The school was established by Julia Paprocka in 1853. In 1924, it expanded from seven grades to eight. It had conditional, partial accreditation as a state high school. The post of the school principal was held by Helena Paprocka (1918–1919), Eugeniusz Przybyszewski (1921–1924), Mateusz Frenkiel (1925–1929), and Regina Appel (since 1931).
It was located at 27 Zielna Street. It changed its name several times – over the period of its existence, it was called the Helena and Wiktoria Paprocka Seven-Grade Girls’ High School (until 1925); the Helena Paprocka, Leon Okręt, and Antoni Paprocki Girls’ High School (1925–1926); the Wiktoria Paprocka, Leon Okręt, and Antoni Paprocki Girls’ High School (1926–1927), the Leon Okręt and Antoni Paprocki Girls’ High School Established by Helena Paprocka (1927–1934); and, eventually, the Helena Paprocka Private Senior and Junior High School (until 1939). It was officially known as the State School No.152.
The school was one of the largest facilities of its kind in Warsaw. In 1926, it had seven grades, seven “departments” (classes), and a total of 125 students.
In the academic year 1930/1931, it had a total of 130 students in five “departments.” The school had 29 students in preparatory classes, 56 in junior grades, and 178 in senior grades. The tuition fee for one student, depending on the grade, varied from PLN 960 to PLN 1,040.
