

In earlier years as Santisimo Rosario Annex, the uniform of San Pablo City National High School was used. It was a white polo and slacks for boys and white for girls. It was a white blouse, a green checkered necktie and a skirt. The "Tuck-IN" (tucked polo clothes) Policy for boys was strictly implemented. When it became a National High School, a new uniform was introduced where the boys wear aqua-green polo and slacks while the girls wear an aqua-green blouse, navy-blue (with multiple colored grid design) skirts, belt buckles, and necktie. The new uniform was conceived by Editha L. Fule. These new uniforms removed the "Tuck-In" Policy which was implemented for boys. On its first and early deployment, it caught the attention of many private and public schools, mistakenly identified as a newly established school, and the students were always asked what school they came from. Wearing of slacks for senior high school girls and the aqua-green senior high school uniform was introduced in 2015. Physical education uniforms often changed annually until they were standardized in 2012. The standard physical education uniform is an aqua-green T-shirt and gray jogging pants with a dark green strip on the right.
