Established in 1917, it was a rare example of a co-educational secondary school. It first focused on individual approach to students but later developed a more specific profile, providing education in mathematics and natural sciences. The school’s name changes resulted both from the transformations in the character of the institution and the status of its owners-principals: the Felicja Buki Coeducational High School (1926); the Felicja Buki-Cygielsztrajch Coeducational High School (until 1930); the Felicja Cygielsztrajch Coeducatiuonal High School (final period of its existence). The wages of the staff were set in accordance with an agreement with the Jewish School Teachers’ Union. The school was closed down in 1933.
It was located at 11 Orla Street. It had partial accreditation as a state high school, which it lost in 1928. The language of instruction was Polish.
In 1926, it had eight grades, nine “departments” (classes), and a total of 87 male and 176 female students.
In the academic year 1930/1931, it had a total of 114 students in eight “departments.” The school had 28 students in preparatory classes, 50 in junior grades, and 36 in senior grades. The tuition fee for one student in a preparatory class (Grade 0) was PLN 400–600. In junior grades (Grades 1–3), it amounted to PLN 800, while in senior grades (Grades 4–8) – to PLN 1,000.
The school had a surprisingly extensive staff compared to its relatively small number of students.
