The name Hadaf (English: goal) also served as an acronym in Persian for honar (art); danesh (science), and farhang (culture).
In 1974, when the government initiated national mandatory free education for all students from primary to the end of intermediary grades (8th grade), three elementary and four intermediary schools of the Hadaf Group were transferred to the public school system.
From 1951 to 1976, a total of 15,588 students had graduated from Hadaf high schools: 8,596 in mathematics branch, 6,960 in natural sciences, and only 32 in humanities.
[2] Hadaf Group was formed as a joint stock enterprise with a starting capital of 350,000 rials ($5,000.00) in 1950, of which 270,000 was provided from the revenues of evening courses offered from 1948 to 1950 and the remaining was given by the founders and other shareholders.
Although the property of the Hadaf Group belonged to the shareholders, annual revenues were often invested for the establishment of new schools, construction of new buildings, and expansion of labs and libraries.
