Koler decided to build the gymnasium similar in spirit to those in Europe which would provide its students education in Hebrew that would allow them to enter a university.
Koler carefully chose the teachers for the school – most of whom were immigrants from Eastern Europe whom he knew personally from his days in Poland.
The school quickly developed into a very prestigious and selective institution, providing the highest levels of education in the country.
After its sale to the Tel Aviv municipality and during the first few years after the creation of Israel the school continued to be directed by David Rachavi at its previous address.
The move proved to be successful, increasing the number of students and producing many notable artists such as Maor Cohen, Rami Heuberger, Erez Tal, and Danielle Wircer.
