This girls’ high school was established by the “Chavatseles” Orthodox Society during the period of German occupation of Warsaw during World War I (1915–1918) and received its licence on 15 June 1920. However, in 1921, it lost its accreditation as state high school, partially recovering it in 1931. In 1937, it changed its name to the “Chavatseles” Private Junior and Senior High Schools. School principals were Salomea Tenenwurcel (1918–1919), Leon Niemcewicz (1921–1924), Alicja Hollender (1925-1926), and Idessa Goldwasser, later using the surname Goldwasser-Funt (from 1929).
In 1921, it was located at 18 Wielka Street. The school had seven grades and was humanities-oriented, with Polish nominally serving as the language of instruction. It was not accredited as a state high school, but was organised into eight “departments” (classes) with 135 pupils. The school principal was Alicja Hollender, who, according to historical sources, held two PhD titles – one in philosophy and another in medicine.
In the 1930/1931 academic year, the school had 126 pupils, 21 of whom attended preparatory classes, 32 attended junior grades, and 73 attended senior grades.
In 1931, the school was moved to 22 Świętojerska Street. In 1937, it had six grades.
It continued to operate secretly inside the Warsaw Ghetto.
