Basic Education High School No. 9 Mandalay

The school was founded as St. Peter's High School by the De La Salle Brothers,[3] a Roman Catholic order on 1 May 1897.[4] It was the first La Sallian high school founded in Upper Burma, and the third in the whole Burma after St. Patrick's in Mawlamyine and St. Paul's in Rangoon.

St. Peter's High School was started teaching over 80 students. In 1924, there were 11 teachers and 350 students, including 130 resident students.

Brother Director John managed the school for 18 years until he moved to St. Paul's in 1915. The swimming pool was constructed during his administration. Brother Clementian served as Brother Director from 1933 to 1948 for the first time, and from 1950 to 1956 for the second time. In 1952, Primary School was opened at the two-storey hall (now Nyana Hall) on the left side of the east gate. In 1955, a new Chapel and Study Hall were extended at the three-storey building. In 1957, during the administration of Brother Director Peter, a single-storeyed Kindergarten Hall was built on the southern campus of the school. It was reconstructed as a two-storey building (now Thiha Hall) in 1962–1963.

Since it was opened, the school accepted boys only for some time. The all-boys school was among the few early schools that educated the children of the country's British officers, the Anglo-Burmese, the Anglo-Indians and the wealthy Burmese.[5] The language of instruction was mainly English in the early days, and bi-lingual for some classes in the later days. There were also some Hebrew classes for the Jewish.[6]

General Ne Win's military government nationalized the school in April 1965, and changed the name to State High School No. 9 Mandalay (SHS 9 Mandalay). The primary language of instruction became Burmese. The school, which used to have a "Roll of Honour" for its outstanding students, steadily lost significance, partly due to the new requirement to attend nearby schools as much as possible.

The school library is open during one-hour lunch break. Librarian and members of school library committee (teachers) manage and maintain the library systematically in line with the instructions of the principal. Member cards for students are free of charge. There are hundreds of books, inclusive of encyclopedias, written in both English and Burmese.

Both language and experimental science labs are available. Chemistry, physics and biology labs have enough teaching and learning aids for highschool students. Students have to join science labs when necessary for their studies, maybe once or twice a month.

Co-curriculum activities such as morals, life skills, arts, music and physical training are available for all levels of students.

Having sufficient facilities and good training, BEHS 9 Mandalay is well known for its students winning medals in basic education level tournaments every year.

As all public schools in Myanmar are required to form School Council, BEHS 9 Mandalay forms its one with five houses— Anawratha, Kyansittha, Bayintnaung, Alaungpaya and Bandula— every year. The school council consists of the head (principal), five leading students from the 9th Standard, five leading teachers from each team, six representatives of six standards (Grade 6 to Grade 11) and one secretary from 10th standard. Each team has to do some chores, for the cleanliness of its class and the school, in group each day before the school begins its classes. In the last period of each week on Friday, all five teams work in pairs for the maintenance of the green environment in their respective areas. All of their work mark as scores for each team. According to the sequence of the sores, in the first day of a school week, order in column of their teams are shown. The greater the higher.

The four stars in the badge of BEHS 9 Mandalay represents the houses of school council which were originally four houses.

St. Peter's boys band once was the most popular in Mandalay. Many awards were achieved. However the band was dissolved for some reasons.

In July 2019, school alumni co-ordinated with the principal, and formed new fife and drum corps with the current students. From August 2019 onwards, music lessons were started for BEHS 9 Mandalay's band.

On the full moon day of Waso each year, BEHS 9 Mandalay offers Waso flowers at nearby Shwe Kyee Myin pagoda, and Waso robes are offered.
