Furthermore, very important for the school's spirit and an indication of its special status is its scholarship program (funded by the parents associations and the alumni club SAKA) which has given numerous students from all socioeconomic layers the opportunity to study there.

Later, Emmanuel Benakis who has been a major donator for the college, was named emeritus member and was replaced at the committee by his son Antonios.

That same year, the Benaki Hall was dedicated by Eleftherios Venizelos, then Greece's Prime Minister and an ardent supporter of the school.
